Denki was in a foul mood when he flopped down on Eijirou’s bed. His tutoring session had been going so well, he was no longer nervous about being a mentor to a (cute, overexcited, eager to learn) first year, and he sometimes helped her twin brother as well. Denki loved the third year–first year mentor system that U.A. had implemented in their second year, he liked the kid who was assigned to him based on their Quirks’ compatibility, and they even bonded over their shared favorite bands and groups. It was a mystery why it was him who got the girl twin who conjured snow storms instead of the boy who controlled rain, but since they were sort of a package deal he often had to work together with Honenuki from Class B.
Eijirou put down the textbook he was reading—Denki hadn’t even started on his homework—and pushed his swivel chair backwards, maneuvering himself so that he was right next to Denki’s head. Denki smashed his face into Eijirou’s pillow and groaned. There were fingers in his hair, gently massaging his scalp, rubbing circles on his temple.
“Bad session?” Eijirou asked. Denki shook his head.
“‘Kay,” Eijirou said, not stopping the light caresses. “Tell me when you’re ready.”
Denki turned his head to the side so that Eijirou’s hand fell onto his cheek. Eijirou leaned down and pressed a chaste kiss on Denki’s forehead. He didn’t withdraw his hand, just continued to play with his hair.
“I got a confession.”
The fingers in his hair stilled for a second. “You got a what?”
“Kid asked me out and I froze. Everything was going so well until the kid asked me to stay behind. I thought he had a question he was too embarrassed to ask me in front of his sister. He started talking about how he’s glad I’m his sister’s mentor and I was so happy, you know? I was thinking ‘that’s it, you’re doing a good job’ and then he confessed he has a crush on me.”
Eijirou hummed and scooted closer to Denki, but he didn’t speak.
“I didn’t know what to say, but that didn’t even matter because he was rambling. He told me the only reason he felt brave enough to confess is that my two guy best friends are dating. And I just— When I told him we’re in a polyamorous relationship he didn’t believe me.”
He reached out and grabbed Eijirou’s hand. Eijirou gave his hand a gentle squeeze and laced their fingers together.
“Why does everyone—” Denki squeezed his eyes shut, sighed, and started again. “Does everyone think you guys are out of my league? That I’m the third wheel to your power couple? Just a friend tagging along?”
“Denki.” Whenever Eijirou said his name in that soft tone, Denki’s stomach fluttered. “We love you.”
“I know. But why does this keep happening every damn time? You and I are way more affectionate in public than Katsuki and you. I just don’t understand.”
Eijirou shook his head.
Eijirou dug out his phone from the pocket of his shorts. “I’ll text Katsuki.”
“No, don’t! Let’s not bother him. He should be done with his own mentoring session soon.”
But Eijirou didn’t listen to him, because Denki could see his thumbs moving rapidly on the screen of his phone.
“Sit up,” Eijirou ordered, waving a hand at him. Denki pushed himself up with a groan and leaned against the wall. Eijirou crawled beside him and put his arms around him. Denki scooted closer and rested his head in the crook of Eijirou’s neck.
“It shouldn’t even matter,” Denki whispered. “But it bothers me and I hate that it does.”
Eijirou tightened his hold on Denki, and pressed a kiss on the top of his head. He opened his mouth to say something, but the loud bang the door opened with cut him off.
“How did you get here so fast?” Denki asked, hiding a smile.
“I was already on my way. The brat asked me to cut the session short. Told her this is the first and last time she pulls shit like this on me last minute.”
Denki felt the mattress dip on the other side of him and a few beats later there were a second set of arms around him.
“You’re an idiot if you doubt our feelings for you.”
“I’m not. Doubting them I mean.”
Denki smiled and raised his head from under Eijirou’s chin to knock it lightly against Katsuki’s. Katsuki turned his head, his lips finding Denki’s before he pulled away.
“I’ll fucking give an interview if you guys think that would help.”
Denki shook his head. “Leave it. I’ll get over it soon. It just hurts a little bit when it happens.”
They kissed again, lazy, open mouthed kisses. When they broke apart Denki turned to Eijirou to kiss him as well. Katsuki’s and Eijirou’s kisses were different, but they left Denki with that familiar warm feeling in his chest all the same.
The three of them stayed like that for a while, and it wasn’t long before Katsuki dozed off, his head falling onto Denki’s shoulder at an awkward angle. Denki wiggled around to make it more comfortable for him without waking him up, and ended up sprawled in Eijirou’s lap.
This is fine, Denki thought, more than fine.
