Geonwoo was always the jealous type, no matter how hard he tried to hide it.
He could mask it behind that calm, efficient demeanor, the one that made him the group's reliable fixer, the guy who handled schedules and crises without breaking a sweat. But underneath, it simmered like a low flame, ready to flare up at the slightest provocation.
And Jiahao? Jiahao was the spark that could turn it into a wildfire.
It had been like that since the beginning, even before they started dating.
During those grueling debut preparations, Geonwoo had watched from the sidelines as Jiahao charmed everyone with his effortless sweetness, his pretty smiles that lit up the practice room like spotlights.
He remembered the confession letter from Junseo, how it had landed like a punch to his gut when he overheard the whispers. Jiahao had rejected it, of course, with Leo and the others backing him up, but the mere fact that someone else had dared to put it in writing had ignited something possessive in Geonwoo. He hadn't acted on his feelings then; the group came first, always.
But once promotions wrapped and they found stolen moments in empty studios or late-night walks, everything changed. Jiahao became his, in secret, and Geonwoo guarded that secret like a dragon hoarding gold.
He didn't mind the secrecy, not really. It kept things uncomplicated.
The other members didn't need to know; it might distract them, or worse, make them worry about focus.
Leo especially, Geonwoo respected him as a leader, but the way he doted on Jiahao, like an overbearing best friend or something closer, always set Geonwoo's teeth on edge. Leo knew Jiahao inside out, from their undeniable intimate experiences that predated the group. Leo was a kind of brand that Jiahao always had since the survival program. He was Jiahao's anchor, the one who could calm him with a touch or a word.
Geonwoo told himself he was fine with it. Leo didn't know about them, so what harm was there? But deep down, it gnawed at him. What if Jiahao didn't need him as much because he had Leo?
That night, coming back from the radio schedule with Sanghyeon, the jealousy hit him so hard.
He was exhausted, muscles aching from the forced smiles and endless chatter, but all he could think about was texting Jiahao, maybe sneaking into his room for a quick goodnight kiss if everyone else was asleep.
Sanghyeon mumbled something about crashing into their shared bedroom and disappeared down the hall, leaving Geonwoo to lock the door.
Geonwoo kicked off his shoes, rolling his shoulders, and headed toward the living room, drawn by the faint glow of the TV.
And there it was: Jiahao, drunk and clingy, draped over Leo like a living blanket.
Geonwoo's stomach twisted. Jiahao's head was nestled under Leo's chin, his arm slung across Leo's waist, fingers loosely gripping the fabric of his hoodie.
Leo's hand rested on Jiahao's shoulder, casual, protective, the way it always did.
But tonight, with empty soju bottles scattered on the table and Jiahao's cheeks flushed that adorable pink, it looked intimate. Too intimate.
Jiahao giggled at something Leo said, nuzzling closer, and murmured, "Lele, you're so warm."
Leo chuckled softly, patting his back. "Easy, baby. Don't fall off the couch."
Geonwoo's vision narrowed. His heart pounded, a mix of anger and hurt surging through him. How could Jiahao be so oblivious? Or was he? Did he enjoy the attention, the way Leo indulged him without question, calling him baby like it was nothing?
Geonwoo clenched his fists at his sides, forcing himself to breathe. He wasn't the type to make a scene, not in front of Leo, not when the group dynamic was so fragile. But seeing Jiahao like that, all soft and pliant for someone else, made him want to drag him away and remind him exactly who he belonged to.
It wasn't rational; he knew Leo was just being a friend, barely tipsy himself while Jiahao was clearly over the edge. But rationality didn't matter when jealousy clawed at his chest like this.
"Hao-hyung," he said, his voice coming out lower than intended, edged with command.
Jiahao's head lifted slowly, eyes blinking in that hazy, drunken way. When he saw Geonwoo, his face lit up, a slow, sweet smile spreading across his lips. "Geonwoo-yah, you're home."
The way he said it, like Geonwoo was the best thing he'd seen all night, softened the edge a little. But not enough. Leo glanced up, his expression neutral, almost amused. "Hey. Long day?"
Geonwoo ignored him, his focus laser-sharp on Jiahao. He crossed the room in a few strides, heart racing with a possessive urge he couldn't quite suppress. "Come here, hyung."
Jiahao pouted, that bratty little lip jutting out, but he started untangling himself from Leo. It was slow, reluctant, like he didn't want to leave the warmth.
Leo patted Jiahao's back gently. "Go on, baby. Sleep it off."
Geonwoo bit back a snarl. Sleep it off? As if Leo had any right to dismiss him like that, or to call Jiahao baby so casually.
But he kept his cool, reaching out to steady Jiahao as he stood, wobbling on his feet.
The moment Jiahao leaned into him, arms looping around Geonwoo's neck, some of the tension eased. "I smell weird because of the soju– was waiting for you," Jiahao mumbled, burying his face in Geonwoo's collarbone. "Missed you."
Missed him? Then why the hell was he cuddling with Leo?
Geonwoo wrapped an arm around Jiahao's waist, firm and unyielding, steering him down the hallway.
Jiahao giggled against his throat, lips brushing skin in accidental kisses that sent sparks down Geonwoo's spine. It was maddening, how Jiahao could flip from innocent to tempting without even trying. The rosy, lavenderish scent of him filled Geonwoo's nose, a mix of his favorite body wash and the faint trace of soju, making his head spin. Geonwoo kicked Jiahao's bedroom door shut, the lock clicking with finality.
This was his space, their secret haven, and tonight, he needed to reclaim it.
He backed Jiahao toward the bed, hands on his hips to keep him steady. Jiahao went down willingly, pulling Geonwoo with him until Geonwoo was hovering over him, knee planted between Jiahao's thighs. The position was intimate, charged, and Geonwoo's pulse thrummed with a mix of desire and frustration.
Jiahao beamed up at him, eyes bright despite the alcohol. His fingers traced Geonwoo's jaw, soft and affectionate. "Hi."
Geonwoo caught his wrist, pinning it to the bed. The touch grounded him, but it also ignited something darker. "You were all over Leo."
Jiahao blinked, processing slowly. Then his mouth curved into that teasing, cat-like smile Geonwoo both loved and hated. "Was I?"
"You know you were." Geonwoo's voice was tight, memories flashing: Jiahao's giggles, the way he'd rubbed against Leo like a contented kitten, calling him Lele. It hurt, more than he wanted to admit. Was he not enough? Did Jiahao need Leo's comfort because Geonwoo wasn't around? Was that how it was every time?
Jiahao arched under him, hips shifting in a way that was pure invitation. Geonwoo's breath caught, desire warring with jealousy. "He was being nice to me. Lele and I– just shared a drink… was keeping me company… and you. You're late."
Late. As if that excused it. Geonwoo's free hand slid up, fingers curling loosely around Jiahao's throat. He could feel the rapid pulse there, matching his own. "I don't like it when you let other people touch you and especially when you touch them first."
Jiahao's breath hitched, pupils dilating. "Are you mad?"
"I am."
There was a little room for another sharp intake of breath.
"Then do something about it, my angry hot boyfriend."
The challenge in his voice snapped something in Geonwoo.
"So you do remember that I'm your boyfriend?"
Jiahao gave him a very flirty, feline smile. He wasn't making this any better for himself, honestly. He'll regret that later. "Don't be ridiculous. Just punish me, oppa."
Geonwoo felt his skin crawl. He leaned down, their mouths inches apart. "Behave."
Jiahao laughed, soft and defiant. "Make me."
Geonwoo paused, staring down at him.
Jiahao looked so beautiful like this, flushed, eyes sparkling with mischief, body yielding yet teasing. It made Geonwoo's chest ache with how much he wanted him, needed him. But the jealousy lingered, a bitter taste. He thought back to their first kiss, stolen in a dark practice room after everyone left. Jiahao had been shy then, sweet and unsure, but he'd melted into Geonwoo like he was made for it. That memory fueled him now. He tightened his grip on Jiahao's throat, just enough to assert control without hurting. "Can't really say no to you, can I?"
He crashed their mouths together, hard and demanding, pouring all his frustration into the kiss.
Jiahao responded instantly, tongue curling against his, a surprised moan vibrating between them. Geonwoo bit his bottom lip, tugging until Jiahao whimpered, the sound going straight to Geonwoo's core. This was what he needed, to remind Jiahao, to mark him in ways no one else could see.
Pulling back, Geonwoo watched Jiahao pant, eyes glazed with a new kind of haze. Satisfaction bloomed in his chest. "Hands above your head. Keep them there."
Jiahao hesitated, that bratty spark flaring again. Geonwoo's jaw clenched, did he have to push every time? But then Jiahao obeyed, stretching his arms up, fingers gripping the pillow. The arch of his back made his shirt ride up, exposing smooth skin that Geonwoo wanted to map with his hands, his mouth.
He dragged his gaze down Jiahao's body, slow and deliberate. Possessiveness surged through him like heat. Mine, he thought fiercely. All of this is mine. No one else gets to see him like this, vulnerable and wanting. "You looked so sweet on the couch," he murmured, fingers tracing the hem of Jiahao's shirt, pushing it higher. "All cuddled up. Letting him hold you. Calling him Lele while he called you baby."
Jiahao shivered under his touch. "Wasn't like that."
"Wasn't it?" Geonwoo's hand flattened on his stomach, thumb circling the navel in teasing strokes. He felt Jiahao's muscles tense, hips jerking involuntarily. The power of it, the way Jiahao responded to him, eased the jealousy a fraction. But he needed more. He needed Jiahao to understand.
"Geonwoo," Jiahao's voice was breathy, pleading.
"Shh." Geonwoo leaned down, lips brushing his ear. The rosy, lavenderish scent was stronger here, intoxicating. "You want to be pretty for someone tonight? Then be pretty for me."
He peeled Jiahao's shirt off, tossing it aside, then stripped his own. Skin on skin was electric; Jiahao sighed, long and shaky, legs parting to let Geonwoo settle between them. Geonwoo's heart swelled with a fierce tenderness.
This was what they had, moments like this, hidden from the world.
He kissed down Jiahao's throat, leaving slow bites that would bloom into faint marks by morning. Leo might see them, wonder, but he'd never know the truth. The thought sent a thrill through Geonwoo, a petty victory over his unspoken rival.
Jiahao squirmed, seeking friction, but Geonwoo pinned his hips with one hand. Control. He needed control tonight, to wash away the image of Jiahao with Leo. "Stay still."
A whine escaped Jiahao. "Please."
"You don't get to beg yet." Geonwoo's voice was calm, but inside, he was a storm, desire churning with remnants of hurt. Why did Jiahao have to test him like this? Didn't he know how much Geonwoo loved him, how he'd do anything to keep him? "You don't get anything until I decide you've learned."
Jiahao's eyes fluttered shut, nodding once, small and submissive. The shift pleased Geonwoo, a balm to his ego. He rewarded it with a slow grind of his hips, letting Jiahao feel his arousal. Jiahao's back bowed, a broken sound slipping out, and Geonwoo murmured against his collarbone, "Good boy. That's better."
From there, he took his time, drawing it out to savor every reaction. His hands explored Jiahao's body like it was new territory, even though he knew every inch by heart. Fingers traced ribs, teased nipples until they pebbled, dipped lower to unbutton jeans with deliberate slowness. Jiahao trembled beneath him, breaths coming in gasps, and Geonwoo's mind raced with thoughts: How could anyone else think they could have this? Jiahao was his anchor too, the one who made the chaos of idol life bearable.
The jealousy faded as desire took over, but he held back, teasing until Jiahao was a mess of pleas and whimpers.
He slid Jiahao's jeans down, along with his underwear, exposing him completely. Jiahao's arousal was evident, flushed and leaking, and Geonwoo wrapped a hand around it, stroking slowly, too slowly. Jiahao bucked into the touch, whining. "Faster, please."
Geonwoo stopped entirely, pulling his hand away.
"No. You take what I give you." His voice was low, commanding, the anger from earlier seeping back in. He watched Jiahao's face crumple in frustration, body arching desperately. Good. Let him feel it, the denial, the control.
Geonwoo leaned down, biting at Jiahao's inner thigh hard enough to leave a mark, soothing it with his tongue afterward. Jiahao gasped, legs spreading wider instinctively.
"Geonwoo, I need more," Jiahao begged, voice cracking.
"Not yet, hyung." Geonwoo repeated the process on the other thigh, then moved up, mouth hovering over Jiahao's length without touching. His breath ghosted over the sensitive skin, making Jiahao shudder. "You were so eager for Leo-hyung's attention earlier. Giggling for him. Nuzzling him. Think he could make you feel like this?"
Jiahao shook his head frantically. "No, only you."
"Prove it." Geonwoo finally took him into his mouth, but only halfway, swirling his tongue lazily. Jiahao moaned, hips trying to thrust up, but Geonwoo's hands held him down firmly. He pulled off after a minute, leaving Jiahao panting and on the edge. "Don't move."
He did this again and again, bringing Jiahao close to release only to stop, fingers or mouth withdrawing just as Jiahao's breaths turned ragged. Jiahao suffered under it, tears pricking at his eyes, body slick with sweat. "Please, Geonwoo, I'm sorry. I won't do it again."
Geonwoo's chest tightened at the sight, a mix of satisfaction and guilt. But the jealousy demanded this, this freaky edge where he pushed Jiahao to his limits, made him beg and break. He flipped Jiahao onto his stomach suddenly, pulling his hips up. "On your knees."
Jiahao complied shakily, forehead pressed to the pillow. Geonwoo prepped him slowly, fingers scissoring inside, curling to hit that spot until Jiahao was sobbing into the fabric. But again, he stopped short, withdrawing completely. "Who do you belong to?"
"You," Jiahao whimpered. "Only you."
Geonwoo stripped his own pants, positioning himself. "Remember that." He pressed in inch by inch, agonizingly slow, feeling Jiahao clench around him. Once fully seated, he paused, hands gripping Jiahao's hips bruisingly tight. "Don't come until I say."
He started moving, thrusts deep and measured at first, building to a punishing rhythm. Jiahao cried out with each one, hands fisting the sheets, body trembling on the verge. Geonwoo reached around, stroking him in time with his movements, but squeezed the base whenever Jiahao got too close. "Hold it," he growled.
Jiahao suffered beautifully, pleas turning incoherent, tears streaking his cheeks. Geonwoo's control was ironclad, fueled by the earlier rage, but underneath was love, the need to possess and protect. Finally, when Jiahao was a wreck, Geonwoo leaned over him, whispering, "Now. Come, hyung."
Jiahao shattered, body convulsing, spilling over Geonwoo's hand. The tightness pulled Geonwoo over the edge too, thrusting erratically until he filled him, collapsing together in a heap.
In the quiet aftermath, Geonwoo pulled Jiahao close, wiping his tears gently. The jealousy was gone, replaced by a warm contentment. Jiahao nuzzled into his chest, already drifting off. "Love you."
Geonwoo smiled faintly, pressing a kiss to his forehead. "Love you too."
"Don't be upset over Leo," Jiahao suddenly said, voice a little rough. "You know I just appreciate him so much for being here. He listens to me. He's a very good friend."
"I know," Geonwoo pressed another kiss to Jiahao's skin. "But you can't forget that you're mine, hyung. You're not Leo-hyung's, are you?"
He could tell that Jiahao wanted to laugh. "Of course not. I'm only yours."
Geonwoo let out a deep satisfied breath as for the next few momenrs, they both lay there, staring at the ceiling, thoughts settling.
He was jealous, yes, but Jiahao chose him every time.
Still, he would always make sure Jiahao wouldn't forget who he belonged to.
