Work Text:

The practice room was still buzzing with energy even though it was past eleven PM. Junwon leaned against the doorframe, arms crossed, watching through the small window as Jiwoon ran through the choreography one more time with his members. He’d been waiting for twenty minutes already, but he didn’t mind—he never minded when it came to Jiwoon.

What he did mind, however, was the way that kid kept touching his boyfriend.

Heeju. One of their members. Barely nineteen, with that stupidly perfect skin and that big ass smile that probably made all the fans squeal. Junwon had met him exactly once, briefly, and had immediately gotten a bad feeling about how comfortable the kid seemed around Jiwoon.

Now, watching Heeju drape himself over Jiwoon’s back, arms wrapped around his waist, chin hooked over his shoulder, Junwon felt his jaw clench so hard it hurt.

“Jiwoon-hyung, you’re so good at this part,” Heeju whined, and even through the door, Junwon could hear the aegyo in his voice. “Teach me again?”

Jiwoon laughed—that soft, gentle laugh he did when he was being patient with someone—and reset his position. “Okay, one more time. Watch my footwork here…”

Heeju practically plastered himself to Jiwoon’s side, fingers clutching at his hyung’s sleeve as he watched with exaggerated focus. When Jiwoon demonstrated the move, Heeju stumbled intentionally (or so it seemed to Junwon’s increasingly suspicious mind) and grabbed onto Jiwoon to steady himself.

Junwon’s phone creaked in his grip.

Finally, FINALLY, their manager called it a night. The members started gathering their things, and Junwon straightened up, schooling his expression into something neutral. He knew he was being ridiculous. He knew Jiwoon loved him. But knowing and feeling were two very different things, especially when some clingy teenager was all over his boyfriend like a koala on a eucalyptus tree.

The door opened and members started filing out. A few recognized Junwon and bowed politely—he’d been around enough times that they knew who he was. Then came Jiwoon, bag slung over his shoulder, hair damp with sweat, looking tired but breaking into a smile the moment he saw Junwon.

“Hyung! You didn’t have to wait, I told you practice might run late—”

“Jiwoon-hyung!” Heeju bounded out behind him, immediately attaching himself to Jiwoon’s arm. “Are you sure you can’t get dinner with us? Pleeease? I wanted to ask you about—oh.” He finally seemed to notice Junwon, blinking up at him with those ridiculous doe eyes. “Oh, hello, sunbaenim.”

“Heeju-ya, this is Junwon-hyung,” Jiwoon said, gently trying to extract his arm. “I told you about him, remember?”

“Ah, the actor-hyung!” Heeju’s grip didn’t loosen. “Jiwoon-hyung talks about you sometimes. Are you taking him home?”

“That’s the plan,” Junwon said, and he could hear the edge in his own voice even as he tried to keep it friendly.

“Aww, okay.” Heeju finally released Jiwoon’s arm, but not before giving him a quick backhug that made Junwon’s eye twitch. “See you tomorrow, hyung! Don’t forget you promised to help me with my vocals!”

“I won’t forget,” Jiwoon assured him with a pat on the head. “Go catch up with the others.”

Heeju bounced off down the hallway, and Jiwoon turned to Junwon with that soft smile still in place. “Sorry for making you wait. Ready to go?”

Junwon just nodded and started walking toward the exit. Jiwoon had to jog a little to catch up, and Junwon could feel his boyfriend’s questioning gaze on the side of his face.

“Hyung? You okay?”

“Fine.”

“You don’t seem fine.”

“I said I’m fine.”

They made it to Junwon’s car in silence. Junwon unlocked it with more force than necessary, and Jiwoon slid into the passenger seat with a small sigh. Once Junwon was behind the wheel, engine running, Jiwoon tried again.

“Did something happen today? Your audition—”

“The audition was fine.”

“Then what—”

“Does that kid always hang all over you like that?”

There was a beat of silence. Then Jiwoon let out a soft “oh” of understanding. “You mean Heeju?”

“Is there another kid who can’t seem to keep his hands to himself?” Junwon pulled out of the parking spot with barely controlled precision.

“Hyung.” There was amusement in Jiwoon’s voice now, which only made Junwon more irritated. “Are you jealous?”

“No.”

“You are! You’re jealous of Heeju!”

“I’m not—” Junwon cut himself off, jaw working. “He was practically glued to you.”

“He’s just affectionate,” Jiwoon said, and Junwon could hear the smile in his voice. “That’s how he is with everyone. It doesn’t mean anything.”

“Looked like it meant something to me.”

“Hyung.” Jiwoon’s hand found Junwon’s on the gear shift, fingers curling around it. “He’s just a kid. He’s four years younger than me—that’s like, I don’t know, a baby in idol years.”

“He’s nineteen. That’s not a baby.”

“To me he is! He still calls his mom every night. Last week he cried because he missed his dog.” Jiwoon squeezed Junwon’s hand. “He’s like a little brother. There’s nothing to be jealous about.”

Junwon knew Jiwoon was right. Logically, he knew. But the image of Heeju’s arms wrapped around Jiwoon’s waist, his chin on Jiwoon’s shoulder, kept replaying in his mind like a bad commercial he couldn’t skip.

“Still don’t like it,” he muttered.

“I can tell.” Jiwoon was definitely laughing at him now. “Big, tough Ahn Junwon, jealous of a teenager.”

“I’m not—” Junwon stopped at a red light and finally turned to look at his boyfriend. “You’re enjoying this.”

“A little bit,” Jiwoon admitted, grinning. “You’re cute when you’re sulky.”

“I’m not sulky.”

“You’re extremely sulky. Look at you, you’re pouting.”

“I don’t pout.”

“You’re literally pouting right now.”

Junwon opened his mouth to argue, then caught his reflection in the rearview mirror. He was, in fact, pouting. He cleared his throat and focused back on the road as the light turned green.

Jiwoon’s thumb rubbed circles on the back of Junwon’s hand. “Hyung, you know you’re the only one I love, right? Heeju is sweet, but he’s just a dongsaeng. You’re…” He trailed off, and Junwon glanced over to see him looking out the window, ears going pink. “You’re you.”

That should have been enough. That should have made everything okay. But Junwon couldn’t shake the feeling, the irrational, possessive feeling that he needed people to know Jiwoon was his. That Heeju and anyone else who thought they could just casually touch him needed to understand there were boundaries.

They made it back to Junwon’s apartment—Jiwoon had been staying over more often lately, keeping clothes and toiletries there—and the silence during the elevator ride up was thick with unspoken tension. Jiwoon kept shooting him looks, probably trying to gauge just how sulky he was actually being.

Once inside, Jiwoon toed off his shoes and immediately headed for the bathroom. “I need to shower, I’m disgusting from practice—”

“Jiwoon-ah.”

Something in Junwon’s voice made Jiwoon pause, hand on the bathroom door. He turned, head tilted in question. “Yeah?”

Junwon crossed the distance between them, and he knew his expression was probably intense because Jiwoon’s eyes widened slightly. “Hyung?”

“I don’t like other people touching you like that,” Junwon said, and his voice came out lower than he intended. “I don’t care if he’s nineteen or ninety, I don’t like it.”

“Hyung, we’ve talked about this—”

“I know it’s irrational. I know you love me. I know all of that.” Junwon’s hands found Jiwoon’s waist, pulling him closer. “But I still hate it.”

Jiwoon looked up at him—Junwon loved that he had to look up, loved the height difference between them—and bit his lip. “What do you want me to do? I can’t just push him away, he’s my member. We have to work together.”

“Tell him to stop hanging all over you.”

“He’s just being friendly—”

“Then I need…” Junwon paused, not sure how to articulate the possessive, territorial thing clawing at his chest. “I need to know you’re mine.”

“I am yours,” Jiwoon said softly. “You know I am.”

“Then prove it.”

Jiwoon’s eyebrows rose. “Prove it? How?”

They stared at each other for a long moment. Junwon could see Jiwoon thinking, could practically hear the gears turning in his head. Then Jiwoon let out a long breath and reached up to cup Junwon’s face.

“Okay,” he said. “You’re being ridiculous, but okay. For today, I’ll let you do whatever you want with me.”

Junwon’s breath caught. “Whatever I want?”

“Within reason,” Jiwoon added quickly, but there was a flush creeping up his neck. “But yes. Whatever you need to stop sulking like a jealous boyfriend.”

“I’m not—” Junwon stopped himself. “Fine. I’m a jealous boyfriend. Happy?”

“Ecstatic.” Jiwoon’s smile was teasing, but there was something else in his eyes too. Nervousness? Anticipation? “So what do you want?”

Junwon’s mind went to several places at once, but one thought kept rising to the surface. The image of Heeju’s arms around Jiwoon’s waist. The casual touches, the skinship that everyone would see and think was just normal idol behavior.

“I want to mark you,” Junwon said.

Jiwoon blinked. “Mark me?”

“So when that kid tries to hang all over you tomorrow, he’ll see that you’re taken.” Junwon’s hands tightened on Jiwoon’s waist. “So everyone will see.”

Understanding dawned in Jiwoon’s eyes, followed by that flush spreading to his cheeks. “You mean… hickeys?”

“Unless you have a better idea.”

“Hyung, I have practice tomorrow, I can’t—” But Jiwoon cut himself off, remembering his promise. His teeth worried at his lower lip. “Where exactly were you planning to…?”

“Where everyone can see,” Junwon said. “Your neck. Your collarbones.” He leaned in close, lips brushing the shell of Jiwoon’s ear. “Everywhere that kid likes to put his chin when he’s hugging you.”

Jiwoon shivered, and Junwon felt a surge of satisfaction. “That’s… you’re being possessive.”

“You said whatever I want.”

“I did say that,” Jiwoon admitted, voice coming out breathy. “But hyung, makeup artists are going to kill me.”

“Let them.” Junwon pulled back just enough to look Jiwoon in the eyes. “Unless you want to take it back?”

For a moment, Junwon thought Jiwoon might actually do it. But then Jiwoon’s expression shifted into something almost challenging, a glint appearing in his eyes that Junwon recognized as his competitive streak showing through.

“No,” Jiwoon said. “I said whatever you want, and I meant it.” He tilted his chin up slightly. “Do your worst, Ahn Junwon.”

Something hot and possessive surged through Junwon’s chest. “You’re going to regret saying that.”

“Maybe.” Jiwoon’s hands slid up to rest on Junwon’s shoulders. “Or maybe I want to see just how jealous you really are.”

That was all the permission Junwon needed. He walked Jiwoon backward until his back hit the wall beside the bathroom door, and Jiwoon let out a soft “oh” of surprise. Junwon braced one hand on the wall beside Jiwoon’s head, the other still firmly on his waist.

“Last chance to back out,” Junwon murmured.

“I’m not backing out.” Jiwoon’s voice was steady despite the rapid rise and fall of his chest. “I want you to stop sulking. So… do what you need to do.”

Junwon leaned in, pressing his lips to the junction where Jiwoon’s neck met his shoulder. He felt Jiwoon’s intake of breath, felt the way his fingers tightened on Junwon’s shoulders. Starting gently, Junwon kissed along the column of Jiwoon’s throat, relearning the places that made him gasp, that made his head tilt back to give better access.

“Hyung,” Jiwoon breathed, and the sound went straight through Junwon.

“Too much?” Junwon asked against his skin.

“No, just… don’t tease.”

Junwon huffed a laugh. “Impatient?”

“You’re the one who wanted this,” Jiwoon pointed out, but his voice was already going hazy. “So stop—ah!”

Junwon had found the spot just below Jiwoon’s ear and sucked, hard enough to leave a mark but careful not to hurt. Jiwoon’s hands flew up to tangle in Junwon’s hair, and the small sound he made was extremely gratifying.

“There,” Junwon murmured, pulling back to admire the reddening mark. “That’s one.”

Jiwoon’s eyes were already slightly unfocused. “One?”

“You think I’m stopping at one?” Junwon traced his thumb over the mark possessively. “I’m making sure that tomorrow, when you’re at practice, every single person knows you’re taken.”

“That’s…” Jiwoon swallowed hard. “That’s going to be a lot of marks.”

“Yes,” Junwon agreed, and moved to the other side of Jiwoon’s neck.

This time he took his time, kissing and nipping before sucking another mark into existence. Jiwoon’s breathing was getting progressively more uneven, his fingers tightening and loosening in Junwon’s hair in a rhythm that suggested he was fighting between pulling him closer and pushing him away.

“You’re insane,” Jiwoon managed to say, voice rough. “Completely insane.”

“You’re the one who offered,” Junwon reminded him, moving lower to the side of his throat. “Could have just told that kid to back off.”

“He’s—ah—he’s just a kid, hyung, he doesn’t mean—” Jiwoon’s protest dissolved into a gasp as Junwon found a particularly sensitive spot.

“Don’t care,” Junwon said against his skin. “Mine.”

“Possessive,” Jiwoon accused, but there was no heat in it.

“You like it.”

“I—maybe—shut up.”

Junwon smiled against Jiwoon’s neck and continued his work. He was methodical about it, spacing the marks out, making sure they’d be visible even with Jiwoon’s usual style of clothes. Some would peek out from a t-shirt collar. Some would definitely show if Jiwoon wore anything with a lower neckline.

By the time Junwon had marked both sides of his neck thoroughly, Jiwoon was practically melting against the wall, his earlier bravado completely gone. His cheeks were flushed, his lips parted as he tried to catch his breath, and his eyes had that dazed quality that made Junwon want to do extremely inadvisable things.

“Hyung,” Jiwoon said, voice wrecked. “How many is that?”

“Not enough,” Junwon said, and tugged at the collar of Jiwoon’s practice shirt. “This needs to come off.”

“We’re still in the hallway,” Jiwoon pointed out weakly.

“We live alone. Who’s going to see?”

“That’s not—that’s not the point—” But Jiwoon’s protests were half-hearted at best, and he didn’t stop Junwon from pulling the shirt up and over his head.

The sight of Jiwoon, shirtless and marked up, hair mussed from Junwon’s hands, back against the wall—it was almost too much. Junwon had to take a second to just breathe and remember that this was about making a point, not about losing control entirely.

“You okay?” Jiwoon asked, and despite everything, there was concern in his voice.

“Fine,” Junwon managed. “Just admiring my work.”

Jiwoon glanced down at himself and made a choked sound. “Oh my god, hyung, how am I supposed to explain this?”

“You don’t,” Junwon said simply. “Let them wonder.”

“The managers are going to have a fit.”

“Not my problem.” Junwon leaned in again, this time focusing on Jiwoon’s collarbones. “You said whatever I want, remember?”

“I’m starting to regret that,” Jiwoon said, but his hands were back in Junwon’s hair, not pushing him away.

“Liar,” Junwon murmured, and set to work on the collarbones.

These marks he made even more deliberately, spacing them out like a necklace of sorts. Every time Jiwoon moved, every time he breathed, they’d shift and catch the light and remind him—remind everyone—that someone had been there, that someone had claimed this particular patch of skin.

“This is crazy,” Jiwoon kept muttering, but his head was tilted back, giving Junwon all the access he wanted. “You’re crazy. We’re both crazy.”

“Probably,” Junwon agreed, pressing a kiss to the hollow of Jiwoon’s throat before sucking another mark just above it. “But you promised.”

“I did, didn’t I?” Jiwoon’s laugh was breathless.

“Too late now.”

Junwon worked his way across one collarbone, then the other, until Jiwoon was trembling slightly, hands gripping Junwon’s shoulders for support. The marks were blooming beautifully, various shades of red and pink that would definitely darken by tomorrow.

“Okay,” Jiwoon said finally, voice shaky. “Okay, that’s—hyung, that’s probably enough—”

“Not quite done yet,” Junwon said, eyeing the tops of Jiwoon’s shoulders.

“Where else could you possibly—oh no. No. Hyung, those will show even with a t-shirt!”

“That’s the idea.”

“You’re impossible!” But Jiwoon didn’t actually move away, just stood there looking flustered and marked up and perfect.

Junwon added a few more marks to the tops of Jiwoon’s shoulders, and by then Jiwoon had given up protesting entirely, just making small sounds whenever Junwon found a sensitive spot. When Junwon finally pulled back to assess his handiwork, he felt deeply satisfied.

Jiwoon looked thoroughly marked, thoroughly claimed. His neck was decorated with blooming hickeys, his collarbones practically painted with them, and the tops of his shoulders bore a few more for good measure. There was no way anyone would miss them. No way anyone could see Jiwoon tomorrow and not know that someone—that Junwon—had been there.

“Can I see?” Jiwoon asked quietly.

Junwon stepped back, and Jiwoon pushed off from the wall on slightly unsteady legs. He made his way to the bathroom and flicked on the light, and Junwon followed, leaning against the doorframe to watch his reaction.

Jiwoon stared at himself in the mirror for a long moment, turning his head this way and that to see the full extent of the marks. His expression was unreadable.

“So,” Junwon said, suddenly feeling a bit uncertain. “What do you think?”

Jiwoon was quiet for another beat. Then he turned to look at Junwon, and there was something in his eyes—heat and exasperation and affection all mixed together.

“I think,” Jiwoon said slowly, “that you’re absolutely ridiculous. I think the makeup artists are going to murder me. I think I’m going to have to wear turtlenecks in the middle of spring.” He paused. “And I think I’m kind of into it.”

Junwon blinked. “Yeah?”

“Yeah.” Jiwoon touched one of the marks on his collarbone, and a small smile played at his lips. “It’s possessive and territorial and completely over the top.” He looked back at Junwon. “Very you when you’re jealous.”

“Sorry,” Junwon said, not feeling particularly sorry.

“No, you’re not.” Jiwoon crossed back over to him.

“Exactly,” Junwon said with satisfaction.

“You’re lucky I love you,” Jiwoon said, but he was smiling. “Insane, jealous boyfriend and all.”

“I love you too,” Junwon said, pulling him close. “Clingy bandmates and all.”

“He really is just a kid, you know.”

“I know.” Junwon pressed a kiss to Jiwoon’s forehead. “Doesn’t mean I have to like it.”

“Fair enough.” Jiwoon rested his head against Junwon’s chest. “But maybe next time, just tell me you’re feeling jealous instead of going full territorial vampire?”

“Where’s the fun in that?”

Jiwoon laughed and swatted his chest. “I’m taking a shower now. These are going to hurt tomorrow, you know.”

“Want me to kiss them better?”

“You’re the one who made them in the first place!”

“So is that a yes or—”

Jiwoon pushed him out of the bathroom with another laugh, but Junwon caught his wrist before he could close the door.

“Hey,” Junwon said, suddenly serious. “You know I trust you, right? This was just… me being stupid.”

Jiwoon’s expression softened. “I know, hyung. And honestly? It’s kind of nice. Knowing you care enough to get jealous.”

“Even when I go overboard?”

“Especially then.” Jiwoon squeezed his hand. “Now let me shower before these start to ache.”

Junwon let him go and wandered to the kitchen to get some water, feeling significantly better than he had at the practice room.

 

Junwon woke to Jiwoon staring at himself in the mirror with a look of dawning horror.

“Oh my god,” Jiwoon said flatly. “Oh my god, hyung, they’re purple.”

“Morning to you too,” Junwon mumbled, stretching.

“Don’t ‘morning’ me! Look at this!” Jiwoon gestured wildly at his reflection. “I look like I lost a fight with an octopus!”

Junwon got up and came to stand behind him, examining the marks in the mirror. They had indeed darkened overnight, blooming into deep purples and reds that stood out starkly against Jiwoon’s skin. They were… very visible. Very obvious. Very much exactly what Junwon had intended.

“You look good,” Junwon said, unable to keep the satisfaction out of his voice.

“I look like I got mauled!”

“Same thing.”

Jiwoon turned to glare at him, but there was no real anger in it. “I have to be at the company in an hour. How am I supposed to hide these?”

“You’re not,” Junwon said simply, wrapping his arms around Jiwoon’s waist from behind. “That was the whole point.”

“You’re enjoying this way too much.”

“Maybe.” Junwon pressed a kiss to one of the marks on Jiwoon’s shoulder, and Jiwoon shivered. “But you agreed to it.”

“Past me was an idiot,” Jiwoon muttered, but he was leaning back into Junwon’s embrace. “Present me has to deal with the consequences.”

“Want me to come with you? Provide moral support?”

“Absolutely not. You’ll just stand there looking smug while I get lectured by our manager.” But Jiwoon turned in his arms, reaching up to cup Junwon’s face. “But thank you for the offer. You ridiculous, possessive, jealous man.”

“You love me.”

“Unfortunately, I really do.” Jiwoon kissed him, soft and sweet and morning-warm.

Later, after Jiwoon had left for the company in a light jacket that did absolutely nothing to hide the marks on his neck, Junwon got a series of texts.

Jiwoon 💕: HYUNG

Junwon set his phone down with a grin. He probably should feel guilty. He probably should apologize for going overboard.

But seeing those texts, knowing that everyone at that company now knew exactly who Jiwoon belonged to?

Yeah. He didn’t feel guilty at all.

Not even a little bit.
