Chapter Text

“I’m so tired. I was so nervous I didn’t sleep at all last night.” Yuzuriha sighed, looking out the window.

The Hogwarts Express travelled incredibly fast, but the beautiful landscape could still be appreciated. The sun shone brightly up in the sky, and there wasn’t even a single cloud on sight.

“Yeah, I didn’t sleep either.” Taiju mumbled, his gaze also lost in the landscape.

“It’s so weird,” Yuzuriha started, her voice rising with excitement. “Even after living in Hogwarts for four years I still feel nervous on the first day.” She sat upright and turned to look at Senku, who was distracted reading the ingredients of the chocolate frog’s box. “Who did you get?”

The blond looked up at her, shrugging. “Rowena Ravenclaw, as always. I swear she follows me everywhere.”

“Maybe she knows you’re the most intelligent person to ever belong in Ravenclaw.” Yuzuriha comforted him with a smile, but Senku just snorted, ignoring her words.

“Are you also nervous today, Senku?” Taiju asked with a smile, softly kicking his friend’s ankle.

Before the blond could answer, the compartment door opened with a bang, and Chrome rushed inside.

“It took me so long to find you! How was your summer?” The brunet sat down in front of Senku with a smile, and he smiled back.

“You didn’t answer any of my calls, idiot.” Senku reprimanded.

“Wait,” Chrome shook his head, ignoring his words. “Before you scold me because I haven’t talked to you this summer, let me tell you what I’ve just found out.”

“What?” Taiju asked, leaning forward, as if Chrome was going to tell them all an important secret.

“I already know who are going to be our new classmates.” He said with a triumphant smile.

“How did you even discover that?” Yuzuriha leaned back, folding her arms sceptical.

“I have my contacts,” The brunet waved a hand around. “Anyways, we’re all going to be in class together.” He exclaimed excited.

Senku leaned back on his seat, sighing. “Finally. I was so tired of not having you in class.” The blond glanced to Taiju and Yuzuriha, who high-fived excited.

He had felt like an idiot when Yuzuriha was sorted into Hufflepuff, along with Taiju, on the Sorting Hat Ceremony. He had hated the idea of going to Hogwarts way before that, but facing everyday life with his friends in another house and on different classes made him even more resentful.

Although he had found a friend like Chrome in Ravenclaw, being away from his childhood friends still hurt him, but he’d die before admitting that.

“Who else is going to be with us?”

Chrome beamed, his eyes shining with excitement.

“I think we’re in the best class Hogwarts has ever put together.”

Senku groaned. “Come on, stop with the hype. Who are our classmates?” He tried his best to sound uninterested, but also leaned forward.

“Kohaku Tobe.” Everyone nodded in recognition, and Chrome leaned back, feigning coolness. “I kinda expected that. They know we are childhood friends, so it was about time we went to class together.”

“Kohaku, the Gryffindor quidditch girl?” Taiju asked, now confused. “Since when are you friends with her?”

“Well, she doesn’t speak much to me when we’re at Hogwarts,” Chrome responded sheepishly. “But this summer she invited me to her mansion.” He raised his eyebrows, smug.

“Do you think she still remembers that one time you entered the quidditch pitch in the middle of a game just because you thought you had seen a gem on the grass and it turned out to be the golden snitch?” Yuzuriha teased him with a smile, and Chrome glanced away, blushing.

“It really looked like a gem.” He mumbled, shaking his head, and changing topics. “Anyways, her friend Ryusui Nanami is also coming to class with us. Something about not wanting to break the sports couples because being together strengthens their bond.”

“Isn’t he her boyfriend?” Yuzuriha asked, confused.

“No. He’s her friend.”

“How do you know that? Everyone says they’re a couple.” Taiju insisted, and the brunet shook his head again.

“They’re friends, period. I just know it.” Chrome sounded extremely uncomfortable talking about it, so Senku decided to change the topic and ask something else.

“And who else is in our class?”

Chrome looked back at him, a grateful smile on his face. He was slightly blushing from embarrassment or uncomfortableness, Senku didn’t know.

“Ukyo Saionji, the archer boy.”

“Oh, I’ve seen him at the Hufflepuff common room a few times, bit I’ve never talked to him.” Taiju mused, leaning back on his seat. “Is he good? I’m afraid I’m going to be the one at the bottom of the grades list this year.”

“Yeah, I’ve heard he’s quite good. Specially at History of Magic.” Yuzuriha mumbled, but before Taiju could whine about how much he’d have to study this year, Chrome spoke.

“And the best one for last.” Everyone looked back at him instantly, and he smiled. “Gen Asagiri.”

Taiju and Yuzuriha gasped dramatically. Senku raised his eyebrows, confused by their reaction.

“We’re doomed,” Taiju whined, covering his face with his hands. “He’s the best student at Hogwarts right now. He’s going to crush all of us.”

“I’ve heard that sometimes girls and boys gather outside his classes just so they can talk to him.” Yuzuriha sighed. The blond decided to ignore all the comments and turned his attention back to the chocolate frog box.

It was impossible not to know who Gen Asagiri was. Everyone talked about him, everyone wanted to be his friend, and everyone gushed all the time about how pretty and intelligent he was, and asked whether he really was “the chosen one” —which the blond couldn’t help but think it was terribly stupid. There was no such thing as “a chosen one”.

But worst of all, he really was the best at everything. He aced all the exams and every professor and student adored him.

Being with him in class on his fifth year, with the O.W.Ls coming up, wasn’t the best news for Senku.

He had been pretty relaxed the past years, managing to get first position at class and exceeding the N.E.W.Ts exam without much effort. If he wanted to keep it like that, he’d had to start actually working hard for once.

 “Senku? Did you hear me?” Chrome’s voice brought him back to reality. He looked up at his friend. “I asked you something.”

“Sorry, I was distracted.”

The brunet sighed but asked the same question again. “How’s your dad?”

“Oh, he’s fine. He’s starting the astronaut training again next week.”

Before Chrome could speak again the train came to a halt, making all of them hold their breath for just a second.

Then, Taiju stood up excited, almost knocking his trunk from the compartment they had overhead. “Let’s go!”

Chapter Text

The Hogwarts Great Hall was packed with students. The freshmen stood awkwardly at the entrance, waiting for the Sorting Hat ceremony to start.

“There’s Kohaku.” Chrome said, turning around and glancing over at the Gryffindor table. “And there’s Ryusui. I swear, you’ll never see one without the other.”

“Was Ryusui at Kohaku’s mansion this summer too?” Senku asked, making the brunet look back at him.

“Yes, and two other Gryffindor guys… What were their names…? Kinro and… Ginro? Yeah, the brothers.” Chrome turned again and pointed with his chin at two boys who sat silently on the Gryffindor table, one of them dark-haired and the other blond. “They’re the beaters of the quidditch team. I swear those things are like cults.” Senku chuckled, softly shaking his head, and looked over at the headmaster, Kaseki, who had just stood up, ready to five his yearly welcoming speech.

“Hello, hello everybody.” He pressed the tip of his wand against his own throat, making his voice louder. “I suppose you’re all really excited to start this year at Hogwarts School of Witchcraft and Wizardry.”

Senku chuckled when he heard that, looking back at Chrome in hopes of finding someone feeling as skeptical as him about that. He didn’t, though, for Chrome was looking at Kaseki with a wide smile.

Maybe the blond really was the only one who didn’t want to be there.

“This year is going to be really exciting because…” Kaseki looked down at the paper he had in his hands, squinting hard. “Oh dear, I don’t understand what I wrote here.”

The whole dining hall laughed. Kaseki shook his head, tossing the papers to the floor and continued with his speech.

“Well, the only thing I know you all want me to say is when’s the next quidditch season going to start, and the answer it: two weeks from now!” The hall was filled with the student's roars, everyone excited at the news. Senku sighed and glanced over at the rest of the Ravenclaws that were sitting at his table.

He never went to the quidditch matches. He usually stayed at the Ravenclaw common room reading or studying at the library, enjoying the calm atmosphere of the castle when no one was around.

“Also, all the teachers are the same ones as last years, no changes. Am I forgetting something…?” He looked down at the crumpled papers on the floor and shrugged. “That’s all then. Hope you have fun. Let’s start with the Sorting Hat ceremony now.”

“I really was hoping for the Potions teacher to be changed this year.” Chrome pouted, staring at Mrs. Evans.

“She’s really good. The fact that she doesn’t like you isn’t enough to fire her.” Senku sighed, his eyes fixed on the first-year students that had gathered in front of the Sorting Hat.

“But I’m the best one at potions after you.” Chrome whined, pouting at the blond. “Well, now I’m going to be the third-best one, because with Gen Asagiri in class…”

The blond ignored the comment and paid attention to the Sorting Hat instead, hoping the ceremony could end quickly and he’d be able to go to bed fast.

 

———

 

The Sorting Hat ceremony had finally finished, and it was time for Senku’s favourite thing of Hogwarts: dinner.

He glanced back at his friend, who was munching at his food with his eyes fixed behind him.

“What are you looking at?” The blond asked.

“Gen Asagiri.” Chrome said with his mouth full, and Senku scowled. “Ukyo Saionji is sitting with him. A Hufflepuff sitting at the Slytherin table, have you ever heard of anything like that?”

Senku rolled his eyes. “If you keep looking at them like that, they’ll notice.” He turned his attention back to the food. He wasn’t fond of Hogwarts, but he definitely couldn’t deny that the food was the best he’d eaten ever in his life.

“I’m still that we are in the same class as Gen. I bet we’re going to get so many house points.” Chrome muttered, still looking at them.

“Gen isn’t even a Ravenclaw, how is it being in class with him going to give you house points?”

“You’re going to compete against him, aren’t you?” Chrome looked back at Senku, who had dropped his fork and knife at his words.

“What?”

“I know you,” He clicked his tongue. “You can’t stand being second in class.” He took another bite of his food, still looking at him. “And you’re a Ravenclaw, he isn’t. Intelligence is your main strength.”

“He was born to be a wizard, I wasn’t.” Senku reminded him, taking a bite of his food bitterly.

“Senku, don’t say those things. You’re here for a reason.” Chrome pouted, but the blond didn’t respond.

He turned around for a second to glance over at Gen and Ukyo, who were happily chatting over their food. He had seen him before on the hallways, but now he took his time to stop and really look at him.

Gen had his hair half-dyed black and white, making him stand out from the rest of Slytherins at the table. He was quite skinny, with sharp yet pretty features, his skin pale, and blue eyes so dark they almost looked black.

He smiled at Ukyo, and Senku turned back around.

Okay, maybe people were right about him being pretty.

“Studying your new opponent?” Chrome teased with a playful smile, and the blond sighed.

“Shut up.” He took another bite of his food, the image of Gen smiling still in his mind.

Chrome entered the room after taking a shower, only wearing his pyjama pants and a towel thrown over his shoulder.

“What are you doing?” He sat down on his bed, next to Senku’s, staring at the blond with curiosity.

“Reading.” Senku answered matter-of-factly, eyes fixed on the book. The brunet looked at the title and sighed.

Physics of the impossible? What could you possibly need to know about physics?” Chrome asked, meeting the blond’s gaze and frowning.

“I want to know even more about science.” He shrugged, and the brunet shook his head.

“For what? You can do anything with magic.”

“That’s not true.” Senku said, his eyes still fixed on the words in the book.

“It is! Tell me anything you can do with physics, and I’ll show you how magic can also do it.”

Senku sighed and put down the book, looking at his friend.

“Can you go to space with magic?”

Chrome stayed silent for a few seconds, then chuckled. “Why would you want to go to space? We have everything we need here.”

Senku sighed again and looked back at the book, ignoring him.

“Shouldn’t you focus on magic instead of on muggle science?” Chrome insisted, and the blond groaned before standing up.

“I’m going outside.” He said, putting on his shoes and a chunky sweater.

“Wait! Are you angry?” Chrome asked, standing up and following him to the common room.

“Yes, I am. Leave me alone.” Senku barked, exiting the common room with the book tightly gripped under his arm.

The Hogwarts hallways were totally empty. The Ravenclaw walked through the dark for a while until he found an empty classroom. He sneaked in and sat down at the windowsill.

The sky was clear, and the stars shone brightly against the dark blanket of the night. He mumbled all the constellation names he could see under his breath, pressing his forehead against the window.

“Why am I here?” He asked to himself, clutching the book tightly against his chest.

“Hello,” Gen greeted happily when he entered his room and found Tsukasa on the floor, doing some sit-ups.

“Hi, Gen.” The brunet grunted with a smile, not stopping his exercising.

“Already training for the quidditch season?” Gen sat down on the bed, staring at him.

“Hyoga and I have been training this whole summer.” He said, still not stopping. “This is our last year, so we have to make Slytherin win.”

Gen smiled and laid down on the bed with a sigh.

“So you’ve been together this summer?” He asked after a few minutes, Tsukasa’s soft pants the only thing filling the room.

“Yeah, we’ve been on Hyoga’s father’s cruise. We travelled the whole Mediterranean Sea before going to his mansion in Italy. It was crazy big. He even has a whole quidditch pitch there.”

“It must’ve been nice.” Gen sighed, staring at the ceiling.

“You can come next summer if you want.”

“It would be fun, but I can’t. Summertime is the only time I can work and save up money.”

“Gen,” Tsukasa sat up, looking at him. “You know that if you ever need any money, I can—” Before he could continue speaking, Gen stood up and faked a smile.

“I’m going to take a shower.”

“You don’t have to be ashamed about it.”

Gen turned around and glared at Tsukasa, who was staring at him with his eyebrows furrowed. “I’m not ashamed at all. I just don’t want to talk about it. Do you have a problem with that?”

Tsukasa shook his head tentatively, and before he could speak again Gen took his things and walked out of the room.

“Liberosis: the desire to care less about things, to stop overthinking and be insecure about your decisions.”

Dad,

You told me to write more frequently, although I don’t think I’ll end up sending you this letter.

It’s the first night after coming back here, and I already feel like going back home. Everyone is talking about quidditch and new magic spells they want to learn, and I’m here just thinking about how bad I want to be training with you so we could go to space together.

I remember when I got the acceptance letter. You told me I’d be the most intelligent and popular wizard to ever step foot in Hogwarts and here we are now. I’m alone in a classroom at the odd hours of the night because I argued with Chrome, one of my only friends here.

Should I even try to fit in? Does anyone else here have a passion for something, a life-long dream that isn’t even related to magic?

The only answer I have is that I should stop overthinking and actually start working hard to pass all the exams and get out of here as soon as possible. Once I do that, I’ll be able to dedicate all my time to science.

Yeah, I’m definitely not sending you this letter. The definition I wrote at the beginning is way too cheesy.

Love you,

Senku.

“Missed me?”

Gen stopped right before bumping into Ryusui, who had just appeared in front of him out of nowhere.

“Hello, Ryusui.” Gen greeted, dodging him and walking up the stairs. The blond followed him.

“Do you know that we’re in the same class this year?” Ryusui asked with a smile, staring at him.

Gen stopped for a second and glanced down at the paper he was holding, checking what class they had now. He started walking again with a sigh, still being followed by the blond.

“Now that we’re in the same class, you can tutor me.”

“I won’t.” Gen said, although he slowed his pace to let Ryusui walk alongside him.

“Come on, Gen. I want to get better grades, and I want you to help me with that.” Ryusui begged, looking at the Slytherin with a dramatic pout.

“I don’t have time to be tutoring you. Why don’t you just try and study for once in your life and see how that goes?” Gen answered with a fake smile, and Ryusui barked a laugh.

“I’ll pay you as much as you want. I won’t complain, even if you charge me a hundred for each class.”

“Still no.” Gen said before smiling at some girls that were waving at him. And now they were murmuring about Ryusui and him. Great.

“Please, Gen. Do you want me to give you all the money I have right now? I’ll do anything.”

“Why don’t you just find some other tutor?” The Slytherin asked, turning his attention back to the blond.

“Why would I settle for a mediocre tutor? I want you.”

Gen sighed at that, softly shaking his head in disbelief.

They finally arrived to the classroom. Gen entered the room followed by Ryusui and instantly walked towards Ukyo, who was chatting with Kohaku.

He sat down next to his friend and groaned when Ryusui sat down next to Kohaku, right behind him.

“Come on Gen. Name a price, and I’ll take it.” He whispered to him, and Ukyo chuckled.

“Is he trying to convince you to be his tutor again?” He asked, and Gen nodded, ignoring Ryusui and opening his Transfigurations book.

“If he doesn’t pass all his classes, they won’t let him play quidditch.” Kohaku tried, but Gen didn’t miss the way Ryusui slipped a 20-pound bill under the table for her.

“I don’t care. That’s his problem, not mine.”

Ryusui gasped dramatically, pressing a hand to his heart. “You really do belong in Slytherin.” Ukyo and Kohaku chuckled at the display. “Evil, evil people! Gen, I’m heartbroken now.”

“So sorry to hear that.” Gen tried his best not to smile, and before Ryusui could try and bribe him with something else, a group of three boys and a girl entered the classroom.

Gen kept his attention in the Transfigurations book, trying to ignore their glances.

“One lesson, Gen. I’m only asking for one lesson.” Ryusui whispered, and he turned to glare at him.

“What do you need a lesson now for? The school year has just started.”

“I need to refresh my memory.” The blond grinned. “I think that if we start with second-year stuff on I’ll be okay.” Kohaku and Ukyo chuckled softly, and Gen shook his head.

“Find another tutor.”

 

———

 

It was awkward.

The class had automatically divided into two. On the left side sat Gen, Ukyo, Kohaku and Ryusui, and on the right side were Senku, Chrome, Taiju and Yuzuriha.

The professor was explaining something about the O.W.Ls, but Senku couldn’t concentrate.

Chrome’s gaze on Gen was getting him on his nerves.

Stop looking at him.” Senku whispered, his gaze fixed on the professor.

“Do you think I could tutor Ryusui? How much would he pay me?” Chrome whispered back, and the blond sighed.

“Were you really listening to their conversation? Senku asked, looking at Chrome. The brunet blushed but didn’t answer, turning his attention back to the professor.

 

———

 

“So it was true.” Yuzuriha asked once they got out of class and found a bunch of students waiting for Gen in the hallway.

“It was so boring.” Chrome whined. “He didn’t say a thing.”

“He’s not here to entertain you, Chrome.” Senku sighed, making his way through all the students gathered there while looking up where their next class was.

“Oh, will you shut up already.” Gen’s voice startled them, the four of them turning back and finding the Slytherin smiling at Ryusui, who was waving a 20-pound bill on his face.

“Do you think they’re together?” Yuzuriha asked in a whisper, following Senku towards their next class.

“Isn’t he attracted to girls? He went to the dance with a fourth-year girl last winter.” Taiju muttered, looking back one last time at Gen and Ryusui before they turned left and lost sight of them.

“I’ve heard rumours that he’s been with boys too.” Yuzuriha shrugged.

Senku didn’t really want to listen to the gossip, but he couldn’t help but stop walking as fast, letting them catch up to him.

“I think the rumours about him being with boys are fake. I know too many girls he has flirted with.” Chrome observed, and the blond sighed, shaking his head.

“Why don’t you just stop talking about him? Leave the poor boy alone.”

“Ha!” Taiju barked a laugh, jumping in his way and making him stop. “Are you jealous because he has more game than you do?”

Senku frowned, glaring at his friend. “That’s the stupidest question you’ve asked in your life.”

 

———

 

“The weather is so nice.” Gen sighed, lying down on the grass and closing his eyes. He felt Ukyo lie down next to him after a few seconds, the Hufflepuff sighing at the feeling too.

They stayed like that for a few minutes, silently enjoying the sun on their faces and the soft breeze caressing their skin.

“Why didn’t you say yes to tutoring Ryusui? You need the money.” His friend asked, and Gen sat up immediately, looking down at him.

“I don’t want to get money from tutoring a rich kid who doesn’t understand the value of money.”

Ukyo stared at him for a few seconds before sighing and closing his eyes again. He knew it was fruitless to argue with Gen. “You could still charge him a normal amount for each lesson, you know.”

The Slytherin ignored the comment and lied back down.

“Do you know the two Hufflepuffs that are in our class?” He asked after a few minutes in silence.

“I’ve seen them around, I think. Their faces are familiar.”

Before Gen could ask who the blond Ravenclaw that had been with them was, Ukyo looked up at someone and waved.

“Hello! Come, come!”

Gen sat up and turned around. They were the two Hufflepuffs they had been talking about.

“Hi!” The girl said with a warm smile, sitting down in front of them. The boy sat down next to her, smiling shyly. “I’m Yuzuriha, this is Taiju.” Gen and Ukyo nodded.

“We already know your names, so no need to introduce yourselves.” The boy names Taiju mumbles, and Yuzuriha glared at him. Ukyo chuckled, looking back at Gen, who was fiddling with a strand of grass.

Yuzuriha cleared her throat. “We— Um… We were looking for the Hufflepuff quidditch captain. Do you know who they are?” She glanced at Ukyo, who pursed his lips and shook his head.

“I think they changed it this year, I’m not sure.”

“Oh, okay. Thank you anyways.” They stood up, and Taiju started walking back up the hill. Yuzuriha turned around to look at them one last time. “I’m happy we are in class together,” Her smile was warm, making her eyes crinkle. “I hope we all get to be friends.”

The two boys smiled at her before she turned around and followed Taiju away.

“And the two Ravenclaws that were with them in class before?” Gen asked once she was far away enough not to hear them, turning back to his friend.

“I don’t know them.” Ukyo shrugged before lying back down.

“I wonder if they’re good.” Gen muttered, lying down too and closing his eyes.

“Not better than you, don’t worry about that.” The Hufflepuff teased, and Gen elbowed him softly, chuckling.

“Idiot.”

 

———

 

“Ukyo sat down with us at the table today.” Taiju whispered, hugging his legs and resting his chin on his knees. Senku stopped reading to glance at him.

“That’s good.”

“I guess. He’s nice.” He mumbled, and Senku continued reading.

They were both sitting on a bench in a random hallway, an oil lamp lit up between them just so Senku could read. Otherwise, everything was pitch black.

“Don’t you have to go to sleep?” The blond asked, looking at Taiju again. His friend closed his eyes and sighed.

“I’ve been invited into the quidditch team.”

Senku closed the book and left it on his side, focusing all his attention on the Hufflepuff.

“That’s good news, isn’t it? Aren’t you happy?”

“I haven’t played quidditch ever before.” Taiju whined, worried.

The blond patted his back, trying to comfort him. “That’s what training is for.” His friend shrugged. “I’m sure you’ll be good at it. You’re great at flying.”

“But I don’t want to be a beater. I’m scared I’ll hurt someone.”

“Don’t worry about that. You’ll get the hang of it fast.” He insisted, grinning at Taiju when he turned to look at him.

“…Do you really believe that?” He asked, but before Senku could respond, someone stepped right in front of them.

Gen Asagiri.

“Oh, you startled me. I thought you were some professor ready to punish me.” The boy said with an innocent smile, and Senku eyed him sceptically. He was holding a book and wasn’t wearing any shoes, as if he didn’t want anyone to hear his steps.

“It’s fine, just us.” Taiju answered with a smile.

“Sorry to interrupt whatever you were talking about.” He apologised, smiling shyly. “I’ll go back to my room now.” Gen glanced at Senku one last time before disappearing again.

“He’s weird.” Taiju mumbled, eyes lost on the darkness where the boy had just walked into. “I bet you two would be amazing friends.”

“I guess that’s your cue to go to sleep too.” Senku said, taking the book and opening it again.

“Yours too. I’m worried about your sleeping schedule.”

“What’s a sleeping schedule?” He said jokingly, and Taiju shook his head, elbowing his side softly.

“You’re unbelievable.”

Chapter Text

Gen took a deep breath before hurrying towards Mrs. Geach, the flying professor.

“Good morning,” He said with a smile. Mrs. Geach looked up at him and mirrored his smile, her warm yellow eyes closing.

“How are you?” She rested her hand on Gen’s shoulder.

The boy smiled and turned around for a second, making sure no one was close enough to overhear their conversation. “I’m fine, thanks for asking.” He answered, still smiling when he turned back around. “Though I was wondering if I could just observe the classes instead of actively participating…”

Mrs. Geach sighed and crossed her arms, glancing down at him. “Are you still afraid of flying?” The Slytherin felt his face blush, and he looked away sheepish.

“Well, I wouldn’t say I’m afraid of flying per se, I’m afraid of dying because I fell off a broomstick.” Mrs. Geach shook her head and looked around the students that had gathered on one side of the field, patiently waiting for her to start the class.

“Kohaku!” The blonde girl turned to them. “Come, come here, darling.” The Gryffindor walked up to them, and glanced at Gen confused. “Could you please teach Gen how to fly on your free time? I’ll count it as extra credit.” Kohaku looked back at Gen, who was wildly blushing, and smirked teasingly.

“You don’t know how to fly?”

“Don’t laugh.” The Slytherin mumbled, and Mrs. Geach chuckled.

“What do you think they’re talking about?” Chrome whispered to Senku, who was staring at the professor and two students talking.

Senku sighed. “I don’t know, and I also don’t care.” He turned his attention to his broomstick.

“…Is he not going to attend these classes?” Chrome asked confused when he saw Gen walk away.

“Maybe he has something else to do.” Yuzuriha shrugged, glancing over at Ryusui, Ukyo and Kohaku, who were now chatting and laughing together.

“I wish I could also skip Flying.” The brunet Ravenclaw whined. “We’re here with two of the best quidditch players, you know.”

“I don’t know if you can really show off that much at flying anyways…” Senku’s voice trailed off when he saw Kohaku and Ryusui take a hold of their broomsticks and start chasing each other at incredible speed. They were chasing each other, evading posts and turning abruptly with ease, as if they had absolute control of the broomstick.

“And I’m supposed to play against them?!” Taiju whined, his eyes following how Kohaku flew.

“She’s the Gryffindor seeker, it’s expected for her to be so fast.” Yuzuriha was staring at the girl open-mouthed, mesmerised.

“And Ryusui?” Taiju asked, glancing back at the blond boy, who didn’t fly as fast as Kohaku but showed great control of his flying direction and speed.

“He’s a chaser.” Chrome answered, also staring at him.

“Oh god,” Taiju dropped down on the grass dramatically. “I’m doomed.”

 

———

 

It was almost midnight. The hallways were empty and dark. Senku was the first one to go up the staircase that led to the last floor of the tower, followed by Chrome, Yuzuriha and Taiju.

“Hello,” Ukyo greeted them with a smile when he saw them. Senku looked over at him and then at Gen, who was sitting down on the floor next to the blond.

“Why is everyone late today?” Yuzuriha asked, sitting down next to Ukyo. Taiju leaned back on the wall, munching on an apple. Senku stood on the middle of the room and looked up at the sky. It was a clear night, and all the stars could be seen perfectly.

“I don’t know. I guess dinner was too good and everyone stayed later than usual.” Ukyo said, lightly elbowing Gen, who had been staring at Senku for so long that even Chrome had noticed it.

Mr. Pargan rushed up the stairs panting, and looked around the room.

“Where are the rest?” He sighed when everyone shrugged. “Okay, then I’ll guess we’ll start without them. We don’t have much time left anyways.” He gestured for all of them to gather in the middle of the room. They all looked up at the sky. “Can someone tell me which constellation that one—?” Before he could finish the question, two students raised their hands.

Gen and Senku glared at each other for a second, their hands raised over their heads, before looking back at the professor.

“Oh, this is going to be interesting.” Ukyo murmured to Yuzuriha, crossing his arms over his chest with an amused smile.

 

———

 

“That was amazing. I’ve never seen you sweat over a classmate.” Ukyo grinned, elbowing Gen on the side softly. The boy grunted and started walking even faster, ignoring his friend. “Are you angry because you aren’t the most intelligent one in Astronomy now?”

Gen turned around and glared at Ukyo. “You should be on my side here.”

The blond grinned. “Why? Seeing you lose for once was quite satisfactory.”

“Mr. Pargan started asking muggle science things.” Gen sighed, turning around and starting to walk again. “What did he expect us to know about muggle science? I haven’t even read a thing about it.”

“Senku did know every detail.” Ukyo teased, and his smile broadened when Gen’s whole body tensed with annoyance.

“Sorry for not knowing how far away from Earth some stars are, we’ve never studied that.” Gen spat, angry.

Ukyo chuckled and the Slytherin turned around to glare at him again.

“This is going to be what everyone talks about tomorrow. The most popular Slytherin versus a really intelligent Ravenclaw, who will win?” Ukyo teased even more, and Gen had to make use of all his willpower not to slap his friend. He sighed and pressed the heel of his hands against his temples.

“I’m going to sleep. Thanks for nothing, best friend.” Ukyo chuckled and ran to hug Gen. The Slytherin dodged him with a swift jump and started running down the hallway, chased by Ukyo.

“Come here, give me a hug!”

“You don’t deserve it!” Gen exclaimed, dodging him again. He leaned against the wall, feeling out of breath. Ukyo took that as an opportunity to walk up to him with his arms wide open, ready to hug him.

“Give me a hug.” The blond repeated with a pout, and even though Gen shook his head stubbornly, he didn’t back away when the Hufflepuff wrapped his arms around him. Instead, he sighed loudly and hugged him back. “It’s okay not to be the best one at something.” Ukyo whispered.

“I know. I’m still going to crush him in all the other subjects, though.”

“Except Flying.” Ukyo said with a smile, and Gen pushed him away.

“I hate you.”

 

———

 

“That. Was. So. Cool.” Chrome beamed, sitting down on Senku’s bed, looking at him with his eyes wide open, shining with excitement. “How did you know all those things?”

“Science.” Senku said without tearing his gaze away from the book he was reading.

“Could you show me some?” The brunet asked, leaning towards Senku’s face. The blond frowned at him, and closed the book.

“I can’t show you science. It’s everywhere around you.”

Chrome stared at him for a few seconds, slightly tilting his head to the right, like a confused puppy.

“How can it be everywhere? It’s impossible.”

“The bed we’re sitting on right now is standing because of science. This whole castle is standing because of science.”

Chrome chuckled and shook his head. “That’s impossible. Everything here is made with magic.”

“Some of it, yes. The way the stairs move and doors appear out of nowhere is magic, but the answer to how this tower is being supported right now without falling is science. Someone has studied and calculated how to construct it in the most efficient yet stable way. That’s not magic.” Senku explained, but before Chrome could ask anything else, some second-year students entered the room. They stared at the blond with their eyes wide open.

“…Do you need anything?” The brunet asked, getting annoyed by their gazes.

“Are you Senku? The one who competed against Gen Asagiri?”

Senku sighed and laid down on the bed. News really did spread fast at Hogwarts.

“Ugh, just go away.” He groaned. The students started murmuring and after a few seconds they walked out of the room, closing the door behind them.

Chrome grabbed the blond’s shoulders and shook him. “Senku, teach me science. I want to be popular like you.” He asked with an enthusiastic smile.

“I think you should just stick to magic.” Senku said, leaving the book on the bedside table and turning the light off.

“Please.” Chrome whispered, standing up and lying down on his own bed.

“Sleep.”

Chapter Text

Gen was talking with a bunch of people that had gathered in front of the Slytherin house entrance to “comfort” him for what had happened yesterday. He really wanted to tell them he had slept fantastically, and it really wasn’t that deep, but they wouldn’t listen anyways.

“I’m fine, really.” He repeated for the fifth time while he walked towards the Great Hall, followed by everyone.

“Are you sure?” A girl asked him, and Gen smiled ready to answer when he felt someone throw their arm over his shoulder.

“Girls, I’m going to borrow him from you for a bit. Don’t panic.” Kohaku grinned, grabbing Gen and dragging him into an empty classroom.

“What do you want?” Gen asked as soon as Kohaku closed the door behind him.

She leaned against the door casually. “At what time do you want our flying class to start?” She asked, leaning against the door.

Gen’s face suddenly lost all colour. Kohaku frowned at him, confused.

“…Can we postpone it to another day?” He asked.

“On a scale of one to ten, how afraid of flying are you?”

“A hundred.” Gen glared at her when he heard her chuckle.

Kohaku pressed her lips together, trying to hold her laughter. “Sorry, sorry. We could start with something less difficult for you.”

“Like what?”

“Let me think about it. Come to the quidditch pitch at 5 pm.” Gen nodded, feeling a bit more relaxed. “Let’s go.” Kohaku opened the classroom door and walked out, followed by the Slytherin.

He bumped into someone once he walked out, and instantly back.

“So—…” His voice trailed off when he saw who it was. “…rry.”

Senku looked at him for a few seconds and after walking around him he continued his way towards the Great Hall.

“Sorry, he’s in a bad mood.” Chrome sighed, glaring at Senku and then looking over at Kohaku.

“What did I miss yesterday?” The blonde girl asked with an amused smile, looking at Gen and then at Chrome. The brunet looked at the Slytherin biting his bottom lip, as if he didn’t want to be the one to say it.

“Senku knows more about Astronomy than I do. Really, it’s not as amazing as everyone is saying it is.” Gen sighed, looking at the blond Ravenclaw, that walked a few meters ahead of them.

“It really was amazing.” Chrome said, and Kohaku smiled.

“I can’t believe I missed that. How does it feel to lose for once?”

Gen glared at her, and tried his best to smile without it seeming forced.

“It feels great, actually. I feel great.” He looked back at Senku and clenched his jaw. “I feel more energised than before.”

“I’m sure you do.” Kohaku mused, smiling at his reaction.

 

———

 

“How are you feeling?” Ukyo asked Gen while they were walking towards Kohaku, who was waiting for them with her broomstick laying on the grass.

“I think I’m going to puke.”

Ukyo laughed hard and gave him a pat on the back. “Everything’s going to go fine.”

“I’m not so sure about that.” Gen sighed before walking up to Kohaku. Ukyo winked at the Gryffindor before walking back to the castle, leaving the two alone.

“We are going to fly for a bit. Is that okay?” She asked, and Gen instantly stepped back.

“Absolutely not.”

“Come on, I won’t go too high.” The Slytherin shook his head, and Kohaku sighed. “I can’t teach you how to fly if you’re unwilling to sit on a broomstick.”

“I can sit on a broomstick, I just can’t fly on it.” Gen corrected, and she sighed again.

“How have you managed to skip Flying class all these years?”

“This is embarrassing.” He looked away, blushing. “I begged Kaseki to convince Mrs. Geach to let me go without flying. He said he’d do it if I helped him with his crafts, so I did.”

Kohaku frowned. “…Crafts?”

“Yeah, like… He likes to make things? For example, once he made me help him construct a real-life sized catapult. He also likes racewalking, so I accompany him sometimes.”

Kohaku stared at him for a few seconds before she burst out laughing. She rested her hands on her knees, unable to breathe.

“Racewalking?!” She exclaimed, still laughing.

Gen chuckled, blushing even more. “Stop. It’s not funny, poor old man.”

“Oh my god. Kaseki racewalking is something I want to see at least once before I die.” She wiped away a tear, still laughing. “How many people don’t know this?”

“That I don’t fly? I suppose everyone does. Why I’m not forced to attend the classes is a secret, though.”

“Then you’re not going to fly with me today?”

“Absolutely not.”

“What about just sitting on the broomstick?”

“No.”

“Please?”

“No.”

 

———

 

Senku didn’t know if he was the most loved or most hated Ravenclaw right now. Almost everyone was on Gen’s side, which was obvious because he was the most popular of them, but his housemates were quite proud that someone could compete against Gen in terms of knowledge.

Because it really had turned into a competition.

Most of the professors didn’t follow their game, but it all came down to how many answers each one could give in a class, or how many praises they could get.

Every class was always as entertaining as a film for both sides. Ryusui and Kohaku had made a bet against Taiju and Yuzuriha, each one on their friend’s sides.

“If Senku finds out about this he’s going to kill you both.” Chrome whispered to Yuzuriha when he saw her gesturing to Ryusui that she was going to win.

Senku, did, in fact, know that his friends were betting on who was going to “win” in each class, but he didn’t really care.

The only thing he cared about was that he wasn’t invisible anymore. Everyone looked at him and talked about him. They even asked Chrome whether he was single.

“You’re so popular now, Senku. Are you happy?” Taiju asked, patting his friend on the back.

“No.” He answered, although he was lying. Maybe this was one of the first time he really felt happy at Hogwarts.

And it wasn’t because he was popular now, but because seeing Gen so pissed off gave him huge amounts of satisfaction.

These last few weeks he had even memorised the way Gen reacted every time Senku raised his hand in class. He’d freeze for a second, look forward, clench his jaw, exhale heavily through his nose and then observe the teacher, waiting for them to pick him instead of the Ravenclaw.

“Then why are you smiling?” Yuzuriha asked, bringing Senku back to reality.

“I’m not smiling.” The blond said, lowering his head.

“You are.”

“I’m not.”

Chapter Text

The whole building was silent. All the students were gathered on the quidditch pitch, where the first match of the season was taking place.

Senku walked into the library, which was completely empty, and walked between the filled bookshelves towards his favourite reading nook. It was located on the far right side, a lonely table and two sofas where nobody normally sat. It was also the “books in ancient languages” section, so nobody really wandered there in search of books.

He turned right, almost there, when he saw a stack of books on the table and someone sitting on one of the sofas. He abruptly stopped when he recognised him.

Gen.

Senku instantly hid behind the bookshelf, hoping that the Slytherin hadn’t noticed his presence.

He looked between the books, taking a glimpse of what he was doing. His legs were folded against his chest and his feet were resting on the edge of the sofa. A book was balanced on his knees, and he had his arms wrapped against a cushion.

Senku had two options: he could go there and sit on the other sofa just to annoy him, or he could find another place to sit on.

He stared at Gen for a few seconds. The Slytherin was biting a pen while he read, deeply concentrated. The blond sighed and walked away from there, not wanting to disturb him. He wouldn’t be able to concentrate near him anyways, so it was better if he just ignored him.

Gen had noticed Senku before he had hidden behind the bookshelf, but he didn’t want the Ravenclaw to know he had seen him.

Part of him had wanted for the blond to sit and chat with him for the first time in their lives, ut his competitive side just wanted to be alone so he could study enough to surpass him in their classes.

It was strange. He had started by hating him, but these last few weeks his first priority when going to class was getting his attention to piss him off. If he didn’t get a glance, or at least a little “tch” every time he responded something correctly, Gen would get in a sulky mood until the next class.

Maybe he had just slipped into a routine without even realising: wake up, have breakfast, go to class and annoy Senku as much as possible, spend an hour with Kohaku (he still wasn’t able to sit on the broomstick), go to the library to study until one or two am, go to sleep, and repeat.

Still, he didn’t want to break out of it.

And he secretly hoped for Senku to feel the same.

 

———

 

Gen closed the book and sighed. He stretched his body lazily, feeling sore after being sat on the same position for hours, and stood up. It was almost one am, and he really needed to sleep.

He took all the books and after stuffing them inside his backpack he walked out of the library.

The hallways were dark, except for the moonlight entering through the windows. Gen looked out of the window, but the moon was so bright he couldn’t really see the stars. He sighed and turned around, ready to keep walking towards the Slytherin house when he saw someone at the end of the hallway.

“Hello?” Gen squinted his eyes, trying to see who they were.

He blinked and suddenly the person was closer to him.

But they weren’t a person at all.

It was the ghost of a woman.

Hogwarts was filled with them, so it wasn’t that rare to see one of them at night, but what scared Gen the most was how she looked.

Her face was pale and drained, with really pronounced cheekbones and really dark circles under her eyes. Her hair was almost gone, with only some strands falling on the sides of her face and giving her an even scarier look.

But that wasn’t even the scariest part. Her dress was torn, showing her stomach.

Or, really, what little was left of it, because her intestines were hanging out. When she took a step towards Gen, some of them dragged on the floor, leaving a trail of blood.

The Slytherin was feeling like he was going to faint at any given second now. He stepped back, clutching his backpack to his chest tightly, and before the ghost could get closer he turned around and started running away from her.

He rushed back to the library and collapsed on the very same sofa where he had been studying for the whole afternoon.

Gen closed his eyes, trying to calm down the wild beating of his heart, but the image of the ghost couldn’t leave his mind.

He sighed and hugged his backpack even tighter, his whole body shaking.

“What should I do now?” He whispered to himself, panicking.

Chapter Text

Ukyo shook Gen’s shoulders, waking up his friend.

“Gen!”

The Slytherin opened his eyes a bit, and instantly grabbed the blond’s wrist when he realised who he was.

“Everyone was looking for you. How did you manage to fall asleep here?”

“I saw a ghost yesterday.” Gen blurted, his eyes wide open.

Ukyo stared at him for a few seconds, a deep frown settling in his face. “…Okay?”

“No, you don’t understand. All her intestines were dragging through the floor and she looked like she hadn’t eaten in centuries.”

“Did you have a fever yesterday?” He pressed the back of his hand against Gen’s forehead.

“No, idiot. I really did see her. It was so scary I ran back here. I suppose I fell asleep later.”

Ukyo held the Slytherin’s gaze for a few seconds, his hand still resting on his forehead, before talking again.

“Should we warn Kaseki?”

“About a ghost in Hogwarts?” Gen chuckled, and shook his head. He loosened his grip on Ukyo’s wrist.

“She could scare a first year, or someone else. If would be even worse of them.”

Gen sighed and stood up. “What time is it?”

“Seven am.”

“Okay,” He brushed his hair away from his face. “I’ll talk to Kaseki later. I need to take a shower.”

“I’ll go tell everyone I found you.” Ukyo muttered.

Gen grabbed his backpack and followed Ukyo out of the library. “How many people are searching for me?”

“All the Slytherins and our class.”

He couldn’t help but perk up at that information, the curiosity making him speak. “Senku too?”

Ukyo turned around and smirked at Gen, who had started to blush a bit. He raised his eyebrows, amused. “Yes, Senku too. Why do you ask?”

“Nothing in particular.” He shrugged. The Hufflepuff’s smile only grew bigger.

“Sure.”

 

———

 

“So, you saw a ghost.” Kaseki repeated, his arms folded and his eyes on Gen, who had been pacing back and forth in his office.

“Yes.” The Slytherin answered, stopping and turning to the Hogwarts headmaster.

“And it scared you.”

“Quite a bit.”

Kaseki nodded, his lips pursed in concentration. “Okay. You can go now.”

“No— You don’t understand. She could frighten a younger student, or even attack someone.” Gen rested his hand on the headmaster’s desk, looking at him with pleading eyes.

“Did she seem aggressive?”

“Well, no, but…” Kaseki clicked his tongue and stood up.

“Fantastic. Everything is settled then.” He walked around his desk and gently pushed Gen towards the door.

“But what if she needs something?” The Slytherin asked, trying to stop Kaseki from pushing him out.

“Well, she’ll eventually find it.” The headmaster said, standing upright and not pushing Gen anymore. “My grandpa came back to haunt me because he’d been buried with his underwear inside out. It was quite embarrassing.” He chuckled, and lightly shook his head. “Anyways, you shouldn’t worry about it. If you ever see her again, tell me, although I doubt you will.”

“But—” Before Gen could say anything else, Kaseki pushed him out of his office and closed the door. “Fine,” He sighed before turning around and walking away.

 

———

 

“You were looking for me?” Gen asked, dropping down on the sofa in front of Senku.

The blond looked up from his textbook and glared at him. “Everyone else was.” He answered in a monotone voice, which made the Slytherin smile.

“Are you sure?” Weren’t you looking for me because you wanted to tell me that I really am the most intelligent wizard in Hogwarts and that you give up?” He swung his legs over the armrest, smug, and looked back at the blond.

“No. It’s quite self-centered of you to think you’re the most intelligent one here. You just study enough to surpass everyone else.” His voice still sounded monotonous, but his eyebrows were slightly furrowed. Gen smiled, pleased with getting a reaction out of him.

“Ouch, that hurt.” The Slytherin placed a hand over his chest dramatically. Senku sighed and turned his attention back to the textbook. “But were you worried for me? You must’ve wondered what you’d do if I, your nemesis, disappeared.”

The Ravenclaw looked up at him again, and huffed. “No.”

Gen pouted and tilted his head slightly. “You’re so boring.”

Senku ignored him and turned his attention back to his book. The Slytherin stared at him for a few seconds, and after sighing loudly he stood up.

“Going to your private flying lessons?” Gen turned around instantly and glared at the blond. Senku grinned at him, smug.

“If you laugh at me because of that I’ll kill you.”

The Ravenclaw’s smile grew wider, and he closed his textbook. “I really want to go to one of those classes sometime.”

“No.” Gen said instantly, feeling his face heat up.

“You’re so boring.” Senku mimicked him with a grin, and the Slytherin’s jaw tightened.

Still, he was enjoying this as much as the blond, who leaned back on the sofa and folded his arms.

“I’ll get back to you later.” Gen muttered after almost half a minute glaring at each other in silence.

Senku’s eyebrows shot up. “Can’t wait.”

Idiot.” Gen hissed before turning around and walking away from him. The blond stared at the Slytherin and grinned.

Pissing him off was turning into an addiction.

Chapter Text

“What if you help me with my homework in exchange for all the money I’m betting in your favour?” Ryusui wrapped his arms around Gen’s neck, pressing his chest against the Slytherin’s back.

“Good morning to you too, Ryusui.”

“Who is winning at the moment?” Ukyo asked.

“Well, today we have Astronomy class, so I’m sure Senku will get ahead of Gen.” Ryusui smiled when the Slytherin squirmed against his grip and manage to free himself from his hug.

“And why do you assume that?” Gen asked offended.

Ukyo grinned playfully. “Don’t get angry, but Senku is the master of Astronomy.”

“Maybe I should ask him to be my tutor.” Ryusui shrugged, and Gen huffed annoyed before turning around and walking towards their classroom.

“Oh, the baby got angry.” Ukyo cooed at him, following him into class and hugging his waist from behind.

“Get off me, you traitor.” The Slytherin said with a smile, trying to free himself from the blond’s grip. He finally managed to sit down on his chair, next to Ukyo. He glared at Ryusui, who had just leaned on Senku’s table. “Was he serious about Senku tutoring him?” He asked, looking at how the Ravenclaw was staring at Ryusui while he waved a 50-pound bill in front of his face.

“He couldn’t be a good tutor, though.” Kohaku muttered, sitting down behind Ukyo.

“Why do you say that?” Gen turned to look at her.

“He’s too interested in muggle science. I’d honestly love to see him on a wizard combat, showing how much power he truly has.”

Gen turned around and glanced at Senku again, who was still talking with Ryusui.

“But why are you refusing? I’d pay you more than enough for each class.” Ryusui pouted, making Senku sigh.

“I’m not a good teacher.”

“I just need someone to explain to me the basics of magic.” The Gryffindor begged. Chrome glanced up at Ryusui with a smile, entertained.

“I don’t know a think about the basics of magic.” Senku shrugged.

Ryusui chuckled and shook his head. “Now that’s a big lie. You are on the same level as Gen, so you’re as gifted of a wizard as he is.”

The Ravenclaw grinned up at him. “Am I?” He turned and glanced at Gen, who was still staring at them attentively. His smile got bigger, and the Slytherin looked away annoyed, making Senku smile even more.

Yes, now please tutor me.”

He looked back at Ryusui. “No. Ask Chrome.”

“I’ll do it, I’ll do it!” The other Ravenclaw volunteered, raising his hand.

Ryusui glanced at him and sighed. He completely ignored him, going back to sit at his chair, lightly slapping Kohaku’s arm when the blonde girl laughed at him.

 

———

 

“Come on, try to sit on the broomstick.” Kohaku sighed, grabbing Gen’s arm and lightly pulling.

“How can I know you won’t use a spell so it starts flying?” Gen asked, looking at her with his face slightly blushed in a mix of fear and embarrassment.

“I promise I won’t.” Kohaku pressed her hand to her chest, solemn.

The Slytherin sighed, staring at her for a few seconds, before turning around to get on the broomstick.

He was about to grab it when he noticed someone sitting on the grass, staring at them.

“You fucking leek hair!” Gen yelled, rapidly pacing towards Senku. Kohaku sighed, frustrated, but didn’t do anything to stop him.

Senku’s smile was smug. “Hello.” He leaned back on the grass, casual.

“Don’t you have studying to do for later?” Gen asked, resting his hands on his hips and looking down at him.

“Could you move a bit to the left? You’re blocking the sun.”

Gen tightened his jaw, making him smile even more. “Go away.”

“I want to watch you fly. You look cute all embarrassed and blushed like that.”

The Slytherin bit his bottom lip, trying to make use of all his willpower not to punch him, and sighed loudly.

“Go to the library, study a bit. You’ll need it.”

“Will I? The next class we have is Astronomy. I think you’re the one who needs to study.”

They stared at each other for a few long seconds, until Gen huffed and turned around. He grabbed his backpack and stomped away from Senku, towards the castle.

“Did you really have to come? He was almost going to sit on the broomstick.” Kohaku sighed, dropping down on the grass next to Senku.

“You were going to make it fly the second he sat down on it, weren’t you.”

The girl’s smile was devilish. “Of course.”

 

———

 

“Let’s leave it at that for today.” Mr. Pargan said, looking at his watch. The students nodded before getting their backpacks and walking down the stairs.

It was a chilly night. Everyone was wearing their house scarfs tightly wrapped around their necks, and couldn’t wait to get back to the warmth of their rooms.

Gen sighed before lying down on the floor, looking up at the sky. He stared at the constellations that could be seen that night when he felt someone lying down next to him.

“Does trying to outsmart me tire you that much?” Gen turned his head and glanced at Senku, whose eyes were fixed on the sky.

“Sen—” Before Chrome could call his friend, Ukyo covered his mouth with his hand.

“Let’s leave them alone.” The Hufflepuff whispered, dragging Chrome down the stairs, following everyone else.

“No, I actually think you’ve been a bit weak today. Are you feeling pity for me? Do you like me that much you’d leave your Ravenclaw pride aside?” Gen grinned cockily when Senku turned his head to look at him. He couldn’t really stand the blond’s gaze on him, not when they were so close, so he looked back up at the starry night.

“You wish.” Senku said after a brief silence.

“How do you know so much about astronomy anyways?” Gen asked after a few minutes without saying a thing.

Senku sighed and put his hands behind his head. “My father is training to be an astronaut.”

The Slytherin turned on his side to stare at the other, eyes wide open in surprise and curiosity. “I didn’t even know that was real. I thought it was made up by the muggle government.”

“Made up by the government? No.” He stayed silent for a few seconds, oblivious to the way Gen was observing the subtle way his chest raised and fell every time he breathed. “I also want to go to space.”

“Are you going to train for it once you finish here at Hogwarts?” Gen’s voice had softened almost into a whisper, and Senku was suddenly aware of the little space between them.

He kept his gaze fixed on the sky, trying to ignore the weight of the other’s gaze on him. “Most likely.”

“That’s so cool. I’d love to know how it feels out there.” Gen sighed, lying on his back again to look up at the moon.

Senku stared at the Slytherin for a few seconds, his eyes widened with surprise, and he hastily stood up. “I— I have to go now.” He said, taking his backpack and rushing down the stairs.

Gen sat up and watched him go away, his eyebrows furrowed in confusion. “Okay…?”

Chapter Text

Dad,

Yeah, I’m probably not going to send you this letter either, but I need to write my feelings down or I’ll combust.

It’s so weird to feel understood for the first time. It feels like a non-physical hug.

I hope you’re okay and happy.

Loves you,

Senku.

Chapter Text

“Where were you yesterday?” Chrome asked Senku while he followed him towards the entrance of the Forbidden Forest, where their first Care of Magical Creatures lesson of the year was taking place.

“I went to study.” Senku lied, and walked faster to catch up to Taiju and Yuzuriha, who was trying to calm down the brunet.

“Taiju, don’t worry so much about it. I’m sure it’ll go fine.” Yuzuriha patted his back.

“Are you nervous for your first quidditch match?” Senku put his arm around his friend’s shoulders.

Taiju sighed. “Slytherins frighten me.”

“Don’t worry, it’s their first match of the season, I’m sure they will go easy on you.” Yuzuriha tried to comfort him.

He nodded before turning towards the blond. “Senku, are you coming?”

“Of course. I won’t miss any of your matches.”

Taiju’s face lit up with excitement. “Really?!” The blond nodded with a smile.

When they finally arrived at the clearing, they found Ukyo petting one of the Hippogriffs while he talked to Gen, who was sitting down on the grass.

Yuzuriha and Taiju instantly walked towards Ukyo and Gen, and started conversing with them. Chrome stood awkwardly next to Senku.

“I don’t know how he pets it like it’s nothing. It could literally eat him.” The brunet muttered, looking at the Hippogriff with his eyebrows furrowed.

“I don’t think it would. It looks like it likes him quite a lot.” Senku observed, noticing the way the Hippogriff was rubbing his head against Ukyo’s back because the blond had stopped petting him in favour of talking to Yuzuriha.

“So are you going to the match today?” Chrome asked, switching the topic.

“Yeah, I promised Taiju. It’ll be my first quidditch match, too.”

“Is he going?” The brunet asked again, toying with a strand of grass absentmindedly. Senku looked away from Ukyo and the Hippogriff to stare back at his friend.

“Who?”

“Gen.” His friend’s eyes were fixed on the Slytherin, who was smiling at Taiju while the brunet enthusiastically talked to him about the upcoming match.

“Why would I know?”

“Well, yesterday—” Before Chrome could say anything else, Senku interrupted him.

“Let’s go pet the Hippogriff too, shall we?” He rushed away from Chrome, who stared at his friend’s back in confusion.

“When have you ever wanted to pet an animal?!”

 

———

 

“And Hufflepuff caught the Golden Snitch, summing 185 points and winning the match! Congratulations!” The commentator exclaimed, her voice soon drowned by the students’ roaring voices. Senku and Yuzuriha cheered as loud as they could, waving at Taiju frantically.

“That was long.” Senku shuddered, adjusting his scarf so it covered up to his nose. They had been sitting for three hours and he was freezing.

“I should hurry back to Hufflepuff,” Yuzuriha sighed, mimicking the blond and adjusting her scarf too. “I’m sure they’ll be celebrating.” She turned to Senku and Chrome with sad eyes. “I’m sorry you can’t come.”

They both shook their heads. “Don’t worry about it.” Chrome waved her off. They watched her hurry away alongside the rest of the Hufflepuffs before the brunet sighed deeply. “I need to sleep.”

“Me too. Let’s go back.” Senku muttered, making his way back to Hogwarts with Chrome alongside him.

They were the last ones to go back to the castle. It was almost pitch black, so they didn’t really recognise Ukyo and Gen until they were less than a meter away from them.

“We won, we won, we won.” Ukyo chanted on Gen’s ear, trying to annoy the Slytherin.

“Yeah, I was there, I saw that.” Gen sighed, pushing his friend away. Ukyo chuckled and turned around, finally seeing Chrome and Senku.

“Hey! Did you see that? Taiju was so good.” Ukyo stopped and waited for the two Ravenclaws to catch up to them.

“Yes, he has a natural talent.” Senku said with a smile, finally meeting Gen’s gaze. “How does it feel to lose?” He teased, and the Slytherin pursed his lips.

“Don’t you have any studying to do?” He asked annoyed. Ukyo and Chrome exchanged a glance before they started walking, leaving Gen and Senku alone once again.

“I was actually planning on sleeping for once.” The blond huffed, walking alongside Gen.

“You’re going to fall behind.” He teased.

Senku grinned. “If you think one night without studying is going to make me fall behind, you’re underestimating me.”

Gen chuckled and shook his head.

They entered the castle the four of them together, Chrome and Ukyo happily talking while Gen and Senku stayed silent.

“So… You’re not coming to the library?” The Slytherin asked, looking up at the blond.

Senku looked at him, trying to decide what he should do, when an owl landed on the windowsill with a letter on its beak. He walked up t it and carefully took the letter. It was from his father.

“Sorry, I have to read this.” He smiled, his face blushing, before turning around and rushing away from them.

Ukyo, Chrome and Gen stared at him walk away.

The Hufflepuff gave Gen a pat on the back. “I think you’re going to have to study alone for today.”

Chapter Text

Senku,

It’s funny how you always tell me you won’t send the letters and then end up doing it. I was really happy reading your last one.

It’s good that you’ve found someone that understands you, whatever that means. (I hope it’s not that someone finally has enough scientific knowledge to understand whatever you’re saying when you get carried away talking about an experiment. If that’s the case, I’m less happy because they managed to achieve something I never will.)

October is already ending and we’re training even harder every day. I’m still having a lot of fun though, so don’t worry about that.

I also wanted to write to you because I’ve just been informed I’m going to have to spend Christmas and New Years here. I’m sorry, but I’m afraid you’ll have to spend the holidays at Hogwarts. You can also stay at Chrome’s at Taiju’s, but that’s up to you. I’m sorry it has to be like this.

Take care and study a lot (and have fun).

Much love,

Byakuya.

 

Chapter Text

Gen yawned and closed the book. He rubbed his eyes and curled up on the sofa, resting his cheek on his knees. He sighed before standing up and taking his backpack.

The hallways were empty, but the lights were still turned on. He could hear the faint sound of voices, and guessed it was the Hufflepuffs, probably still celebrating their victory.

He turned left, finally seeing the Slytherin entrance when someone appeared in front of it.

Gen recognized her instantly. The ghost he’d seen some days ago was there again, her intestines still grotesquely hanging out of her.

“You again.” The Slytherin muttered, stepping back, his skin getting goosebumps and his hands slightly shaking. “May I help you with something, miss?” He clutched his backpack, scared, waiting for her to respond.

He realized then that her lips were sewn together, making it impossible for her to talk. Gen took another step back, but the ghost floated closer to him.

“I— I’m afraid I won’t be able to help you.” Gen’s voice wavered. The ghost tilted her head, staring at him attentively. “You— You should go find help somewhere else.” He took another step back when the ghost drifted towards him, her white and stained with blood dress swaying.

The last thing Gen saw before passing out was the ghost’s face inches away from his, her dark eyes studying him attentively and her sewn lips forming something similar to a macabre smile.

 

———

 

“Is he dead?” A young girl asked, looking down at Gen, who laid on the hallway floor hugging his backpack with his eyes tightly shut, his body still shaking.

“What kind of question is that? Of course not.”

Before someone else could talk, a student made his way through the crowd.

“Why are you all standing in the middle of the hallway? Make some way for the—” Tsukasa abruptly stopped when he arrived at the middle of the circle and saw his friend. “Gen?! Oh my god.” He pulled the boy in his arms, and turned to the other students. “He’s unconscious and you just stare at him instead of asking for help?! What kind of housemates are you?!” He yelled, making all the students step away scared. “Tell Hyoga I’m in the infirmary and that he should tell Ukyo to come.” They all nodded.

Tsukasa turned around and hurried away from them, holding Gen tightly in his arms.

 

———

 

The first thing Gen saw when he opened his eyes was Ukyo’s face inches from his. The blond smiled and wiggled his eyebrows.

“Hello, sleeping beauty.”

Gen sat up on the bed and massaged his temples. “Why am I at the infirmary?”

The Hufflepuff sat down on the bed next to him. “You passed out in the hallway. Don’t you remember?”

Gen blinked a few times until he recalled his encounter with the ghost yesterday. He groaned and hid his face in his hands.

“Ugh, I remember now.”

Ukyo rested his hands on his friend’s thigh, lightly squeezing it. “Did she attack you?” He asked, and Gen looked up at him.

“…I don’t think so. I only remember she walked up close to me and I fainted.

“Should we tell Kaseki?”

“No,” He sighed. “He won’t listen to me.”

Ukyo glanced at the infirmary door. “He’s awake now.”

That made Gen look towards the door too. Tsukasa was hurrying to him, pressing the back of his hand to his forehead as soon as he was close enough.

“Are you okay? Do you have a fever?”

“I’m fine, don’t worry.”

“You scared me for a second.” Tsukasa sighed, his shoulders relaxing. “What happened?”

“Nothing. I haven’t been sleeping enough, I guess.” Gen lied. His words made Tsukasa cross his arms, worried. “Don’t you have classes to attend to?” He asked before Tsukasa could scold him.

“Yes, I just wanted to check up on you one last time. Take care.” Tsukasa petted Gen’s head affectionately before turning around and leaving.

Ukyo frowned. “Why did you lie to him?”

He sighed, dropping back down on the bed. “It’s for the best.”

 

———

 

“Where’s Gen?” Yuzuriha asked Ukyo as soon as the class finished.

Senku stopped doodling on his book and closed it, paying attention to their conversation.

“He fainted yesterday night. Some students found him in the hallway this morning. He’s in the infirmary right now, but he’s fine.”

“Really? What happened exactly?” Ryusui asked, appearing behind Ukyo.

The blond waved a hand around, not giving it much importance. “He’s just not been sleeping enough, that’s all. No need to worry.”

“We should all go visit him after Charms.” Yuzuriha suggested, and everyone nodded.

“Yes.” Kohaku agreed. “We’ll go get some food for him.” She said before rushing out of the classroom, followed by Ryusui.

“You should also come, Senku.” Ukyo rested his hand on the blond’s shoulder.

“I don’t think bringing out his competitive side now it’s a good idea.” Senku said, rapidly putting his books inside his backpack and hurrying out of the classroom.

“Do you think—?” Yuzuriha started, watching Senku go away, but before she could finish Ukyo and Taiju talked in unison.

“Oh, absolutely.”

Chrome eyed them confused. “What are you all talking about? I don’t get it.” He asked, and everyone chuckled, making him frown. “Not funny, explain.”

 

———

 

Gen closed the book he was reading when he heard the infirmary door open, and smiled when he spotted Senku.

“Can’t stand a day without seeing me?” He asked with a smile. Senku walked up to his bed.

“I just wanted to make sure you hadn’t died before I had the opportunity of crushing you myself.” The Ravenclaw stood next to Gen’s bed, who had sat up and left the book next to him.

“Don’t worry, I’m alive and well. Just a little bit tired, that’s all.”

The blond realized the Slytherin was only wearing his uniform shirt with a few of the first buttons undone, showing his neck and collarbone.

He cleared his throat before looking back up at his face. “You’re so worried about winning that you aren’t sleeping enough?” He teased, and Gen smiled, hugging his legs and resting his cheek on his knees, looking at Senku.

“You wish.”

“…If you’re feeling better now, why are you still here?” Senku asked, sitting down on the bed next to Gen’s.

“They want to make sure I eat lunch and dinner.”

“Were you before?” The Ravenclaw stared at him.

Gen picked up his pillow and threw it at him. The other caught it with a smile. “Of course I was, idiot.”

Senku threw the pillow back at him. He took it and hugged it against his chest.

“…Was the letter you received yesterday from your father?” He asked after a few minutes in silence. The blond looked up at him and felt his face heat up a bit when his eyes met Gen’s. He nodded, looking away and fiddling with the bedsheets. “How is he?”

“He’s fine.” The Slytherin nodded, and Senku sighed. Before he could think about it twice, the words were coming out of his mouth. “I won’t be able to go back home for Christmas, though. He has to train.”

Gen widened his eyes in surprise and smiled. “Then I’m not going to be the only one who doesn’t go back home for Christmas this year.” He sighed in relief, lying back down on the bed.

The Ravenclaw stared at how Gen’s shirt had riled up, showing a bit of his stomach. He felt his cheeks warm up even more.

“You were spending Christmas here, alone?” He asked, forcing himself to look back at Gen’s face.

“Every year,” He sighed dramatically. “Do you know how boring it is to have dinner with Kaseki? He just talks about people I’m too young to have heard about.” They both chuckled, and Gen looked back at Senku.

Their gazes met, holding them for a few seconds, until the blond stood up, clearing his throat. “Will you come to class tomorrow?”

“Yes, don’t worry.” Gen sat up again. Senku nodded.

“Prepare yourself for defeat, then.” The blond said once he reached the infirmary door, not looking back at Gen.

He still could hear the smile on his face when he talked. “That only happens in your dreams.”

Chapter Text

Dad,

Don’t worry about me. I’ve spoken to a friend and we’re both staying here for Christmas. I needed that extra study time anyways.

Write soon,

Senku.

Chapter Text

Transfiguration had always been Gen’s favourite subject. He had been eagerly waiting to finish with all the theory part of the subject to finally be able to use magic.

But the thing he had been waiting for the most was seeing Senku finally using his wand. The blond Ravenclaw was good at memorising things, but he hadn’t seen him use any magic yet, and he was so curious he couldn’t tear his eyes off from him.

“What are you looking at?” Ukyo softly elbowed his friend, who glanced away from Senku.

“Have you ever seen Senku use magic?” Gen asked in a whisper.

His friend frowned. “…I have, actually. He can project a corporeal Patronus.” Ukyo smiled when he saw Gen’s eyes widen.

What?!” The Hufflepuff gestured him to not speak so loud, and Gen cleared his throat. “When did you see it?” He whispered.

“Last year.”

“So you knew it beforehand.” Ukyo grinned, and Gen slapped his shoulder softly.

“Of course I knew!”

“And you still didn’t warn me about him being as good as I am.” His friend winked, and Gen pointed his wand towards him. “Prepare to become a teapot.”

Ukyo chuckled and ducked, rapidly running to hide behind Ryusui.

“I’ll let you turn him into a teapot if you agree to tutor me.” Ryusui said.

Ukyo gasped dramatically. “You traitor!”

Kohaku chuckled, but before Gen could push Ryusui away to give the Hufflepuff his punishment, the professor walked up to them and cleared her throat.

“Everything okay?” Everyone turned around and looked at her.

“Yes, sorry, sorry.” Ukyo said blushing, turning back to his seat.

Gen felt his face heat up too, Senku’s gaze weighing on him.

“Now turn that cup into a teapot, please.”

The Slytherin glanced sideways and saw an impeccable teapot on Senku’s table. He tightened his jaw and with a light flick of his wand, he turned his own cup into a teapot too.

“Good. Now, add some decorations to the teapot. Whatever you want, but it has to be intricate enough to look like it was handmade.”

“We’ve been doing this for five years already. I’m bored.” Kohaku muttered.

“Shut up.” Ryusui said, still trying to turn his cup into a teapot. Gen and Ukyo chuckled, and the blond Gryffindor glared at them.

“I really don’t know how you’ve managed to pass every year.” Kohaku lightly shook her head, looking at her best friend with amusement.

“I said shut up!”

 

———

 

“You’re making me nervous.” Gen said, putting his book down and looking at Ukyo, who was playing target practice with a little archery bow toy.

He hit another book, dropping it to the floor, and smiled. “I told you I’d be with you 24/7 in case that ghost reappears.” He aimed for another book.

Gen sighed and with a flick of his want he took Ukyo’s bow. “Maybe if you studied with me.”

Ukyo rubbed his eyes and leaned back on the chair. “I’m not the one trying to get Senku’s attention, so I don’t need to study.”

The Slytherin shook his head, wildly blushing, and threw a book at Ukyo when he started laughing at him. “Shut up.” He turned his attention back to the book.

“It’s already midnight. Don’t you want to go back to sleep?” Ukyo asked after half an hour.

Gen closed the book with a sigh. “Okay, let’s go.”

The blond stood up excited, and helped Gen put all his books inside his backpack.

“I’ll accompany you to the Slytherin door.”

“I really need some alone time, you know.” Gen sighed, following Ukyo out of the library.

“Don’t lie, you love spending time with me.” The Hufflepuff put his arm around Gen’s shoulder, squeezing the other’s body against his.

Gen wrapped his arm around the blond’s waist. “You wish. When are you going to start practising archery again and leave me alone?”

“Never.” He smiled. The Slytherin was going to respond when he suddenly stopped. Ukyo looked at him confused. “What?”

There she was again.

The ghost was standing in the middle of the hallway, and Gen could’ve sworn she smiled when she saw him.

“Gen? Are you okay?” Ukyo asked, worried. The Slytherin noticed the tight grip he had on the blond’s arm, and he released it, stepping back.

“Look.” Gen whispered, and he tugged on the Hufflepuff’s sweatshirt when he saw the ghost step towards them.

“What are you doing!?” He turned back to his friend, then looked back at the empty hallway.

The ghost took another step towards them, and Gen tugged on Ukyo’s sweatshirt harder, making him tumble backwards.

“You can’t see her?!” Gen exclaimed.

“See who?!” Ukyo yelled.

 

———

 

Gen pushed the infirmary door shut and rested his back against it, panting.

Ukyo dropped down on the floor, his breath also short, looking up at his friend.

“I thought you were kidding at first.” The Hufflepuff said, breathless.

“Why would I be kidding?!” Gen slid down and sat on the floor, trying to catch his breath.

“Because I can’t see her.” He closed his eyes. The Slytherin lied down next to him, feeling the cold floor against his cheek. “What if she comes here?”

“She won’t. She didn’t follow me back to the library the first time.” Gen sighed and slowly sat up, finally able to breathe normally.

“We’ll have to spend the night here, then.” Ukyo said, also sitting up.

The other turned to look at him and smiled, raising his eyebrows. “You’re more scared than I am.”

“No, I’m not.” The Hufflepuff said instantly, standing up and walking over to the nearest bed. He dropped down on it. “What if she tries to kill you again and I’m not able to help because I can’t see her?”

Gen stood up and lied face down on the bed next to Ukyo’s. “Then you’d be a really bad best friend.”

The blond sighed again. “I’ll make sure to wake up before everyone else does so we have time to take a shower.” He said, taking off his tie and covering his body with the white sheets.

“…Why do you think I’m the only one who sees her?” Gen asked, looking at Ukyo. His friend sighed, gaze fixed on the high ceiling above them.

“No idea. But at least there’s something good about that.”

“What?”

“She can’t scare other students, only you.”

Gen propped himself up on his forearm, glaring at his friend. “Maybe the problem is yours and that’s why you can’t see her.”

The Hufflepuff chuckled and shook his head, closing his eyes. “I doubt it. Now sleep.”

“But—” Before Gen could complain Ukyo turned around, giving him his back.

“Sleep.”

The Slytherin sighed and lied back down on the bed, covering himself with the sheets and closing his eyes.

“Maybe she wants to marry me.” He joked after a few minutes in silence.

Gen.”

Chapter Text

“…You saw a ghost, he didn’t.” Kaseki repeated. Both Ukyo and Gen nodded, and the headmaster looked back at all the people that had gathered in the middle of the hallway. “And all of these students are…?”

“They’re just waiting to talk with Gen, ignore them.” Ukyo waved him off.

The headmaster looked back at them. “I really don’t see the problem. If no one else apart from you can see her, then it’s not really something we should worry about.”

“Are you holding some kind of grudge against me, Kaseki?” Gen rested his hand on his heart dramatically, making the headmaster chuckle.

“You know I don’t, but I’m really busy right now. Ministry problems.” He patted Gen’s hair, messing up his hair. “I have to go now.” He turned around and carelessly walked away.

Ukyo sighed, leaning against the wall and pinching the bridge of his nose. “It’s no use, you’ll have to research it yourself.” He turned when Gen didn’t respond to him, and spotted him in the middle of a circle of students, happily conversing with them. “Hey Gen, we’re going to be late!” He called.

“Yes, yes, coming!” Gen yelled back, but kept talking with a group of third-years.

Ukyo sighed and turned around, walking towards class. “Your problem.”

 

———

 

“I don’t know a thing about ghosts.” Kohaku shrugged.

“Me neither.” Ryusui leaned back on the chair, making Ukyo and Gen sigh.

“I’m doomed then. She’s going to kill me while I sleep.” The Slytherin rested his head on Ukyo’s shoulder, whining dramatically.

Ryusui clicked his tongue, deep in thought. “I could ask someone for help…” He grinned.

Gen leaned over the class table, staring at him. “Who?!”

The Gryffindor’s grin grew bigger. “In exchange for one lesson.” He said, his forehead almost touching Gen’s.

Kohaku rolled her eyes. “There he goes again.” She sighed, and started playing by making her Charms book elevate in the air with small flicks or her wand.

“…Okay. I’ll do it.” Gen said, still staring at Ryusui.

The blond flashed a huge smile, patting Gen’s head before leaning back on his seat again.

“Let’s wait for this class to end.”

Gen turned back around on his chair, finally feeling energised again.

“What do you think they’re talking about?” Taiju asked, Staring at Ryusui and Gen.

“Who?” Senku turned around, instantly seeing Ryusui’s face centimetres away from the Slytherin’s. He frowned and turned back around, staring down at his book.

“Why are they so close?” Chrome asked, frowning too.

Yuzuriha looked back at them. “You haven’t heard the rumours?”

Taiju and Chrome looked genuinely confused. Senku kept his eyes fixed on his book.

“What rumours?”

“That they’re dating.”

Senku sighed and flipped the pages of his book, trying to concentrate on the words written on the page to distract himself.

“You think so?”

“That’s what everyone’s saying, but I don’t know.” Yuzuriha shrugged. “I don’t really see them together much. Maybe they’re keeping it a secret.”

“I’ll ask Ukyo later.” Chrome muttered, sitting straight when he noticed the teacher enter the classroom. He still softly elbowed Senku on the side, making him look up. “What do you think?”

Senku turned back to his book, trying to keep his voice sounding as disinterested as possible.

“I don’t care.”

 

———

 

“So, who is the person you’re going to ask?” Gen sat down on the grass in front of Ryusui.

Kohaku tugged on Gen’s sleeve, trying to get his attention. “Aren’t you going to try and sit on the broomstick today?” She pouted at him.

Gen waved his hand around in dismissal. “Forget it.”

She groaned, trying down and resting her head on the Slytherin’s lap.

“Well,” Ryusui shrugged, smiling cockily. “I’ll obviously ask my favourite person in the whole world.”

“And that is…” Ukyo started, sitting down next to the blond Gryffindor.

“Francois, of course.” Kohaku answered for him.

Gen looked down at her, but before he could ask who Francois was, Ryusui took his mobile phone out of his pocket.

“What are you doing here with a phone?!” Ukyo exclaimed, looking around to make sure no one was close enough to see it.

Ryusui shrugged. “If I don’t have it I get bored.” He pressed the call button.

It only rang once before the person on the other line picked up. “Yes, master?” Francois responded instantly, making him smile.

“I need help with something. A ghost is causing a friend some trouble.”

“…Has the ghost harmed you in any way, master?”

Ukyo and Gen exchanged a look, confused.

“Not to me directly, but my friend—”

“Then I’m afraid I won’t be able to help you, master. Your father said I only could travel to Hogwarts in case you were in danger.” Francois hung up without any other word. Ryusui sighed and lied down on the grass.

“So your father does know about the time you called Francois to come and make us pancakes.” Kohaku chuckled.

“I guess he does.” He sighed again dramatically.

Gen pouted, sulking. “I’ll have to go research on the library then.” He sighed, gently pushing Kohaku off from his lap and standing up.

“Don’t stay until late.” Ukyo warned.

He took his backpack and smiled at him. “Don’t worry.” He walked away from them, ignoring all his friends’ gazes on him.

Kohaku propped herself up on her arm, looking at Ukyo.

“Aren’t you going with him?”

“No,” He shook his head. “I want him to run into Senku.”

“Senku?” Ryusui frowned. “Don’t they hate each other?”

Ukyo’s smile was devilish. “Give them some time.”

 

———

 

“Can I sit here?”

Senku looked up from his book, his gaze meeting Gen’s. He glanced at the empty sofa in front of him, and hesitantly nodded.

“Thanks.” Gen smiled before sitting down and opening his backpack, not noticing the way the blond was staring at him.

The Ravenclaw’s eyes were fixed on the way Gen was sitting, both feet resting on the edge of the sofa, the book balanced on his knees. He seemed very concentrated, softly biting his pencil.

Senku forced himself to look back at his book, but he still found himself staring at Gen sometimes. He sighed and tried his best to focus.

Gen was more concentrated on the other than on his read. He avoided the blond’s gaze when the other was staring at him, but stared at Senku whenever he had the chance.

After almost an hour without being able to read even a single sentence on the page, he sighed and stood up, leaving the book on the sofa. Senku looked up at him.

“I’m just going to search for a book. I’ll be right back.”

Gen was making his way towards the main desk when three fourth-year students approached him.

“Can we ask you something?” One of them asked, cheeks reddening with embarrassment.

The Slytherin tried to make his fake smile look genuine. “Yes, of course.”

Senku had noticed the exchange, carefully standing up and getting closer, hiding behind a bookshelf. He was close enough to overhear their conversation.

“Are you and Ryusui dating?” Another one of the students asked, eyes wide open in genuine curiosity.

Gen couldn’t help but snort. “Ryusui?! Oh god.” The students chuckled at his disgusted face. “No, we aren’t dating.”

Senku felt his whole body instantly relax. He turned around and took a book from the bookshelf, which obviously was the reason why he had gone there in the first place, then returned to the sofa.

The Slytherin arrived back after some time with a huge book in his hands and sat down again, eager to read it.

“Extra research?” Senku asked.

Gen looked up at him with a tight smile. “You could say that.”

“I could lend you some science books, you know. Maybe you’ll learn something new.”

“Science doesn’t exist.” The Slytherin teased, smiling when Senku sighed.

Sorry, I forgot it was only part of my wild imagination.”

Chapter Text

“Did you find anything interesting yesterday?” Ukyo asked, looking at his friend, who was staring out the window. They were both sitting on the windowsill of a random hallway, relaxing during their free period.

“No. I was wondering…” Gen’s voice trailed off. He rested his forehead against the window glass, feeling the sun warm his skin.

“You’re thinking what?”

He sighed, looking back at his friend.

“Should I ask Senku for help?”

Ukyo had to try his best not to smile when he heard that, shrugging and looking out the window instead. “Shouldn’t you think about asking a professor for help first? Maybe they’ll be more helpful.”

The Slytherin sighed again and hugged his legs, resting his cheek on his knees. His gaze drifted to a group of students that were playing football in the courtyard.

“I know they won’t help me.”

“And what makes you think Senku will?”

Gen looked back at his friend, frowning. “…I forgot to tell you.”

“What?”

“You were right. Senku did come to the infirmary.”

Ukyo leaned back with a triumphant smile, folding his arms. “I told you he was too embarrassed to come with us.” His friend blushed and rested his head on his knees again, hugging his legs tighter. “So, how was it?”

“How was what?”

“His visit to the infirmary.”

“…He’s staying here for Christmas, so I guess I won’t be alone for once.” Gen mumbled.

Ukyo sighed, leaning towards his friend. “You know you can come over to my house for Christmas anytime, right?”

The Slytherin nodded, turning around and lying on the windowsill, resting his head on Ukyo’s stomach. The blond instantly wrapped his arms around him.

Gen sighed. “I know Christmas is an important time of the year for you and you like to spend it with your family.”

“And what? You’re also my family.” Ukyo shrugged.

He pressed his face against the blond’s stomach, whining. “I told you not to say those things.”

The Hufflepuff smiled, rubbing Gen’s back. “But it’s the truth.”

They stayed silent for a few minutes, Ukyo looking out the window while his hands travelled up and down Gen’s back, who was still lying down with his head on his stomach.

“I think I’ll ask Senku for help.”

 

———

 

“I asked Ukyo yesterday.” Chrome casually said while adding some powdered moonstone to the potion he was trying to brew.

“What?” Senku asked confused, opening another cabinet in hopes he’d find what he was looking for.

“Whether Gen and Ryusui are actually dating. He said they aren’t.”

Senku side-eyed his friend. He was almost going to say he already knew, but stopped himself.

“Oh. Okay.”

“I also asked him if Gen’s gay, but he chuckled and said ‘Why don’t you ask him yourself?’” Chrome mimicked Ukyo’s voice almost perfectly. “Idiot.”

Senku frowned. “Why would you want to know that?” He closed the cabinet door with a sigh, turning around to check his book for the ingredients he was missing.

“Because everyone talks about how he’s been with both girls and boys and I don’t know what to believe anymore.”

Senku’s frowned deepened. “You know he can be bisexual, don’t you?” His voice sounded harsher than what he intended to.

His friend looked at him with his eyes wide open, slightly blushing. Before he could respond, though, the Potions classroom door opened.

Ukyo and Gen walked inside, and the blond Hufflepuff smiled when he saw Chrome.

“Hey, what are you doing?” He asked, leaning over Chrome’s table and looking into his cauldron.

Draught of peace.”

Senku sighed and turned around, ready to open another cabinet to look for more ingredients, bumping into Gen instead, who was observing all the ingredients laid out on his desk.

“You’re missing ingredients.” The Slytherin muttered.

The blond pursed his lips and grabbed Gen by his shoulders, carefully pushing him out of the way.

“I know.” He mumbled, opening another cabinet to look for them.

Gen leaned against the cabinet, looking at him. “Can we talk later?”

The Ravenclaw looked down at him and frowned. “What?” He asked, dumbfounded.

“I need to talk to you. Can you come to my flying class later?”

Senku stared at Gen for a few seconds, still processing what he’d said, until he shook his head, looking back into the cabinet and trying for his face not to blush even more.

“…Yes, I’ll be there.”

 

———

Senku stopped in his tracks when he saw Gen. He was sitting down on the grass, Kohaku’s head resting on his lap, while Ukyo and Ryusui fought, rolling on the grass and laughing.

He could turn around and leave them alone; enjoy their free time together.

But the interest he had in what Gen wanted to tell him was bigger.

Senku took a deep breath before walking towards them.“Gen?”

Kohaku sat up and Gen turned around, smiling when he saw him.

He stood up instantly. “You came.” He said when the Ravenclaw walked closer to him. Gen turned back to Kohaku. “We’ll be back in a second.”

“Another day without even trying to fly…” She sighed, lying back down on the grass.

Senku followed Gen towards the entrance to the Forbidden Forest, where their Care of Magical Creatures class took place. HE sat down on one of the rocks that were used as a bench and gestured at the Ravenclaw to sit next to him.

The blond sat, still confused, looking away from Gen. He concentrated on the way the sunlight filtered through the trees instead.

“I need your help with something.” Gen spoke, fiddling with a strand of grass.

Senku finally turned to him. “My help? With what?”

He couldn’t help but feel his face heat up when he noticed the way the leaves projected shadows on Gen’s face, making him look even prettier than what he normally did.

“…I think I’m being haunted by a ghost.” His voice was soft, close to a whisper.

The blond needed a second to process what he’d said. “What do you mean?”

“She appears every time I’m alone at night and tries to approach me. Apparently, I’m the only one who can see her.” Gen kept avoiding Senku’s gaze, still nervously playing with the strand of glass.

The blond swung a leg over the bench, directly looking at him. “The day you were found on the hallway—”

“Yes. I fainted when she got closed to me.” Gen finished for him.

Senku looked down when he heard that, taking a deep breath. “I don’t know how I’d be able to help you, though. I don’t know a thing about ghosts, and—”

The Slytherin finally looked at him, talking before he could finish. “Please,” He stretched his hand towards Senku’s, but stopped midway, hesitating. “You know the Hogwarts library better than I do.”

He rubbed his temples, trying to think of what he should do, finally sighing. “Okay, I’ll help you.” Senku looked up. The Ravenclaw’s eyes had lit up. “I can’t promise anything, though.”

“It’s okay. If you research with me instead of using all your free time to study science it’ll be enough.” Gen smiled, making Senku frown.

“I spend more time studying about magic now because of you.”

The Slytherin grinned. “That’s a good thing, then.” Senku ignored his words in favor of staring at a Thestral that was trying to catch a bird some meters away from them. “Let’s call a truce, then. We’ll stop competing in class and focus on the ghost for now. How does that sound?”

Senku looked back at him. Gen was smiling, a small blush spreading through his cheeks.

“…Okay.”

“Really?” The Slytherin’s smile got bigger when the blond nodded again, shoulders slumping with relief. “Thank you.”

Senku felt his face heat up when he heard how genuine those words sounded.

“I’m still going to study science, though.” He teased.

Gen sighed dramatically. “That’s a waste of time.”

“The day you see me getting in a spaceship headed to the moon you won’t think the same.”

The Slytherin chuckled and threw the strand of grass he’d been playing with at the blond. “Keep dreaming.”

Chapter Text

“Senku! Wait, wait.” Gen grabbed his last piece of toast before rushing towards the Ravenclaw, who was walking out of the Great Hall with his friends.

“What?”

The Slytherin raised his hand, asking him to give him a second, while he finished munching on his last piece of toast. Senku folded his arms, waiting.

“Library after class?” Gen asked finally.

The blond frowned before walking out of the Great Hall, followed by Gen.

“Don’t you have flying class?”

“We both know I’m not going to fly, so why bother?”

Senku stopped, making the Slytherin almost bump against him. He glared at Gen, who was still chewing his breakfast, and sighed.

“If you don’t make an effort on your flying classes, I’m not going to help you.”

“What?” Gen pouted, following Senku down the hall. He wasn’t aware of all the students that had stopped to stare at them, but the blond was, and it was getting on his nerves.

“You heard me.” He turned around, trying to get back to Chrome, Taiju and Yuzuriha, but found a bunch of students looking at them instead. He sighed and tried to find his way between the other students, still followed by Gen.

“Okay, and after flying class?”

Senku stopped to look at him again. “We can also go to the library after Astronomy.” He suggested, silently begging for Gen to say yes and end this conversation as fast as possible. He could hear students murmuring.

“Ukyo doesn’t let me stay past midnight, in case I go back to the Slytherin common room alone and the ghost appears again.”

“I’ll walk you back to Slytherin, then.” Senku said.

Gen looked up at him with a cocky smile. “What?”

“I’m not going to say it again.” The blond huffed, entering the classroom, still trailed by Gen, who was sighing dramatically.

“Fine, fine! I’ll stay with you after Astronomy class.”

Senku turned around when he heard that, smiling at him. “Okay.”

 

———

 

“I promise I’m going to make an effort today.” Gen wrapped his arms around Kohaku’s waist, hugging her tightly.

“You say that almost every day.” She sighed, pushing him away and handing him her broomstick. “Prove it.”

Gen forced a smile, grabbing the broomstick hesitantly.

“Just put it between your legs.” Kohaku said with a smile, making the Slytherin glare at her.

“I know where to put it.” He huffed when she started laughing, making a disgusted face. “Gross.”

“Be careful of what you say. People are listening.”

Gen turned around and almost dropped the broomstick when he saw Senku.

“Go away! I’m not going to fly if you’re here looking.!” He yelled.

The Ravenclaw smiled, lying down on the grass with his arms behind his head. “I’m not looking now!” He yelled back, staring up at the cloudy sky.

Gen sighed. Kohaku frowned at Senku and then at him, confused.

“Why is he here?” She asked, staring at the Slytherin while he sat on top of the broomstick.

It was obvious Gen was trying his best not to smile, instead feigning annoyance. “He has agreed to help me if I actually make an effort and learn how to fly.”

Kohaku grinned at him when she heard that, leaning towards him. “Do you like him?” She asked in a whisper.

The question took Gen by surprise, instantly feeling his face heat up. Before he could respond the broomstick took off, elevating a few meters off the grass.

His heart was going to explode. Kohaku’s words were still resonating inside his mind, and the feeling of his feet not touching the grass was bringing back memories from the last time he’d flown, all of them rushing into his mind all at once.

Gen took a few deep breaths, trying to calm down, and closed his eyes.

“Kohaku, put me down.” He ordered as calmly as he could, although his whole body was shaking.

“Make sure not to look down!” She warned, although Gen was only three or four meters up in the air.

Her words made him do the complete opposite; he opened his eyes and searched for Senku, who was grinning up at him.

Gen closed his eyes again, feeling the panic surge up again. “Kohaku, I said put me down!” He tightened his hands on the broomstick.

“Why don’t you try moving a bit?” She asked.

The Slytherin lowered his head, eyes still tightly shut. “Please.” He asked again, loud enough for Kohaku to hear it.

He felt the broomstick move slowly, until his feet were touching the grass. Gen instantly jumped away from the broomstick, sitting down on the grass and covering his face with his hands.

“Gen? Was that too much?” Kohaku sat down in front of him, resting her hand on his shoulder. He ignored her, trying to focus on something else other than the fact that he’d been up in the air a few seconds ago.

“Gen,” Senku’s voice made his whole body tense. He didn’t move, still covering his face.

“Go away.” He didn’t want to see Senku’s reaction, so he just hugged his legs and hid his face against his knees, trying his best not to cry.

The blond obeyed instantly, turning around and walking away from them without saying a word. Kohaku watched him before turning her attention back to Gen.

He stayed like that for what felt like an eternity, his body shaking and mind repeating the moment again and again, until he felt someone sit in front of him. Gen raised his head just enough to look, and right when he saw the Hufflepuff scarf he threw himself into Ukyo’s arms, pressing his face against his shoulder and lying on top of him.

“It’s okay.” His best friend whispered, rubbing Gen’s back.

Kohaku looked at the two boys and exhaled deeply, finally feeling some guilt lift off her shoulders. “Who told you to come?”

Ukyo wrapped his arms around Gen, hugging him tighter, before mouthing at Kohaku, not wanting the Slytherin to hear it.

“Senku.”

 

———

 

Gen gripped the book tighter against his chest and walked over to Senku, who was sitting down on one of the sofas, eyes fixed on a book.

“Hey,” The blond looked up, gazes meeting. It took Gen a second to talk again. “I’m sorry for before.”

“Are you feeling better now?” Senku asked, standing up and putting his things away inside his backpack.

Gen blinked, confused. “What?”

The blond stopped and turned to him again. “Are you okay?”

He nodded, still shocked by the question. He stepped back when Senku swung his backpack over his shoulder.

“We should go have dinner, so we don’t arrive at Astronomy class late.” Senku made his way towards the library door, followed by Gen.

“I’m sorry about what happened before.” He repeated.

The blond stepped in the middle of the hallway to turn around and look at him. “You don’t need to apologise.” He shrugged before continuing his walk to the Great Hall.

“But—” Gen stopped himself when Senku walked away without waiting. He sighed, feeling even guiltier than before.

Chapter Text

It was a clear night, although the cold from the winter was already glooming over Hogwarts. Almost all the students were wearing their capes and their house scarfs, and a fireplace had appeared in the middle of the Astronomy tower.

Gen was sitting with his legs crossed near the fire, a book resting on the floor in front of him.

Senku had been staring at him, until Ryusui appeared and hugged the Slytherin from behind, pressing his chest against Gen’s body. Senku looked away.

“You don’t hug me nearly as much as they do.” Taiju pouted at the Ravenclaw.

He frowned. “Ask Yuzuriha.”

Taiju softly slapped Senku’s shoulder, making the blond wink at him, grinning.

“She’s always with Ukyo now. It’s as if they’re plotting something.” He complained. Senku shrugged, gaze travelling to the fire. “Do you know something about it, Chrome.” Taiju glanced at the brunet.

 “I don’t know a thing.” He muttered. Before Taiju could ask him anything else, Mr. Pargan appeared.

The class was surprisingly quiet. Everyone was expecting Senku and Gen to start competing against the other, but that moment never came. They both stayed silent, paying attention to what the professor was saying, and sometimes they answered some questions, but nothing else. The tension was gone.

Even Chrome could feel everyone’s disappointment when the class finished.

He turned towards Senku, who was putting his things away, completely unbothered.

“Why aren’t you both annoying each other today?” He asked, confused, but before the blond could answer him Gen walked up to them, gaze fixed on Senku.

“Let’s go.” He said with a smile. The blond Ravenclaw instantly stood up and followed him down the stairs.

Chrome turned towards Taiju confused. The other shrugged. “I have no idea.”

 They stayed silent for a few seconds, eyes widening when they realised.

“Yuzuriha.” They both said at the same time, instantly standing up and rushing to find their friend.

 

———

 

Gen was blaming it on the lack of physical contact he’d been having for the last weeks, although he knew that wasn’t it.

Still, the urge to just curl up against Senku’s body while they were both sitting down on the library floor was too much.

It felt like a weight was put on Gen’s shoulders, making him incapable of thinking or moving, and that it would disappear if he just wrapped his arms around Senku’s waist and nuzzled against his neck.

He forced himself to look away, trying to distract his mind from that need for physical contact by looking at some random book titles.

“Look, there’s some information here.” Gen turned to Senku instantly, getting closer to him to get a look at the book. “How does the ghost you saw look?”

“It’s a woman. Not old, maybe mid-thirties. Her hair is dark but it’s almost all gone, and her lips are sewn together.” Senku listened attentively while Gen describer her, his eyes skimming through the page. “She also has her intestines hanging out.”

He sighed. “Nothing interesting here. What was she wearing?”

“A white dress. It looked like a nightgown.”

Senku hummed, leaning back against the bookshelf. Gen couldn’t take his eyes off him. “She must’ve been violently killed in her sleep. That’s enough of a reason to come back from the dead. Some unfinished business she needs to deal with.”

“Why me, though?” Gen asked, also leaning against the bookshelf, hugging his legs against his chest.

“…Well, maybe Ukyo is the only one who can’t see her, you know.” The blond looked at his watch and pursed his lips. “It’s almost midnight. Want to go back?” He tried to sound as casual as possible, but Gen noticed the slight tone of worry in his voice. The Slytherin felt his face heat up.

“Don’t you want to see her?” He looked up at Senku, who had stood up.

“I think you’ve already felt too many extreme emotions for today.” The blond offered his hand to Gen to help him stand up. Gen took it with a smile. “Plus, I’m going to walk back to Ravenclaw alone, so maybe I’ll bump into her alone.

“If you do, run.” The Slytherin said with a smile, grabbing his backpack.

He walked out of the library alongside Senku, both in a comfortable silence until Gen talked again, trying to distract himself from the way his heart was wildly beating inside his chest.

“How’s your father?”

Senku shrugged. “I haven’t heard anything from him since the last letter he sent. I suppose he’s busy with training.”

They finally arrived at the Slytherin entrance, and Gen turned around to look at Senku.

“Be careful.” The blond nodded, cheeks slightly blushing. “See you tomorrow.”

“Bye.” Senku turned around and started walking down the hallway, Gen’s eyes following him until he turned right and disappeared.

Chapter Text

“How was flying class today?” Senku asked when Gen walked up to him and sat down on the sofa.

“I just sat on the broomstick, as usual.” The Slytherin sighed, turning to Senku, who was reading a book titled Ghosts & other creatures. “Have you found anything interesting?”

The blond sighed. “Nothing. Every book I’ve checked says you should just ask her what she needs.” He closed the book and left it on the table, glancing back at Gen.

“Should I?” He asked.

Senku frowned. “What?”

“Should I just stop avoiding her? She hasn’t appeared in weeks.” Gen’s eyes met Senku’s, and the blond’s heart skipped a beat when he saw how worried he looked, having to fight against his willpower to not stand up and hug him right then and there.

“…Maybe she has solved it alone.” Gen lowered his gaze, fiddling with the pen he was holding. He was pouting slightly. It was what made Senku talk again. “But if you want, we can try today.”

“Today?”

“If you want.” Senku repeated. “We can stay studying until late, see if she appears.”

“And what if she does?” Gen asked softly, scared.

The blond pursed his lips, reaching out to rest his hand on the Slytherin’s arm, but he chickened out last second. His hand fell limply on the armrest. “Well, we’ll just run until we lose her.”

That made Gen chuckle. “And sleep at the infirmary again?” He sighed, rubbing his temples.

“A sleepover would be fun.”

Gen looked up at the blond, who smiled, slightly blushing. “I’m sure you’re the boring type who only reads in sleepovers and tells everyone to stop talking.” He teased.

Senku threw a pen at him, smiling. “You don’t know what you’re missing.”

“Okay,” The Slytherin said suddenly after a few minutes in silence.

The other frowned. “What?”

“Let’s do it today.”

They both stared at each other, blushing, until the blond nodded.

“Okay, let’s do it.”

 

———

 

Gen was trying his best not to fall asleep right there. They were sitting on the floor of some random library section, each one reading some book that talked about the afterlife.

He rested his head against the bookshelf, closing his eyes. He didn’t realise Senku was staring at him.

“It’s already half past midnight. Do you want to go back?”

Gen half-opened his eyes, looking at him. “It’s okay.” He mumbled, curling up on the floor and using the blond’s backpack as a pillow.

Senku stared at the Slytherin’s sleeping face for a few seconds, hypnotized by the way his features softened with sleep.

He closed the book he’d been reading and put it back on the bookshelf. “Let’s go.” He said, resting his hand on the Slytherin’s shoulder. Gen opened his eyes when he felt his touch. Senku pulled his hand away instantly, regretting it. “Come on.” He stood up and grabbed Gen’s backpack.

The Slytherin sat up and rubbed the sleep away from his eyes. Senku offered him his hand, helping him stand up.

Gen took the blond’s backpack, swinging it over his shoulder before speaking. “Can’t we stay here?”

Senku smiled. “Scared.” The other nodded, lowering his head. “…It’s okay. I’m not going to leave you alone.”

“Is it true that you can project a Patronus?” Gen asked, raising his head and looking at the blond.

He exhaled deeply, evading his gaze. “…Yes.”

“We can try using it with the ghost!” The Slytherin took a step towards him, eyes widening.

“I don’t think so. If I can’t see her, I doubt my Patronus will do anything.”

“But trying won’t harm anyone.” Gen insisted.

Senku looked at him, raising an eyebrow. “You just want to know what it looks like.” The other’s smile gave him away, and he clicked his tongue.

They made their way out of the library, each one carrying the other’s backpack.

“What does it look like, though?” Gen insisted once again, nudging him.

“You will never know.”

They both turned left, towards Slytherin. Senku turned back to look at Gen, who had casually started walking behind him instead of next to him.

“…Everything okay?”

Gen was going to nod in response when he spotted something white at the end of the hallway, instantly covering his face. “Can you see her?”

Senku turned around and stared at the empty hallway. “No. Is she really there?”

He looked back at Gen, who uncovered his face, instantly making eye contact with the ghost, who tilted her head slightly, eyes fixed on Senku.

“Yes, and she’s looking at you.” Gen softly yanked on the blond’s sweater when she floated closer to them. “Let’s go, please.”

“So she really only appears after midnight. Is she walking closer?” Senku asked, staring at the empty hallway.

“Yes!” Gen exclaimed, yanking on his sweater a bit harder, making him step back.

“Do you need anything, miss?”

“He’s not going to respond to you, idiot. Let’s go, please.”

The blond finally turned around. “Okay, let’s go.”

Gen didn’t need much more prompting; he instantly turned and sprinted towards the infirmary.

“Wait for me!” Senku whined, running behind him and trying to catch up to him. “Is she following us?”

He turned for just a second, wanting to check—

Gen’s heart jumped, and he had to force himself not to scream.

The ghost was almost touching Senku, her hand stretched towards him.

“Yes, she is! Run faster!”

“This is as fast as I can go!”

 

———

 

Senku pressed his back against the infirmary door, panting.

“Did she follow you when you were with Ukyo too?” He asked.

The Slytherin shook his head, dropping down on one of the beds.  “I don’t think she did.” He sighed, trying to catch his breath. He could feel his heart pounding inside his chest like crazy.

“Are you okay?” Senku asked, back still pressed to the door.

Gen nodded, closing his eyes and resting a hand over his heart. “My heart is pounding like crazy.” The blond almost stepped away closer to him, but hesitated. “Come, feel it.” He sat up, gesturing for him to come closer.

Senku blinked before walking up to him, letting the Slytherin grab his hand between his own and place it over his chest, looking up at the blond.

It really was beating fast, like a small rabbit was trapped inside his chest, but Senku couldn’t really think about that. The infirmary was dark, no lights turned on whatsoever, but the moonlight entered through the high windows and made Gen’s gaze shine.

They stayed like that for what felt like an eternity, staring at each other’s eyes in silence while Gen kept Senku’s hand pressed against his chest.

“It’s slowing down now,” The blond said in almost a whisper, not even realised he’d leaned forward a bit.

Gen slowly loosened the grip on Senku’s hand, letting him go. “Yeah,” His gaze drifted down when the Ravenclaw fully stepped away. “…It really seemed like she wanted to catch you.”

“Maybe she has fallen in love with me.” Senku smiled.

The Slytherin chuckled softly, rubbing his eyes. “Yes, I’m sure it was that.” He took a deep breath, feeling his body still shake slightly. “That was so scary.”

Senku sat down next to Gen, staring at him worried. “It’s okay now. You should go sleep.”

He looked up at him for a few seconds, and finally pressed his forehead against the blond’s shoulder, huffing softly.

Senku looked away from Gen and fixed his eyes on the bed in front of him, feeling his face heat up.

They stayed like that for a few more minute, the Slytherin’s body relaxing even more by the second, while Senku’s blush deepened by the second, the feeling of Gen’s touch invading his mind.

“Yes. Let’s go to sleep.” Gen finally sighed, pulling away and lying down on the bed.

Senku hesitantly stood up and after grabbing their backpacks and leaving them on the floor next to their beds, he lied down on the bed next to the one where Gen was, his eyes wide open and fixed on the ceiling.

He didn’t sleep at all that night.

Chapter Text

“Where were you yesterday night?” Ukyo sat down next to Gen, taking a bite of his toast and ignoring the Slytherin’s glare.

“Who told you?” Gen asked, taking back his toast from Ukyo’s hands, muttering an insult under his breath. It made his best friend smile.

“Tsukasa.” The Hufflepuff’s smile only grew when he sighed, and he poked at his side, insistent. “So, where were you?”

“I saw the ghost yesterday.” Gen responded, munching on his toast.

Ukyo’s expression changed instantly, serious. “Really? Were you alone?” He relaxed a bit when Gen shook his head, and the smile came back to his face, this time teasing. “Senku?”

“…When I was with you that last time, did she follow us?”

Ukyo shook his head. “No. I looked back a few times and she wasn’t there. Why?”

Gen handed Ukyo the last half of his toast, and stood up.

“I don’t know. She seemed particularly interested in Senku.” He shrugged before grabbing his backpack and walking out of the Great Hall, followed by his friend.

“So you slept at the infirmary with Senku?” Ukyo grinned, and Gen looked down, feeling his cheeks heat up. “Oh my god, you really did.” He mumbled, stepping in front of him and grabbing his shoulders, forcing him to look up. “I’m going to ask you something, be honest.”

“What?” Gen glanced at the students that were now staring at them before turning back to his friend.

“Do you—?” Before he could finish his question he was interrupted by Ryusui, who threw himself on top of Ukyo, hugging him from behind.

“Missed me?” Ryusui asked, winking at Gen, who smiled.

Ukyo groaned, trying to push him away. “Get off me.” It only made the Gryffindor tighten his arms around him, insistent.

Kohaku appeared behind Ryusui, face serious. She grabbed him by his sweater, forcefully pulling him away from Ukyo and pushing him towards class.

“She’s fuming.” The Hufflepuff observed, staring at the two walk away.

“Why?”

“They have a match today and Ryusui’s been missing quidditch training.”

Gen raised his eyebrows. “There’s a match today?”

“Yes, Ravenclaw vs. Slytherin. Didn’t you know?”

 

———

 

“You didn’t come to breakfast.” Yuzuriha said, sitting down on the table next to Senku, who was still eating. The blond nodded, calmly chewing his food.

“He didn’t sleep at Ravenclaw yesterday, so he decided to skip breakfast and sleep a bit more.” Chrome grinned when Senku glared at him.

Taiju’s eyes widened, and he leaned forward, curious. “Where did you sleep?”

“The infirmary.” The blond tried to feign casualness, taking another bite of his food.

“But tell them who you were with.” Chrome teased, whimpering when Senku kicked his ankle under the table.

Yuzuriha gasped dramatically. “Gen?!”

The blond Ravenclaw nodded again, still eating.

“And you didn’t sleep? What did you do?”

Taiju’s question made Senku choke on his food, coughing for a few seconds before he was able to talk again. “We didn’t do anything. I was just too nervous to sleep.”

The three of them grinned, not really buying it.

“And why did you sleep together in the infirmary?” Yuzuriha rubbed Senku’s cheek with the back of her hand.

The blond backed away, scowling. “Sleepover.” He mumbled, and his friends chuckled, amused with his reactions. He stood up, ignoring them. “We have to go to class.”

Yuzuriha stood up instantly and followed him out of the Great Hall, Chrome and Taiju some steps behind them.

“Do you like him?” She asked, softly bumping their shoulders together.

“Who?” Senku asked, acting like he didn’t know who she was talking about.

“Gen.”

“I don’t.” The blond mumbled, gaze drifting down. Yuzuriha grinned at his reaction.

Before she could say something Taiju caught up to them, swinging his arm over Senku’s shoulders.

“Hey! Are you coming to watch the quidditch match today?”

“No. I’m going to the Astronomy tower.”

“Date with Gen?” Chrome teased, smirking at Senku.

The Ravenclaw rolled his eyes, feeling his face heat up. “Shut up, idiot.”

 

———

 

Senku sighed, eyes fixed on the ceiling, before sitting up on the bed. He rubbed the sleep out of his eyes, trying to wake himself up.

Ravenclaw was completely silent. Everyone was busy watching the quidditch match. The whole castle was probably empty.

Senku stood up and after putting his scarf on and taking his backpack he walked out of the Ravenclaw tower, heading towards the Astronomy one.

He walked up the stairs slowly, and sighed when he found that the fire had been put off. Taking out his wand of his pocket, he lit it back up with a simple flick of his wand. Senku sat down on the floor, close enough so his body stayed warm, and after taking a notebook and pen, he started writing down the names of all the stars he was able to see.

Senku’s gaze fell on his backpack, distracted, staring at the small pocket on its side. With a small side, he opened it and took a mobile phone out.

He turned it on, the white screen blinding his eyes.

Once it was running, he dialled a number and waited.

“Hello?” Byakuya’s voice instantly made him smile, and Senku lied down on the floor, looking at the sky.

“Dad.”

“Senku? I thought you weren’t allowed to bring mobile phones to Hogwarts.” Byakuya tried to sound angry, but the blond knew he was smiling.

“I just felt like hearing your voice, that’s all.”

“How’s everything over there?”

Senku smiled and closed his eyes. “It’s okay, I guess. Everyone is watching a quidditch match, so I’m alone at the Astronomy tower.”

“You can see the stars from there?”

The blond put the speaker mode on and left the phone next to him, looking back at the sky. “Yeah. It’s a clear night here.” He sighed.

They stayed silent for a few seconds, until Byakuya asked.

“Who are you going to stay with for Christmas?”

Senku grinned and put his hands behind his head. “Well, it’s someone I’ve met this year, but…” He heard someone walk up the stairs, and instantly jumped up. “Someone’s coming. I’ll call you later, okay?”

Before Byakuya could answer he hung up, hiding the phone inside his backpack.

His heart skipped a beat when he saw Gen.

Chapter Text

The Slytherin smiled and walked up to him.

“Weren’t you at the match?” Senku asked, confused, still staring at Gen.

“Chrome told me you were here.” Gen walked over to the battlement and leaned over it, looking over at the quidditch pitch, where the match was still going.

The Ravenclaw blinked. “And you came?”

Gen turned around, about to respond, when a Thestral flew over their heads. He smiled, looking at the beast fly away from them, and leaned his back on the battlement with a small sigh. “I’ve never seen one so close to the castle. I suppose all the noise from the quidditch match has scared him.” He looked back at Senku, who was staring at him wide-eyed. He blushed when he realised he’d said it out loud.

“So you can see them too.”

The Slytherin sighed and turned back around, leaning over the battlement again, not daring to look back at Senku. “…I do.”

Senku stood up and walked over to him, resting his elbows on the railing made of stone and looking over at him, not asking. Waiting.

He looked down at his hands, taking a deep breath before talking again. “It’s the reason why I’m afraid of flying.”

The blond looked away from him and Gen took another deep breath, suddenly feeling guilty for mentioning it.

“…You’re the first person I know that can also see them.” Senku said after a few minutes in silence, making Gen turn to look at him.

“Weren’t you scared the first time?”

Of course I was.” He chuckled. “Imagine arriving at Hogwarts and seeing them for the first time. I almost peed my pants.”

Gen smiled, gaze drifting back at the quidditch pitch. “I found out some of them lived on the forest near my house after…” His voice trailed off, and he sighed. “I started spending time with them. They’re surprisingly friendly.”

“They’re like a small present to compensate for what you’ve lost.” Senku said in a low voice.

Gen turned to him, feeling the tears well up in his eyes. “Yeah. I guess they are.” He said, a lump on his throat.

The blond looked worried. He took a step closer to him, trying to come up with the right words to comfort him. “Sorry, I didn’t mean to—”

Before he could finish Gen threw his arms around his neck, pressing their bodies together in a tight hug. Senku hesitated for a second before hugging him back carefully, wrapping his arms around his waist.

Against him, Gen body was slightly shaking, but he was still warm, a solid presence between his arms, making his stomach flutter. He almost jumped when the Slytherin pressed his face against his shoulder, tightening his arms around his neck. One of Senku’s hands splayed on his lower back, keeping him close in hopes of comforting him just a bit.

They were hugging. It was a hug. Senku didn’t know how to calm the wild beating of his heart.

They stayed like that for a long minute, tightly holding onto each other as if their lives depended on it, until Gen backed away, wiping the sleeve of his sweater over his eyes. “Sorry.”

“No need to apologise.” Senku tried to sound as calm as possible, but the only thing he could think about was just stepping forward and hugging him again, the first one not feeling enough.

Gen nodded and walked closer to the fire, sitting down on the floor. “I’m cold.”

It was automatic; Senku took off his scarf and after sitting down on the floor too he wrapped it around the Slytherin’s neck without a word.

Gen blushed and looked down, flustered. He fiddled with the end of the scarf until he looked back up at Senku, who was gazing up at the sky.

He crawled closer to the blond and stopped when his face was centimetres away from Senku’s, who was now staring at him wide-eyed. Their hands were faintly touching, resting on the floor.

The Ravenclaw still couldn’t get over how Gen’s eyes sparkled in the night. It was as if the sky was reflected in his eyes, and it just made him want to lean forward.

That’s exactly what Gen did.

Their noses were brushing, eyes fixed on the other’s lips, their breaths intertwining. Both of their faces were red, blushed with a mix of want and embarrassment, their hearts pounding hard inside their chests.

Senku leaned towards him a bit more, feeling the faintest touch of Gen’s lips, but before he could kiss him properly the Slytherin completely backed away.

“I’m sorry.” He whispered before standing up and rushing down the stairs, running away from Senku.

The blond stared at the stairs dumbfounded, the feeling of Gen’s lips brushing against his still in his mind and making his thoughts blank.

He slowly lied back down on the floor, covering his face with his hands and groaning.

Why had he let himself lose control of his feelings so easily?

Chapter Text

“Gryffindor won yesterday. I guess that’s why Kohaku isn’t angry at Ryusui anymore.” Ukyo said, looking down at the two blonds, who were playing football on the courtyard, bickering and laughing.

“Hmn.” Gen responded, his forehead pressed against the window.

Ukyo turned back at him, staring for a few seconds and then opened his arms. In less than a second Gen was hurrying to hug him, resting his whole body against the blond’s. Ukyo rubbed his friend’s back, looking at him worried.

“What happened?” He asked.

Gen pressed his face against the blond’s chest, feeling a lump on his throat. “…I almost kissed Senku yesterday.”

“That’s a good thing, isn’t it?” Ukyo asked, and Gen hugged him even tighter, wrapping his arms around the blond’s waist.

“No.” Gen groaned, hiding his face on his friend’s sweater. “I’m confused. I like him, but—”

Before he could finish Chrome walked up to them, followed by Senku.

“Hi.” His smile faded when Ukyo glared at him. “What?”

The blond huffed. “Nothing.”

Gen sat up, pulling away from Ukyo’s hug, and left some space for Chrome, who sat down next to him and looked out the window.

Senku was intently staring at Gen, trying to meet his gaze, but the Slytherin was looking everywhere but at him.

“Next week is the trip to Hogsmeade. Are you going to come?” Chrome asked, excited.

“Yes.” Ukyo answered.

Gen hugged his knees, looking out the window, still feeling Senku’s gaze on him.

“Are you going to come, Senku?” The Hufflepuff asked, looking up.

The blond looked away from Gen, slightly blushing. “Yeah, I guess.”

“We could all go together.” Ukyo suggested.

Chrome grinned, eyes wide with excitement. “Yes! It’d be so much fun.”

Ukyo turned to Gen, who was staring at Kohaku and Ryusui. They were both now lying down on the grass, talking about something when Kohaku turned and hugged him, both smiling.

“Class starts in five minutes.” Senku spoke, eyes still fixed on Gen.

Chrome and Ukyo turned back to him. The Hufflepuff stood up, yanking on Chrome’s arm to make him follow. “You’re right. We should get going now.” He dragged the brunet away from him, leaving Gen and Senku alone.

“Yesterday—” Before the blond could finish, Gen stood up.

“Just forget it.” He said before walking away from him.

 

———

 

Chrome stared at Senku, waiting for him to talk. The blond kept fiddling with a leaf he had found on the floor, evading his and Taiju’s gaze.

He had asked them to come with him to a more private place to talk about something that was worrying him, yet he had been silent for the past five minutes.

Taiju and Chrome turned to each other, confused.

The brunet Ravenclaw sighed. “So, what did you want to talk about?” He asked in the most casual way possible, making Senku look up to him.

“Well…” His voice trailed off, and he groaned, tossing the leave and covering his face with his hands. “The thing is, I never thought I’d ask you both for love life advice.”

Taiju barked a laugh and patted Senku’s back hard, almost pushing him to the ground. “I’m so happy for you, Senku! I thought you couldn’t feel anything!”

The blond coughed and grabbed the railing, trying to recover from the deadly pats.

“What do you want to know?” Chrome asked, leaning against the wall.

“How do you know if you like someone?”

Taiju and Chrome looked at each other, confused, then back at the blond.

“What?” Taiju asked, grinning.

“Like, I of course know the typical things; your heart beats faster every time they look at you, you want to be with them all the time, you can only think about them… But what if all that is just the need to know them more, not really attraction?”

Chrome frowned. “Is this about Gen?”

Senku covered his face with his hands once again, feeling his face heat up even more. “Yes.”

His two friends grinned.

“Then what’s the problem? You’re together all the time. If you like each other, it’s just a matter of time.”

Senku looked up at them, and sighed when he saw their faces, giving up on the conversation.

“I’m going to write a letter to my dad.” He muttered, walking away from them and leaving the two alone.

Chrome and Taiju looked at each other, huge smiles on their faces, and high-fived, excited.

“We have to tell Yuzuriha!”

Chapter Text

Senku sighed when his father didn’t answer his third call, putting his mobile phone back inside his backpack.

He entered the library and walked towards the spot he’d always study at, hoping he’d find Gen there.

To his surprise, there he was. Gen was sitting with his legs dangling over the armrest and his back resting on the other one, a textbook on his lap. His eyes were focused on the book.

Senku took a deep breath before walking to the sofa in front of the Slytherin’s and sitting down.

“I found something interesting today.” He spoke, his whole body relaxing when Gen turned to him, gaze looking as always. Normal, curious, blue eyes fixed on him.

“What?”

“Ghosts can haunt you if they’re interested in something you have. The other day she wanted to approach me, and I was wearing your backpack, right? Maybe you have something that used to belong to her when she was alive.”

Gen stayed silent for a few seconds, eyes fixed on Senku, deep in thought, trying to go through all the things he had on his backpack mentally.

“…I don’t think I have anything else apart from my textbooks and my pencil case.” He muttered, sitting upright on the sofa and taking his backpack. He opened it, and froze when he remembered what he did have.

Senku’s scarf.

He pulled it out slowly, feeling his face heat up, and looked up at the blond.

“I forgot to give it back to you. Sorry.”

The Ravenclaw waved his hand in dismissal when Gen stretched his arm to hand him the scarf. “It’s fine. You can keep it.” That made the Slytherin frown, confused. “I never see you wearing scarves. Do you even have one?”

Gen leaned back on the sofa, leaving the scarf on his lap, blushing.

“I do, but— I forgot it at my house.” He mumbled, and Senku shrugged.

“That settles it, then. I have three or four more, so don’t worry about it. My dad went crazy buying me clothes in my first year.” They both chuckled.

Gen continued on, pulling out all the things inside his backpack.

He’d been right; there was nothing out of the ordinary, just textbooks and his pencil case.

“I don’t have anything else.” Gen shrugged, looking back up at Senku, who pursed his lips confused.

“Well, maybe it wasn’t because of that.” He sighed, leaning back on the sofa, frustrated.

Gen turned his head towards the clock on the wall. It was almost eleven. “We can try today.” He turned back to Senku, who was frowning. “Wait until midnight, leave the backpack in the hallway and wait for her reaction.”

“And spend another night in the infirmary?” Senku asked, his heartbeat suddenly picking up the pace.

Gen smiled sheepishly and shrugged.

“Another sleepover sounds fun.”       

 

———

 

Gen peeked out to look into the empty hallway and hid behind the wall again, breath shaky. Senku couldn’t help but smile, the only thought in his mind being how cute Gen looked wearing his scarf.

“Is she there?” Senku asked, and Gen rested his head against the wall for a few seconds before taking a deep breath and peeking out again.

“Not yet.” He sighed, then looked back at the blond, who grinned. “What are you laughing at?” He softly slapped Senku’s arm, who backed away giggling.

“Nothing, nothing.”

Gen glared at him before looking back at the empty hallway and—

He gasped.

“She’s finally here.”

The Slytherin stepped out into the hallway, followed by Senku, who was holding onto Gen’s backpack. The blond threw it as far as he could, making it land with a loud thud near the ghost.

Gen stared at her. She took a step towards the backpack, examining it for a few seconds. Then, she looked back up and started rushing towards Senku.

“Oh no, oh no!” He yelled, grabbing Senku’s wrist and tugging him towards the infirmary. “It didn’t work, run!”

He didn’t dare to look back to see if she was following them, and when they finally entered the infirmary they closed it as fast as possible.

Leaning against the door, panting, Gen pressed his forehead against the door and whimpered. “My backpack.”

Senku chuckled, still trying to catch his breath.

The Slytherin walked over to the bed where he had slept the last time and dropped face down on it. “I think she likes you.” He said, voice muffled by the pillow.

“I think so too.” Senku huffed a small laugh, walking over to the bed next to Gen’s and sitting down on it.

“She isn’t the only one who does.” He whispered almost inaudibly, pressing his face harder against the pillow. He closed his eyes and took deep breaths, still feeling his heartbeat fast from the sprint.

“You should get under the sheets, or you’ll get cold.” Gen sighed when he heard Senku’s reproach, but took off his shoes and obeyed him, covering his body with the sheets before turning to him.

“I’m not used to sleeping this early.” He said, taking off Senku’s scarf and leaving it next to him.

“I’m not used to sleeping at all.” Senku admitted with a sigh, lying down and staring at the ceiling.

“Nightmares?” Gen asked, staring at the blond’s side profile.

He suddenly felt the urge to stand up and lie down next to him on the bed, stare at his face from much closer, even trace the shape of his nose and lips with his index finger.

Gen hugged Senku’s scarf tightly against his chest instead, hoping it’d do the trick for now.

“Not really. Just constantly wondering why I’m here.” He sighed, still looking up. His voice sounded sad. “I’m not cut out to be a wizard after all.”

“That’s a lie.” The Slytherin sat up, frowning. “You’re one of the most powerful and intelligent wizards I’ve ever met, and you’re still only sixteen.”

Senku closed his eyes for a brief moment, breathing deeply, before turning around on the bed, giving his back to Gen. “I’m not in the mood to talk about it.”

Gen pursed his lips, feeling guilty for having said that. “Sorry.”

“You have to stop apologising to me every minute.” The Slytherin bit his smile, slightly blushing. “Goodnight, Gen.”

“Goodnight, Senku.”

Chapter Text

“Any news from your mom?” Ukyo asked.

Gen kicked a little stone that was on his way, making it bounce away from them.

“Nothing. I’m not even surprised, though. She called me once in summer, so no calls during the school year is quite on-brand for her.”

Ukyo sighed and wrapped his arm around Gen’s shoulders, pulling him close.

“Are you still going to stay here for Christmas with Senku?” The Hufflepuff asked. Gen nodded, looking down at his hands. “What are you both going to do not to get bored? Study?”

The Slytherin looked up at his friend and smiled mischievously. “I have a few things in mind.”

Ukyo’s eyes widened with curiosity and surprise, but before he could ask Gen hurried away from him and jumped on top of Ryusui, who instantly grabbed him and carried him on piggyback, laughing.

“Why are they always so touchy-touchy?” Chrome pouted, turning to Senku, who frowned. “Why aren’t we like that?”

“You want me to give you a piggyback ride?” Senku asked.

He noticed the way Chrome’s gaze lit up with excitement. “Yes.”

“Ask Taiju.”

The brunette’s shoulders sagged in disappointment. He stopped, turning back to Taiju and Yuzuriha, who were walking a few meters behind them, happily conversing.

“Taiju! Can you give me a piggyback ride until we arrive at Hogsmeade?”

The Hufflepuff grinned and instantly ran towards Chrome.

“Of course!” He effortlessly picked Chrome up and started happily bouncing down the trail.

Senku sighed, hiding his smile, and waited for Yuzuriha, who was staring at her two friends.

“At that pace they’ll easily arrive half an hour earlier than us.” They both chuckled, and Yuzuriha wrapped her arms around Senku’s, resting her head on his shoulder. “I’ve seen Gen’s scarf.”

“What about it?” Senku tried his best to keep his voice neutral.

“I know it’s yours.”

 The blond sighed, but didn’t respond. Yuzuriha looked over at Gen, who was laughing at something Ryusui had said, resting her head on the other’s shoulder, arms tightly wrapped around his neck not to fall.

“Do you like him?” She asked, not really expecting an answer.

Senku took a deep breath and let out the words that had been clouding his mind for well over a week. “I think I do.”

 

———

 

Gen’s happiness that day peaked when he walked out of Zonko’s Joke Shop, his backpack full of prank objects he’d bought —in preparation for Christmas with Senku—, and found that it had started snowing harder.

The streets were covered in a small layer of snow now, and he instantly turned around to look at Ukyo, who was looking up with a huge smile on his face.

“Finally!” He said, walking to the middle of the street and stretching his hands out, feeling the snowflakes cool his hands and face.

“Is it snowing?!” Taiju yelled, running out of the shop excited, followed by Chrome and Yuzuriha.

“I hope it stays like that for tomorrow. I love playing quidditch in the snow.” Kohaku said with a smile, hurrying down to touch the snow, followed by Ryusui.

“It was about time.” He heard Senku’s voice behind him, and he turned around to smile at him. The blond was going to say something else when a snowball hit his head.

“Got him!” Taiju exclaimed, and they all started to laugh.

Senku crouched down and after making a snowball he threw it at Taiju, who swiftly dodged it.

Gen chuckled, and suddenly felt a snowball hit his back. He turned and dramatically gasped when Ukyo waved at him, smiling innocently.

“You!” He rapidly made a snowball and threw it at his friend, who dodged it and started making another one.

The snowball fight soon turned to chaos. Everyone went against everyone else. Yuzuriha hid behind Taiju, laughing, while the brunette tried to hit Ukyo at least once, but the blond Hufflepuff was too good at dodging them.

Gen was trying his best to hit Ryusui on the face with a snowball when he felt something hit his back. He turned around and noticed Senku grinning at him, three or four meters away.

The Slytherin knew he wouldn’t be able to hit him even if he tried, so he opted to run towards him instead. Senku instantly reacted and hurried away from him.

“Don’t run away, you coward!” Gen yelled, sprinting towards him. He finally managed to tackle him, both of them falling to the ground, the Slytherin lying on top of Senku.

They both stared at each other, panting, and after grabbing a bunch of snow on his hand, Gen pressed it against Senku’s cheek.

“Ouch! That’s too cold.” The blond grabbed Gen’s wrist, trying to get his hand away from his face. It made the Slytherin lean down towards him.

Their proximity made them freeze, looking into the other’s eyes, blushing. Their noses were touching, hot breaths mingling, and maybe Gen leaned forward a bit more, seeking the warmth, noticing the Ravenclaw’s arms hesitantly wrap around his waist.

Senku, whose eyes were wide open, fixed on the other’s, opened his mouth to say something when Gen noticed a snowball flying towards them. He pressed his face against the blond’s neck, and felt his hair get damp when the snowball hit his head.

He looked up again and got off from top of Senku, ready to join the snowball fight once again.

Ukyo groaned, staring at Senku’s lying figure for a few seconds before the blond Ravenclaw stood back up. “You’re an idiot.” He muttered to Chrome, who turned to look at him confused, a brand-new snowball already on his hand.

“Me? Why?! They were the perfect target!”

 

———

 

Senku looked up at the sky, staring at the way the moon shined through the clouds. He closed his eyes when he felt a snowflake fall on his cheek.

Gen was staring at him attentively, eyes following the snowflake that slowly melted and ran down the blond’s cheek.

“Are you going to the match tomorrow?” He asked, pulling himself out of his stupor.

“Yes. Taiju is playing.”

They both stopped at the castle entrance, not wanting to part ways so soon. Senku turned to look at Gen and readjusted the Slytherin’s scarf, wrapping it around his neck better. Gen’s eyes widened a bit, and he took a small step towards the blond.

“I hope it snows in Christmas too.” He muttered, looking up at the blond. Senku nodded, looking back up at the sky. “Let’s go inside.” He grabbed the Ravenclaw’s arm and dragged him inside, a small, relief sigh escaping his lips when the warmth enveloped them again.

“Do you want me to walk you to Slytherin?” Senku asked, turning to him.

Gen shook his head. “It’s okay. It’s not even late yet.”

The blond nodded and Gen smiled, feeling his cheeks blush. He stepped towards Senku and wrapped his arms around the blond’s neck, hugging him tightly. After a second of hesitation Senku hugged him back, arms carefully wrapping around his waist, not too tight.

It didn’t last long, even though they both wanted to stay together longer.

“I have to go now.” Gen backed away from Senku, who nodded, face completely blushed.

“Goodnight.” The blond muttered, watching him turn around and walk away from him, towards Slytherin.

“Goodnight!” Gen looked over his shoulder and smiled at him, before hurrying down the hallway and turning, disappearing from Senku’s view.

He couldn’t deny that his heart skipped a beat.

Chapter Text

Dad,

Do you remember that letter I sent you where I said being understood was like receiving a non-physical hug?

So, I received a real hug from that person today. And it was much, much better than all that “being understood” thing.

I’ve tried reaching out to you, but I suppose you’re busy with training.

I’m sending you your Christmas present next week, so I hope it arrives on time. If it doesn’t, I blame it on the owl.

Love,

Senku.

Chapter Text

Gen was going to follow Ukyo into the classroom when he felt someone pat his back. He turned around and smiled when he saw Kaseki.

“Good morning, Kaseki! Only eight days left until Christmas break starts.”

“Yes, about that—” The headmaster interrupted himself when he noticed the scarf Gen was wearing, and he squinted. “Weren’t you a Slytherin?”

“Yes, I am.” Gen chuckled. “This is from a friend.”

Kaseki frowned, still confused, but nodded. “I wanted to ask you if you’re going to be the only one here for Christmas this year too.”

“No, I’m staying with Senku.” Gen said with a smile.

Kaseki frowned. “Who?”

“Someone from my class. Do you want me to call him for you?” He asked, turning around and peering into the classroom, where Senku was sitting, waiting for the class to start.

“No, no, it’s okay.” Kaseki shook his head, and rested his hands on Gen’s shoulders, making him meet his gaze. “Your mom wrote to the Ministry yesterday.”

“Did she?” He asked, his voice sounding a bit bitter.

Kaseki pursed his lips. “She hasn’t contacted you since her tour started, has she?” Gen shook his head, and he sighed.

“And why did she write?” He asked, shifting on his feet, uncomfortable.

“Something about a creature on her bus tour, asking for someone to come and take care of it.”

Gen nodded. “I have to go to class now.” He said. Kaseki nodded, waved him off, his gaze filled with worry.

The Slytherin walked into class and sat down on his chair, next to Ukyo.

“What did he tell you?” Ryusui asked, leaning over his desk to stare at Gen, who shook his head and opened his textbook.

Ukyo softly pushed Ryusui to sit back on his chair, glaring at him. “Not the time to ask.” He whispered.

Gen was going to say something when he felt someone rest a hand on his shoulder. He looked up, face heating up when he met Senku’s gaze.

“Everything okay?”

“Yes, yes. Go back to your seat.” He said, flustered, feeling all of their friends’ gazes on them. He softly pushed Senku away.

“Are you sure?”

“Yes!”

Senku grinned, amused with Gen’s reaction. He obeyed, going back to his seat.

The Slytherin felt Ukyo lightly elbow him, making him blush even more. He looked back down to his textbook.

“That was cute.” His best friend said, trying not to laugh.

“Shut up, Ukyo.”

 

———

 

“If I was Taiju, I’d also be scared of playing against Kohaku and Ryusui.” Yuzuriha sighed, looking at the three players train on the quidditch pitch.

Senku nodded and folded his arms, leaning back on the bench. “They’re not even training on their regular positions and they’re still doing an amazing job.” He pointed out.

His gaze drifted back to Gen, whose eyes were following Kohaku attentively. The blond girl landed on the grass softly, while Ryusui and Taiju fought to catch a snitch.

Gen stood up and ran up to her.

“You know what some students asked me today?” Yuzuriha turned to Senku, whose gaze was still fixed on the Slytherin.

“What?”

She smiled. “Whether Gen has a Ravenclaw girlfriend.”

The blond turned to her frowning, then sighed and turned back to look at Kohaku and Gen. She looked like she was encouraging him to do something. “What did you say?”

“The truth, obviously.” The blond jumped a bit on the bench, turning to her, alarmed. Yuzuriha chuckled. “No, idiot. I just told them I really don’t know anything about his love life, and that maybe the scarf was a friend’s.”

“Did they believe you?”

“Of course not.” She snorted. “You know you’ve chosen the most desired boy in Hogwarts, don’t you? Everyone wants one of the most intelligent pure-blood Slytherins to be their boyfriend, so they see competition basically everywhere. Whoever gave their scarf to him, it’s their enemy now.” She smiled, but it didn’t seem nice. Senku was just mildly scared. “And that’s you.”

Senku frowned. “Pure-blood?”

“Yes. His mother is pretty famous in the wizarding world, didn’t you know?”

Before Senku could ask who she was, he saw Gen get on Kohaku’s broomstick, behind her. He grabbed her waist tightly and pressed his face against her back.

“Oh no. He’s gone crazy.” Senku muttered, both of them staring at how the Gryffindor girl slowly raised in the air.

“Look at you, sounding like a worried boyfriend.” Yuzuriha teased, and Senku slapped her arm lightly without tearing his gaze away from Kohaku and Gen.

“Really. I wonder what he was thinking to agree to fly with Kohaku.”

 

———

 

Gen was asking himself how he’d agreed to this, but the moment he felt his feet not touching the ground anymore he knew it was too late.

“Please don’t go too high.” He pleaded to Kohaku, still pressing his face against her back and closing his eyes.

“Don’t worry, we’re just 2 meters above the ground. I won’t go higher.” She reassured him. Her gaze drifted down to Senku, who was staring at them with his eyes wide open. “Can I move?” She asked, and Gen nodded, his arms around her waist tightening a bit.

He felt the wind blow harder against him, and knew they were flying. Gen adjusted his scarf so it covered him up to his nose, and his body relaxed a bit, although he kept his eyes closed.

“Everything okay?” Kohaku checked on him, and Gen nodded again. “We’re just going around the pitch, so you don’t have anything to worry about.”

“Okay,” He sighed, opening one eye and immediately closing when he saw his feet dangling in the air.

“Do you want to go down?” Kohaku asked when she finished going around the pitch.

“Yes, please.” Gen murmured against her back, and he instantly felt them softly land on the ground. He got off from the broomstick instantly, but before he could say anything, someone grabbed him by his shoulders and turned him around.

“Are you okay?” Senku asked worried.

Gen nodded, a huge smile on his face. “I’m fine. It was kind of fun.” He softly grabbed one of the blond’s wrists, trying to reassure him.

“But you’ve cried.” Senku frowned, confused.

The Slytherin’s hands came up to his cheeks, and realised he was right. “I didn’t know.” He mumbled, and turned around to look at Kohaku, who also looked really worried. “It’s fine, really. It actually didn’t scare me that much.” He looked at Senku, and wiped his tears off. “Don’t look at me like that, I’m fine.”

“Are you sure?” The blond asked, and Gen nodded. He took a step towards him and wrapped his arms around the Ravenclaw’s waist, hugging him tightly.

Senku froze. He looked over at Kohaku, who winked at him. Ryusui and Taiju had stopped playing to stare at them, and the blond Gryffindor gave him a thumbs up. He felt his face heat up.

After what felt like an eternity Gen backed away from him, smiling shyly.

“Should we go back to the bench?” He asked, and Senku nodded. He followed the Slytherin back to where they had been sitting before, and sat down next to Yuzuriha, who chuckled and pinched his cheek.

“You two are cute.”

“Shut up.” Senku whispered, not wanting Gen to overhear it.

 

———

 

“You did a great job, Taiju. Don’t worry about it.” Yuzuriha patted his friend’s back, while the brunet cried.

Senku crouched in front of him and wiped his tears away. “It’s your first time playing against them, it’s okay that you lost. They’re almost professionals at this.” The blond comforted his friend.

Taiju nodded, although he was still sobbing. Yuzuriha hugged the brunet.

They didn’t realise someone had walked up to them until Ukyo patted Taiju’s shoulder. “Since Kohaku started playing, winning against Gryffindor has become super difficult. It’s okay if you didn’t manage to do it today.” Ukyo spoke softly. The brunet nodded, not crying as hard anymore.

“We should go back to the castle. It’s starting to get colder.” Senku said, and the other three nodded.

They started walking towards the castle in silence, Yuzuriha murmuring Taiju words of encouragement.

“So you’re staying with Gen here for Christmas.” Ukyo turned to Senku, who looked away from him and nodded. The Hufflepuff stepped a bit closer to him, voice lowering, as if he didn’t want anyone else to hear him. “Please be with him at all times, in case the ghost appears.”

“I’ll try.”

Ukyo grinned. “And shower him with as much love as you can.” Senku frowned, and the other sighed softly. “He gets pretty sad during Christmas, so some hugs and cuddles will make him feel better.

“I— Um. I’ll take it into account.” Senku looked down, feeling his face heat up just at the thought of it.

Ukyo chuckled softly and patted him on the back. “Thank you.”

Chapter Text

“Finally,” Chrome sighed, jumping out of class with a big smile on his face. “Christmas!” He turned around to look at Senku. “What are you going to do? Study?”

“I think I’m going to keep working on a robot I tried building in summer. Why?”

“A robot?” The brunet scrunched his nose. “Why don’t you just build a puppet and use magic to make it move?”

That made Senku sigh, waving his hand in dismissal.

“Can you teach me how to build one?” Gen chimed in, grabbing Senku’s arm and yanking on his sweater softly, trying to get his attention.

“Do you even know what a robot is?” The blond frowned.

Gen grinned, softly blushing. “Maybe? I’m not sure.”

The Ravenclaw sighed and looked away from him.

“Do you even have enough materials to build it here?” Yuzuriha asked, and Senku nodded.

“I brought here everything that I needed, so I shouldn’t have any problems.”

She nodded, smiling at him warmly. “If you need anything I can send it to you.” Her gaze drifted to something behind Senku.

He noticed, turning around to find a group of people around Gen, wishing him a happy holiday.

“Taiju and I have to go back to Hufflepuff to pack our clothes. We’ll meet you later at the castle entrance, okay?”

Senku turned back to Yuzuriha and nodded. “I’ll be in the library in the meantime.”

 

———

 

Chrome felt someone grip his arm. He was dragged to one side of the hallway. Looking up, his eyes met Ukyo’s, and he instantly felt his face heat up.

“What do you want?” He asked in almost a whisper, looking over at his friends, who were now walking away, to make sure they hadn’t realised he was missing.

Ukyo pouted. “Aren’t you going to give me a goodbye kiss?”

The brunet felt himself blush even more. Ukyo’s soft, pale hair was brushing against his forehead, tingling. “Don’t say those things here.” He whispered, alarmed.

The Hufflepuff smiled, pinching one of his cheeks. “But you look so cute all flustered.”

Chrome slapped his hand away, but before Ukyo could step away he grabbed the sleeve of his sweater, standing on his tiptoes and pressing a soft kiss to the Hufflepuff’s cheek.

He instantly backed away and ran down the hallway, leaving Ukyo alone.

The blond grinned and pressed his forehead against the wall, feeling his face heat up.

 

———

 

“I’m so sad we won’t get to see Byakuya this Christmas.” Yuzuriha said, hugging Senku tightly.

The blond rubbed her back, closing his eyes and sighing. “I know.”

Yuzuriha pressed her head against Senku’s chest, and Taiju wrapped his arms around them both, crushing them in a tight hug. “It’s going to be our first Christmas holidays without you, Senku.” He said, holding back his tears.

The blond frowned, softly pushing them away. “Okay. You’re going to see me in two weeks, so don’t get so emotional now.” Both of them backed away, and Chrome rushed to hug him.

“I hope you don’t burn Hogwarts down with your science experiments.”

Senku chuckled, and hugged him back. “Don’t worry about it.”

The blond looked over at Gen, who was hugging goodbye to Ukyo, Kohaku and Ryusui, and softly blushed.

So it was real.

They were going to spend two weeks alone at Hogwarts, with no one else to disturb their peace.

“Senku! You better take care of him.” Ryusui called, wrapping his arm around Gen’s shoulders and rubbing the Slytherin’s head. Gen chuckled, blushing, and tried to push his friend away.

“We should get going now.” Yuzuriha said, hugging Senku one last time before taking her suitcase. “Write if something happens!”

He nodded, pressed a quick kiss to her temple that made her smile.

“Have fun.” Ukyo said to Gen, hugging him one last time and leaving a kiss on the crown of his head.

“Yes, don’t worry.”

“And be careful with the ghost.” Ukyo repeated for the fifth time.

The Slytherin sighed. “Yes, mom.”

Ukyo waved goodbye to Senku, who was staring at them, before taking his backpack and running to catch up with Chrome and the rest.

Senku was staring at Gen when Ukyo’s words from yesterday came back into his mind.

Shower him with love.

He took a deep breath, awkwardly getting closer to him, and before Gen could say anything he wrapped his arms around his body, pressing the Slytherin against him.

Gen looked up at him, confused, and smiled when he saw Senku evading his gaze, his whole face red.

“What was that?” Gen asked when Senku backed away, and the blond shrugged.

“I just felt like hugging you, that’s it.” The Ravenclaw mumbled, looking at the ground.

Gen felt himself blush. He covered his face with his hands, and Senku smiled.

“Let’s go back inside.”

 

———

 

“Aren’t you afraid to be sleeping alone in Slytherin?” Senku asked, taking a bite of his food and looking at Gen.

“I don’t think I’ll sleep much today, so no.” Gen sighed, playing with his food. He hadn’t eaten much, but still pushed his plate away, as if he was already full.

Senku pursed his lips and looked back down at his plate, suddenly feeling overwhelmed by the silence that engulfed them.

“We could also sleep over at the infirmary.” Gen suggested.

Senku almost choked on his food. “What?”

“We could bring our bed covers and a heater not to get cold, and spend the nights there.”

The blond took a sip of his water, feeling Gen’s gaze on him. “…Yes, I guess it’s a good idea.”

The Slytherin stood up with a smile. “But not today.”

“Why?” Senku asked, standing up and following him out of the Great Hall.

Gen turned around and smiled at him almost devilishly. “I have to show you something.”

Senku frowned, but followed him. Gen stopped in the middle of a random hallway.

“What?” The Ravenclaw asked confused.

Gen turned to look at him, trying not to smile. “I bought something the other day in Hogsmeade. Do you want to see it?”

Senku wasn’t really understanding why Gen was behaving so weird, but still nodded.

The Slytherin took something out of his pocket and Senku leaned closer.

Gen jumped back. “No, you have to see it from afar. Take some steps back.”

“You’re weird.” Senku muttered, although he obeyed, walking back a meter away from Gen.

The Slytherin smiled before bringing the object close to his mouth and whispering. “One meter, two seconds.”

The last thing Senku saw was a white ray that blinded him. Then everything turned black.

 

———

 

Gen chuckled under his breath when he saw Senku petrified, and walked up to him. He had his eyes wide open and a hand stretched towards him.

He ran his index finger over the blond’s nose, stopping right on top of his lips. “You’ll be like this for a few hours.” He whispered. 2i wonder if you’ll work as a scarecrow against the ghost.”

The Slytherin looked over his shoulder for a second, suddenly paranoid, before turning back to him with a smile.

“Anyways, have fun.”

He walked around him and hurried away, going back to Slytherin. After getting his bed covers, his pillow and everything he needed for the night he walked back to the infirmary.

He pushed two beds together and left all of his things on top of them. Opening his backpack, he took a pen and some paper.

Gen walked over to the windowsill and sat down on it, looking at the night sky.

And then he began to write a letter.

Chapter Text

Hey.

My Christmas break has started today, so I’ve decided to sleep in the infirmary while my friend (more of a crush than a friend, but anyways) is petrified in the hallway.

I thought it’d be funny to petrify him and leave him there for a few hours, but now that I’m thinking about it, I kind of feel bad.

I hate Christmas, and I didn’t want him to see me like this today. But, at least, I’m not spending these ones alone.

Mom still hasn’t written. I’m not surprised, being busy with her tour and everything, but I sometimes think she just feels like she doesn’t have any children anymore.

Anyways, I’m going to try and sleep a bit, although I doubt I’ll be able to.

Happy Christmas. Miss you.

Gen.

Chapter Text

Senku had been staring at a plain wall for half an hour now, waiting for his body to de-petrify.

He blinked a few times, trying to calm his rage down, and noticed the sun filtering through the windows.

So it was already morning.

The blond closed his eyes again and felt another piece of stone fall from his face. He internally sighed.

Concentrating a bit more, he started muttering under his breath a spell to try and break it. He wasn’t really acquainted with wandless magic, but trying wouldn’t hurt.

He started hearing the stone crack bit by bit, and after a few minutes muttering he finally managed to free himself.

Senku fell to the floor with a loud thud, panting, and stood up instantly when he realised he was completely naked.

He covered himself, face completely red from embarrassment, and started running towards Ravenclaw, praying not to bump into Gen.

After he finally managed to enter the Ravenclaw tower and rushed to his bedroom. He dressed up hurriedly and dropped down on the bed, exhaling a deep sigh.

His eyebrows furrowed when he remembered Gen’s smile before petrifying him and instantly stood up.

“Time for payback.”

 

———

 

Senku rushed out of the Ravenclaw tower and ran to the infirmary.

He opened the door and found Gen inside, sitting on top of the two beds he’d put together last night.

Gen smiled when he saw Senku’s expression, eyebrows furrowed and lips pulled into a tight line.

“There you are.” He said, feigning innocence.

The blond walked up to him and rested his arms on the bed, caging him. Their faces were inches apart, but Senku was too bothered to care. “What was that for?”

“You should’ve seen our expression. It was hilarious.” Gen tilted his head slightly, studying his gaze. “Did you have fun?”

Senku gritted his teeth, and he was about to say something when he noticed the Slytherin’s eyes were puffy. His gaze drifted behind him, finding some scrunched tissues.

He leaned back slowly, eyebrows furrowing now with concern. “Are you okay?”

Gen sighed. “I thought you were going to get even angrier.” He dropped down on the bed.

“You haven’t answered my question.”

He looked up just enough to meet his gaze, quirking an eyebrow. “Why do you ask if you already know the answer?”

Senku sighed, but before he could ask something else Gen spoke again.

“You should get your things and come here. It’s snowing outside, so we don’t have much to do.”

“Did the ghost appear?” Senku asked, sitting on the bed next to Gen. The Slytherin turned towards him, and for a second he had to resist the urge to brush his bangs back.

Gen smiled, looking up at him. “No. I guess you’re a pretty good scarecrow.”

The blond nodded, fiddling with his hands. “What do you want to do today?”

Hugging his pillow, Gen closed his eyes. “I don’t want to get out bed so I’ll just lie in here for the whole day.”

Senku nodded before standing up. “I’m going to get my things.” The Slytherin nodded and hugged his pillow even tighter. “I hope you don’t petrify me once I get back here.”

That made Gen grin, opening his eyes. “You should be careful.”

The blond huffed a small laugh and stretched his arm towards him, the back of his hand softly caressing Gen’s cheek.

“I’ll be right back, okay?” He said, tone soft. Gen nodded, feeling his face blush. “Do you want anything for breakfast?”

His eyes lit up. “Croissant with marmalade.”

 

———

 

Gen took a bite of his croissant, gleaming, while Senku organised all his things.

He took his duvet, thick and with a white and blue pattern, and dumped it on Gen’s bed, making the other frown.

“What? You said you didn’t want to get out of bed today, so I’m staying with you.” The blond shrugged, taking his mobile phone from his backpack before sitting down on the bed next to Gen, who was staring at him wide-eyed.

“But I want to sleep.” Gen lied, and the blond shrugged again.

“Then sleep. I’m going to read something on my phone.”

The Slytherin stared at him for a few seconds, and after leaving the empty plate he had on his lap on the bedside table next to him, he hesitantly lied down. Hugging his pillow again, Gen eyed Senku for a second longer before closing his eyes.

The blond stared at him for a few seconds before sitting back, leaning against the wall and turning on his phone.

“Have you talked to your father?” Gen asked, still with his eyes closed.

“He hasn’t been picking up his calls, so he must be busy.” The blond answered, staring at his phone. “Sleep.”

Gen shifted on the bed, getting slightly closer to him. “Wake me up for lunch.” He muttered, pressing his face against his pillow.

The blond hummed in acknowledgement, but didn’t say anything else.

 

———

 

Gen thought Senku was a calm person. He had always seen the blond reading or studying, so he had wrongly assumed he would be the same while studying science.

He had been trying to sleep for two hours and a half now, and the blond hadn’t stopped getting up, checking his bags and boxes, taking random things out, going back to read something on his phone, taking out a notebook and checking something there, tinkering with a few of the things he’d spread all over the floor…

“Can’t you just sit down and relax?” Gen groaned, covering his face with his pillow.

“I am relaxed.” Senku said, eyes fixed on whatever he was doing.

“Taiju once said he spends hours scrolling on his phone. Why aren’t you the same?” The Slytherin pouted.

Senku chuckled. “Because I get bored. I see scientific experiments and want to make them myself.”

“That doesn’t mean you have to do them now.” Gen sighed, sitting up on the bed and staring at the other. Senku was studying a piece of plastic attentively.

“It’s almost lunchtime anyways.” The blond finally looked over at him, and Gen pouted again. “Are you really not going to get out of bed for the rest of the day?” The Slytherin shook his head, and Senku sighed. “So you want me to bring you lunch here too?”

“Please,” Gen pouted.

The blond left the piece he was looking at on the floor before standing up and walking over to the bed.

“Why are you feeling like this today?” He asked, voice soft and worry in his eyes.

Gen dropped back down on the bed and turned away from Senku. “I don’t want to talk about it.”

The blond stared at him for a few seconds, weighing his options. He could get into bed and cuddle him just how Ukyo said he should do, or he could go get lunch and come back hoping he’d feel better after a while.

Although he really didn’t mind the prospect of the first option, Senku turned around and sighed.

“I’ll go get lunch, then.”

 

 

———

 

They had been silently eating for a while now, both of them sitting on the bed. Gen sighed and left his plate on the bedside table before lying back down.

“It happened on this day.” Gen said suddenly.

Senku looked over at him, confused. “What?”

“The reason why I can see Thestrals. It happened on this day, five years ago.”

The Ravenclaw’s eyes met Gen’s, heart clenching when he realised his eyes were shining with unshed tears.

Senku slowly left the plate on the floor before shifting closer to Gen, putting away the pillow that was placed between them. The Slytherin looked up at him before wrapping his arms around Senku’s waist and pressing his face against his chest.

“I’m sorry.” The blond whispered, rubbing Gen’s back.

“It’s okay.” He closed his eyes and tried to concentrate on the feeling of Senku’s chest raising and falling with every breath, the sensation of wanting to cry slowly fading away. He swung a leg over Senku’s, trying to get more comfortable.

Gen was surprised when the blond didn’t even flinch. He pressed his face against Senku’s chest to hide his smile.

The blond looked down at him before bringing his hand to Gen’s hair, brushing his bangs away from his face carefully before grabbing his phone and trying to distract himself, not wanting to move and disturb the Slytherin.

After a few minutes like that Gen fell asleep, the exhaustion from staying up all night too much for him.

Chapter Text

Gen knew he wasn’t going to be so lucky as to wake up still clinging to Senku’s body, but when he slowly opened his eyes and found out he was alone in the bed he couldn’t help but feel a bit sad.

He sat up on the bed, rubbing his eyes, eyes scanning all over the infirmary, looking for the blond.

“Where are you?” He asked in a whisper, getting out of bed and hissing when his feet came into contact with the cold infirmary floor. Gen hurried to grab a pair of socks.

After putting on a sweater and the Slytherin tie on he walked over to the door, opening it just a crack and peeking outside. The hallway was empty. He sighed.

A small sound made him turn around, jumping when he saw Senku standing right behind him. He pressed a hand to his chest, which was beating fiercely. “Don’t do that, oh my god.”

“I was just taking a shower.” Senku shrugged with a smile.

The Slytherin’s eyes drifted over to his hair, and he frowned. It was down, instead of its usual spiky style.

“Why is your hair looking like this?”

“It’s wet.” The blond muttered before turning around and walking over to his clothes, putting his Ravenclaw tie on. He could feel Gen’s gaze on him. “What?”

Gen walked closer to him. “Do you use magic to style it upwards?”

“…No. It just dries up like that.” The Slytherin tried to reach over and touch his hair, but Senku dodged him. “Forget it.”

The other pouted, his eyes following Senku while he organised all the things that were scattered on the floor.

“We should go to have breakfast.” The blond turned around to look at him once he put on his shoes. Gen was still staring at him. “What?”

“I want to touch it.” He stretched his arm towards him again, but before his hands touched his hair Senku ran out of the infirmary. It took him a second to chase him.

“No!” Senku exclaimed with a smile, sprinting towards the Great Hall.

“Please!” Gen pleaded, trying his best to catch up to him. He was barefoot, but the thick dark red rug covering the hallway floors made it not as painful as he’d expected.

He finally caught him, throwing himself on top of Senku. They both fell on the floor with a loud thump and rolled over, with Gen lying on top of the blond.

“You run too slow.” The Slytherin whispered. Both of them were panting, and he could feel Senku’s heart beating against his chest. He brushed the blond’s hair away from his face slowly.

Senku sighed, but didn’t push his hand away. Instead, his own hands found their way to Gen’s waist, keeping him in place. His gaze drifted to the Slytherin’s lips, which were slightly parted.

As if in instinct, he leaned up towards them, wanting to kiss them—”

“I know it’s the holidays, but you shouldn’t run in the hallways.” Kaseki’s voice made them both startle.

Gen practically jumped away from Senku and sat on the floor, face completely blushed. He looked over at the headmaster, who was entering the Great Hall without looking at them.

“Breakfast is served.”

 

———

 

“Shall we duel?” Gen asked suddenly, putting down his Charms book and looking over at Senku.

The blond left whatever he was doing with a microchip and turned around to frown at him. “What?” He asked confused.

Gen got off from the windowsill he’d been sitting on and walked over to him. “I want to know how powerful you are. Do you have your wand?” He asked, looking down at him.

The blond sighed and turned his attention back to the chip, attaching it to some cables. He didn’t give an answer.

“I’m bored.” Gen whined, folding his arms.

“And that’s why you want to duel me?” Senku asked in a monotone voice.

“Are you by any chance scared of losing?” Gen teased.

The blond scoffed, leaving the parts of the robot on the floor before standing up. Gen took a step back and smiled at Senku, who raised his eyebrows.

“Come on, get your wand.” He lazily rolled up his sleeves.

Gen smiled. “Are you trying to look tough?” The Slytherin asked, amused, taking his wand from his pocket and pointing it towards Senku.

Expelliarmus.”

Senku was hoping for Gen’s want to fly away from his hand, but the Slytherin effortlessly kept his stance, his smile growing bigger by the second.

“Trying to knock me out of the duel with some wandless magic, really?”

The blond tightened his jaw and took his wand out from his pocket, now really into the duel. “I think we should take it outside.”

Gen grinned and lowered his wand, excited. “Okay!”

He was getting more irritated by the second. He knew Gen was powerful, but he hadn’t paid much attention to him in the classes where they had to use magic, so he didn’t know to what extent he was going to be able to duel against him.

Senku followed him to the courtyard, glaring at Gen, who happily hummed all the way there.

He finally turned back to look at the Ravenclaw. “Ready?” Senku nodded, but before he could saw anything, Gen pointed his want towards him. “Expelliarmus.”

The Ravenclaw’s wand flew away from his hand, and he was pushed back.

Senku tightened his jaw, glaring at Gen.

“Oh, you couldn’t even dodge that?” The Slytherin cooed at him.

He walked over to retrieve his wand, feeling his blood boil. “Again.” He spoke, pointing his wand at Gen again.

Expelliarmus.” The Slytherin put even more strength on the spell this time, making Senku fly back and land on the grass with a small thump.

Senku stood up and took his wand again, ready.

“Again?” The blond nodded. “Expelliarmus.” His wand flew away from him once again. Gen sighed, teasing. “If you don’t start fighting back I’m going to get bored again.”

The blond glared at him, dusting off his clothes. “You’re a cocky bastard.”

Gen grinned, sitting down on the grass and folding his arms. “Come on, I’ll let you throw the first spell.”

Senku took his wand once again and pointed it towards him.

Expelliarmus.” A red light shot towards Gen, who muttered something under his breath.

A white light connected with the tip of the red one, fighting against Senku’s spell.

“I’m not even using half of my strength.” Gen sighed, resting his chin on one hand while the other held his wand.

After a few seconds where Senku tried his best to gather all of his strength to fight back Gen made his wand fly away once again. The blond sat down on the grass, panting.

“So that’s why you wanted to duel with me.” He finally said, breathless.

The Slytherin stood up and walked over to him, offering Senku his hand to help him stand up.

“You broke free from the stone quite easily, so I was curious. Did you use wandless magic?”

“Yes. I’m usually better at using spells against things instead of people, though.” He said, wiping the sweat off his forehead.

Gen smiled and dusted off the blond’s shoulders, pleased with himself. “You can go back to building your robot now.”

Chapter Text

Senku was reading an article on his mobile phone when his father called. He instantly stood up and picked up.

“Dad?” His gaze drifted back to Gen, who had looked up from the book he’d been reading.

“Hi hi! How are you? Sorry for not being able to call back sooner.”

Senku’s body relaxed when he heard his father’s voice. He walked out of the infirmary to have a bit of privacy.

“It’s okay. I’m fine. How are you?” He asked, nervously pacing down the hallway.

“Training it’s getting crazy. If I can, I’ll scan all the books and things we have to learn so you can read them.” Byakuya said with a tired sigh, although Senku noticed the happy edge to his voice. “We’re going to spend Christmas all of us together, so we aren’t as sad for not being able to be with our families.”

“That’s great.” The blond mumbled, opening the Potions classroom door and peeking inside.

“How are your holidays going so far?” Byakuya asked.

Senku made his way to a potions book lying on the teacher’s desk, distracted. “It’s going fine. My friend literally petrified me during the first day, though.” His father barked a laugh on the other line, and the blond chuckled. “It’s not funny.”

“What’s your friend’s name? Are they someone I know?”

“No…” Senku opened a cabinet to check if the ingredients he needed for the recipe he had just checked on the book were there, grinning when he spotted everything. “His name’s Gen. You’d like him.”

“Maybe he can come in summer? Where does he live?”

Senku froze, and slowly closed the cabinet. “I— Um. I don’t really know. I’ll ask him later.”

“Is he a Ravenclaw too?” Byakuya asked.

“No,” He shook his head as if his father could see him. “He’s a Slytherin.” He walked over to the window. It was already dark.

“Those are…?”

The blond chuckled. “The snaked.”

“Oh! Okay.” Byakuya chuckled too, then sighed. “I have to go make dinner now. I’ll try calling you again tomorrow, okay?”

“Okay, take care.” Senku walked away from the window and checked the potions book once again, rereading over it.

“Love you! Bye!” His father exclaimed before hanging up.

Senku unlocked his phone and after taking a picture of the recipe, he walked out of the classroom.

It was time to get his revenge on Gen.

 

———

 

“My dad asked about you today.” Senku said, taking a bite of his food and looking at Gen.

The Slytherin frowned. “What did he ask?”

“Where do you live?”

Gen sighed, leaving his knife and fork on the plate before answering. “London. Why?”

“He said you could come over in summer.” The blond shrugged, taking another bite and trying not to sound strained, nervous.

The other almost choked when he heard that. He started coughing, and took a sip of his water to calm down, feeling his face blush. “Where do you live?” Gen asked, taking a bite of his food and trying to stop from blushing even more.

“Edinburgh, but my dad is living in London for his training now.” Senku answered, staring at Gen.

He hummed. “I’d love to go, but I usually work over the summer to save up money.”

“I thought you were rich.” Senku said.

It made Gen look up, eyebrows furrowed. He pushed his plate away, already feeling full, and stared at the blond. “Why did you think that?”

“I don’t know— Well, you’re a pure-blood and Yuzuriha told me your mom’s quite famous, so I just assumed it.” Senku shrugged, still eating.

“My family’s rich, yes. I used to live in a mansion on the outskirts of London, but now I live with my grandma. She doesn’t have much money, so I pay for my expenses.”

“And why did you move away?” Senku asked, looking up at him.

Gen tightened his jaw and lowered his gaze. “I didn’t like living there, and I was alone most of the time. My mom is always busy.” He sighed.

“And your dad?” Senku finally finished his food and left his plate aside, now his attention completely on Gen.

“He’s gone.” The Slytherin shrugged, still avoiding the other’s gaze.

“Gone?”

Gen pinched the bridge of his nose and sighed. “Shall we go to sleep?” He asked, standing up.

Senku didn’t say anything, just stood up and followed him out of the Great Hall in silence.

Only when they were halfway through their way to the infirmary did Senku speak, softly calling for him. “Gen.”

The Slytherin stopped and turned around in the middle of the hallway. “What?”

Senku walked up to him and wrapped his arms around his neck, pressing Gen’s face against his chest.

He blushed, eyes wide open in surprise and embarrassment. It took him a few seconds to hug the blond back, wrapping his arms around Senku’s waist, clinging to him tightly.

They stayed like that for a few seconds, the Ravenclaw’s cheek resting on Gen’s head, until the blond backed away. “Let’s go.”

 

———

 

Gen stared at Senku while the blond prepared his own bed, pushing two infirmary beds together and throwing his duvet on top of them both. Lower lip jutting out in a small pout, he hugged his pillow, fighting against the part of him that wanted to lie down next to him again.

The Slytherin almost suggested sleeping together again, the memory of Senku’s warmth clouding his mind.

Still, he didn’t have any good excuse to convince him, just the need to hug him again.

Senku was hating every second of it. He could feel Gen’s gaze on him, and he just wanted to walk over to him and hug him close until they both fell asleep.

He had been trying to find a reason to sleep on the same bed as the Slytherin for a few minutes, but he didn’t have any. And he wasn’t brave enough to just say it.

“I’m cold.” Gen mumbled. Senku instantly turned to look at him.

“…Do you want a hoodie or something?” He asked hesitantly, staring at the way Gen’s arms tightened around his pillow before he answered.

“Yes, please.”

Senku walked over to the pile of Gen’s clothes on the side of the infirmary, when the other spoke again.

“Yours.”

The blond stopped for a second, processing the words before he turned towards his own clothes, trying not to blush too much. He tossed a navy blue hoodie over to Gen, who caught it and instantly put it on, a relieved sigh escaping his lips.

It smelled like Senku, and that was enough for him for now.

“Better?” The blond asked, walking over to his new makeshift bed and lying down on it. Gen nodded, a small smile on his lips. “Then let’s go to sleep.”

“Goodnight,” Gen said, putting the hood on and lying back down on the bed.

“Goodnight,” Senku said back before turning around, trying to ignore the fact that he was blushing at the thought of Gen sleeping with something of his own on.

Chapter Text

Gen told himself he should start getting used to waking up and not seeing Senku, but opening his eyes to two empty beds instantly put him in a bad mood.

Turning around, he covered his face with Senku’s hoodie, closing his eyes again and trying to fall back asleep.

He was close to dozing off once again when he heard a loud shriek, coming from the courtyard. Gen jumped out of bed and looked out the window, suddenly wide awake.

A Thestral was standing in the middle of the courtyard, trying to catch a bird. The Slytherin smiled and after hurrying to put on some shoes, a thick coat and Senku’s Ravenclaw scarf on he rushed out of the infirmary.

On his way to the courtyard he dropped by the castle’s kitchen, grabbing a fresh piece of meat before going outside.

“What are you doing here?” He asked in a whisper before throwing the piece of meat at the creature. It caught it easily, and happily ate it in a few bites. Gen stepped closer to it and patted the Thestral’s head softly. “Did you get lost trying to eat the bird?” He asked, smiling when the creature rubbed its head against the Slytherin’s body, asking for more.

“Breakfast is ready.” Kaseki’s voice startled him.

He turned around to look at the headmaster, who was wearing a worn-down tracksuit. Gen assumed he was in his pyjamas too.

“Have you seen Senku?”

Kaseki shook his head. Gen sighed, turning his attention back to the Thestral.

He heard the leaves crunch when the headmaster stepped closer. “Gen, you know I love you as if you were my own grandson.” Kaseki rested a hand on his shoulder, making the Slytherin turn around to look at him, confused by his tone. “And you really don’t have to listen to what I’m about to say right now, but I feel like I have to say it.”

Gen’s heart started beating harder, but he slowly nodded, encouraging Kaseki to keep talking. He knew the headmaster pretty well, so it was easy to deduce whatever he was going to say next wasn’t going to be nice. Dread pooled in the pit of his stomach.

“I know you like that Ravenclaw boy but… I want you to think about how different you two’s backgrounds are. Imagine what your mother will say when she finds out he was raised by a muggle and doesn’t really care about magic altogether.”

The Slytherin took a step away from Kaseki, frowning at him. The Thestral huffed, as if it was understanding the conversation and he wasn’t liking it either.

“Do you even think I care about what my family would say?” His voice trembled a bit, and he noticed the way Kaseki’s expression turned to one of concern.

“Of course not, but what I wanted to say was—”

“I appreciate your concern, Kaseki, but I think I can handle my family just fine. I won’t choose who I like and who I don’t based on their upbringing, or their opinion on magic.” He adjusted the scarf around his neck, looking back at the headmaster. “If you’ll excuse me now,”

Turning around, Gen walked back inside the castle without waiting for a response, hurrying to the infirmary.

The pressure he felt inside his chest disappeared as soon as he saw Senku leaning back against the door, arms folded and waiting.

“There you are,” He smiled, and the Slytherin couldn’t help but smile back. Senku stepped closer to him, adjusting his scarf and pulling the hood over his head. “You look cold. Where were you?”

“There was a Thestral in the courtyard, so I went outside to feed it.” Gen answered, forcing himself not to lean towards the other’s touch. “Where were you?”

“I had to go to the Ravenclaw tower to get something for my robot.” Senku lied, trying not to smile. “Breakfast?”

“Yes, please. I’m starving.” Gen said with a smile, and followed the blond to the Great Hall, both of them silent.

The Slytherin looked up and studied Senku’s face. He wondered how his childhood was, if his father and he spent the whole time doing weird experiments or if he’d been introduced to magic from early on. Gen couldn’t imagine a moment where he hadn’t known about magic, and part of him wondered how that felt.

“What are you staring at?” Senku asked, glancing at him.

Gen tore his gaze away, blushing. “Nothing.”

 

———

 

“I have something for you.” Senku said, trailing after Gen out of the Great Hall after lunch.

The Slytherin frowned and stopped, turning to him. “What?”

“Come.” Senku softly grabbed Gen’s wrist before guiding him upstairs, to a random hallway. “While I was looking for some parts for my robot in my room, I found this. “

The blond took out two cola bottles from his backpack.

Gen frowned and took one of them, examining it with a frown. “What is this?”

“It’s a really famous beverage in the muggle world. I think you’ll like it.”

The Slytherin looked up at Senku again, who smiled widely at him. He pursed his lips, hesitating. “Are you sure it’s not a poison or something as payback for me petrifying you?”

Senku chuckled and shook his head. “Why would you think that? I promise it isn’t.”

Gen held the other’s gaze for a few seconds, and after another moment of hesitation he finally opened the bottle with a sigh.

He took a sip of the beverage, almost throwing it up right away. “What the hell is this?!” Gen coughed, face twisted with disgust.

“You have to drink it all. If you don’t, you won’t be able to savour it completely.”

The Slytherin frowned at him before taking another long sip of the beverage, finally finishing it. He shook his head, absolutely disgusted with the taste, before glaring at Senku.

“This is gross. I hate it.”

The blond stared at him, grinning.

Gen frowned, squinting at him. “What the hell is so funny?”

Senku kept staring at him, an amused smile on his face, while the Slytherin’s face slowly started to change. Firstly, some whiskers magically appeared on his cheeks, his nose turned pink and slowly morphed into a triangle. It only took a few seconds until the Ravenclaw wasn’t staring at his friend anymore, but at a small black and white creature with dark blue eyes that were still glaring at him.

The blond’s smile grew bigger, satisfied with the knowledge that he’d brewed the potion correctly.

He’d turned Gen into a cat.

Chapter Text

Senku grinned, arms folded and looking down at Gen.

“You’ve drunk every last bit of it, so I assume you’ll be like this for a few hours.” His new cat friend stared at him silent, his dark blue eyes fixed on him. Gen’s tail was slowly swishing side to side, tentative. “What? You have a cat’s brain now and can’t understand me?”

The blond leaned forward, kneeling in front of Gen, and with a low hiss the Slytherin pounced at him, trying to scratch his face.

Senku fell back on the floor, Gen’s cat claws digging on his sweater.

“Don’t scratch me!” He shrieked, trying to grab Gen, which resulted in the Slytherin managing to bite and scratch his hands. “Ouch— Stop!”

Gen finally jumped off Senku, hissing at him.

It took a second for him to regain his composure, the scratch on his hands itching uncomfortably. He finally sat up, grinning again at Gen.

“What are you so angry for? Don’t you like cats?” Gen jumped at him again, this time ready to ruin his face, but Senku managed to dodge him, laughing. “Not the face!”

Gen stared at him for a few seconds, eyes slightly squinted as if he was thinking what to do next, before jumping on the windowsill and staring out the window.

The blond grabbed Gen’s clothes before standing up and walking over to him.

“Let’s go.” He sentenced, reaching to take him. The Slytherin instantly reacted, claws digging into his shoulder through the sweater, eyes glinting with satisfaction when Senku yelped. “Stop trying to attack me!”

With one last low hiss, Gen jumped away from him and hurried down the hallway, leaving Senku standing there, half in pain and half confused.

“…Gen?”

 

———

 

“Fuck,” The blond muttered under his breath, hurrying the steps up to the library, already feeling out of breath. He’d already looked all over the patio and the first floor, and Gen was nowhere to be seen. “Where the hell are—” His voice trailed off when he opened the library door and found a cat lying on one of the bookshelves.

Slowly stepping closer to it, Senku groaned when he saw the fur. “You’re not him,” He sighed, not moving when the cat rubbed his body against the blond’s arm. “Have you seen another cat, little guy?”

From the way the white cat stared at him, Senku knew he wasn’t magical and capable of answering his question.

The library was too big for him to look through, so he just decided to move to the upper levels, rushing around the hallways in search of Gen.

By the time he ascended up to the Ravenclaw tower he was absolutely breathless, and his right side hurt from running too much. Still, there wasn’t any other option, and he couldn’t enter the other houses, but maybe—

A small part of him hoped that he’d find Gen there, maybe lounging around the common room.

He sighed loudly when he didn’t find him on the sofas, looking around at every windowsill to make sure he wasn’t there either.

Blaming himself for being stupid enough to think he’d go to Ravenclaw, Senku decided to go up to his bedroom anyways just to get a thicker coat and go out to the castle grounds again to look for him.

He went up slowly, already drained of energy, and sat down on his bed with another sigh.

Maybe he should shower. He was sweating from all the running.

Senku jumped when he felt something move against him, and noticed the lump under his bedsheets.

His heart skipped a beat when cat Gen jumped onto the floor, looking up at him with big, innocent eyes.

The blond hadn’t even noticed how tense he’d been until his muscles relaxed, a small sigh escaping from his lips at the sight of Gen.

“My god, finally,” He muttered, reaching out of the Slytherin. “I was looking all over for you.”

Thankfully Gen let him pick him up, placing the cat on his lap and rubbing his head softly.

For a second, he thought how weird that was. Senku forced himself to push the thought out of his mind.

Gen was looking up at him, tail slowly swishing from side to side innocently.

He pressed him against his chest, standing up. “Let’s go back to the infirmary— Ow! Don’t bite me again!” He exclaimed when the Slytherin’s fangs dug into his hand, but at least this time he didn’t jump away.

Enjoying the feeling of the cat’s warmth against his chest, Senku made his way back to the infirmary, trying his best to ignore how hard Gen was still biting him, although his jaw was slowly relaxing. 

If he was turned into a cat, he’d probably bite him too.
