Chapter Text
Ga On kisses Yohan’s infuriatingly hot smirk right off his face. Yohan doesn't expect it at all and Ga On takes some satisfaction in taking this seemingly know it all man by surprise. Until he starts thinking about how consensual this makes it.
He pulls away quickly, now furious with himself as he mostly is when he reacts too quickly to Yohan. They have their own little games that they play with each other but there’s the bigger games too, the ones that are part of Yohan’s grand plan. It’s unspoken that they don’t mix the two but Ga On had started this argument about work and he’d ended it with a move on their personal games.
Yohan stares at him blankly for a few seconds while Ga On contemplates the merits of a resignation over a transfer. Suddenly, those carefully managed eyes darken. Ga On has never seen that expression in Yohan’s eyes before, it's new but still unbearably hot. He takes a step forward and Ga On takes a weak one back. Two more and he's against the wall. Ga On blinks up owlishly and Yohan smirks like the insufferable bastard he is. He holds Ga On's face in place and leans into kiss him eyes hooded but open.
Ga On's heart completely stops, all his limbs going numb as if they belong to someone else Yohan’s lips press in and Ga On’s traitorous body reacts before he can process. His awareness returns in snatches and it’s not helpful at all because the only thing he is aware of is that Yohan is kissing him. On the mouth. Really kissing him. Like Ga On's been imagining since he backed him into the shelf in his office and caressed him from collarbone to collarbone through his shirt.
Ga On closes his eyes first and wraps his arms around strong shoulders, drawing Yohan in. Yohan backs him further into the wall holding his waist and kisses him with his tongue. His abdomen is liquid hot and his veins are about to burst from all the blood rushing through him. Every point of contact with Yohan burns beyond bliss and Ga On wants so much more. The kiss turns hungry quickly and both men seek friction with their hips, pressing into each other tightly.
They part for breath and Ga On wants to seek him out but just looking at Yohan is so overwhelming. Ga On sneaks his hands into the front of his robes and shoves them down. He looks away from Yohan’s face and takes in his defined chest and the tanned glistening skin.
He tugs lower until he has to pull on the belt to get the robe completely off. It falls to the floor and Ga On has clear sight of him from chest to hip bones. He's entirely hairless all the way to his v line. Ga On touches his chest and slides his hands down - feasting or appreciating he’s not sure - all the way to his low waistband. He looks up at Yohan's face again, not quite sure where to go from here but wanting very badly to go somewhere. Yohan seems to have been watching him this entire time in some kind of stupor.
There's a lot they haven't resolved about today's case. Ga On has many questions and he's still not quite sure what kind of man Yohan is. Maybe this was his intention all along but no... Yohan had brought him in with minimal resistance because he looked like a ghost of his past. Ga On certainly didn't want to play brother with Yohan. He didn't have siblings but he's pretty sure this isn't the kind of thing they get up to.
"I never expected you to be the kind to watch while someone else does the work." Ga On says because he thinks he should say something before the silence becomes awkward and he can think a little straighter. Thinking straight is of course out of the question when it comes to Yohan
"You're very mouthy," Yohan says low and dangerous. Ga On feels it in the base of his spine. "What if we put that mouth to better use?"
Ga On maintains defiant eye contact and he sinks to his knees. Yohan watches him caught between amusement and shock. Ga On mouths at his growing erection through the silk trousers. He pulls them down and his suspicions that Yohan definitely waxes and definitely doesn't wear underwear are confirmed. He mouths at the sensitive head, looking determinedly at his Chief. His face slightly raised in a, “Is this enough better use for you?” type of way.
Yohan’s returning gaze is hot and intense. He watches Ga On, his face hardly showing any sign of a man with his hard cock in someone's mouth. He looks more like an amused spectator watching a match of a team he only supports when his favourite isn't playing. Ga On is definitely insulted and unhelpfully more aroused and dedicates himself to his new task. Reason be damned, he's going to make this impossible man cum with just his mouth.
Gaon starts bobbing his head slowly, taking the heavy cock in half way in and out slowly. He makes sure to keep eye contact. The taste of precum sours his tongue and he swallows him up in earnest, gagging slightly after not having done this in a while. He hollows out his cheeks and Yohan finally cracks just a little, grabbing Ga On by the hair.
Ga On pulls his mouth off, staring at Yohan until he lets his grip on Ga On’s hair go finger by finger. Ga On immediately takes in his length again eagerly. A tremor starts in Yohan's legs, his hips start to shake with the effort of not thrusting into Ga On's mouth. They keep this game going and Ga On can see the moment when Yohan is about to come and pulls away completely. Yohan gasps at the loss of contact.
Ga On sits on his heels keeping his eyes trained on Yohan's dark intense eyes. He doesn't ask for Ga On to finish him off like Ga On wants. This is somehow still a game and Yohan’s not going to lose either. He maintains the eye contact and starts fucking into his own hand.
Ga On is glued to the spot. Watching as Yohan doesn't give up even an inch of control in his face as he brings himself off with precise flicks of his wrists, tugs and squeezes. His muscles tense and Ga On is ensnared by how perfect the sight of him is and then he comes all over Ga On's face and neck.
Ga On kind of hates himself for enjoying it and maybe a bit too much. Yohan's tight body relaxes a fraction and he pulls his silk pants up again. Ga On isn't entirely sure what's happened, he was sucking on Kang Yohan and then he didn't let him cum. Then he watched Kang Yohan finish himself off. He'd put on a show and Ga On had come from it without even touching himself like an adolescent.
He's starting to question his life choices when Kang Yohan crouches down and places one hand on his shoulder and starts wiping the cum off of Ga On's face. Ga On stops his hand and Yohan cocks his head slightly in question. Ga On takes two fingers, wipes it against the slightly milky coloured fluid on his face and sucks on them, looking Yohan right in the eyes still. Yohan's mouth actually falls open and his darkened expression somehow turns darker, eyes taking in all the light.
Ga On stands and tries to hide the fact that he's cum in his pants. He turns and leaves with a self satisfied smirk. He’s not quite sure what he’s feeling but that’s a problem for a Ga On who either has to forget everything tomorrow or resign.
---
It feels like the universe itself is trying to get in between Kang Yohan and Kim Ga On. Ga On knows he was sent to Yohan as a spy by one of the only two people he trusted most. What he discovered was that Kang Yohan's methods were unorthodox but they were giving results. He’d come to terms with it to an extent, he’d justified it and it had made sense.
But now Su Hyeon looks at him like he's a monster. Ga On can't get over the way she'd looked at him that night, it's burned into his retinas. And now nothing makes sense anymore. He’s a criminal, Yohan’s made him into a criminal, or he has. Yohan holds him and tells him to part ways with her, that she just doesn't understand. He holds onto Ga On.
Ga On's mind is a mess. A mess. Everything is just a mess. Su Hyeon is his childhood friend, someone who would be there forever. What is Kang Yohan but a fleeting dream? How could Ga On choose him over his childhood love, how could he even consider it? He just doesn't want her away, doesn't want her to look at him like he's a walking tragedy already.
He walks away from Yohan.
He comes back of his own accord. Su Hyeon is no longer angry but she's still looking into Yohan. Ga On knows this isn't a fight they can win without Yohan.
Cooled down from the fear he'd had of losing half of the closest thing he has to family, he can't really face Yohan. He goes back in confrontational. This is work, he tells himself. I can't mix work with pleasure. What was I thinking cooking for this man, helping raise his niece with him, pretending I was part of his family. He's my boss. He's not a good person.
He feels sick when he leaves the office.
Su Hyeon is home when he gets there and he musters up the happy greeting. She's warmed up food for them and is halfway through a beer.
"You look tired." She notes.
"The situation is really bad,” he replies then adds, “ and the people who should be doing something are the reason for it. You'd do better investigating those bastards than Yohan."
"I will but I've got a good lead on this Yohan case."
They sit in silence, it's awful.
Ga On shouldn't have the time right now to be thinking about his relationships but he can't not. Yohan looked différent in his office, still beautiful and imposing but his complexion had been all wrong and he'd been sweating in an air conditioned office. Is he sick, Ga On wonders and reminds himself it's not his place anymore to wonder if he’s doing well, sleeping well, eating well or any of that.
"Are you going to move back there if Yohan is not a bad person?"
The question catches him off guard. He presses his hands further into his hoodie pockets and looks up at the satellite addled sky. Su Hyeon isn't looking at him, like always when they have something important to discuss
His first answer is he's not sure if he'll be welcomed back. So he doesn't answer at all.
"I hope he's not a bad person for your sake." Su Hyeon surprises him by saying. Sometimes he wonders just how much she knows.
"He's not. I know he's not. He's a bit extreme but he'd never do what you think he did."
Su Hyeon finishes both her beer can and his. "Why did you run away from him then? If you think he's a good person."
Ga On swallows. “Because when he asked me to abandon you, I wanted to do it. Because if you hadn't caught me that night I wouldn't have stopped. Because I hurt for him and I want to understand him and I want to be by his side as more than just a colleague. Because I was afraid of the person I was willing to become if he asked me to. Because if he leaves me first, I just might die” He can’t say any of those of course so like the coward he is, he just stays quiet.
"I love you, Ga On. I love you so much I want to protect you from every bad thing in this world. Even shave off the thorns from your roses." She says and sighs aloud. "If Yohan is bad for you I want to protect you from him, even if it means the world will be damned for it. You've been hurt so much and I can't bear seeing you in pain anymore."
The guilt crushes his chest.
"I cared more about protecting your future than doing my job. The autopsy and cctv proved it was a suicide but I didn't know that at the time. But still I hid the evidence. Do you understand? I thought you were an accomplice to murder or even a murderer and I wiped your fingerprints off a crime scene."
"Soo Hyun-ah."
"I became a cop to protect you but I also took an oath. I broke it because of you. Because I cared too much about you."
Ga On has never showed the worst parts of himself to Soo Hyun. He never wanted her to find out that there were parts of him that were still that boy who'd taken a knife to that court house, the rebel that got into fights without any intention of coming out of them.
Ga On has many feelings and despite that fact that he appears to be the most emotionally well adjusted among the Kang's household, he often struggles between them. What he's feeling and what he should be feeling.
All that he should be feeling right now is, sadness and guilt but then he feels just a little angry too. People like Yohan wouldn't have to exist if people like Minister Cha and the Professor and Soo Hyun and him did their jobs correctly. What importance did the law really have when it turned away from justice?
Another part of him is thinking of Yohan and empathising. "Is this what it's like?" he wonders aloud but still quiet.
"I don't know what to say to you," Ga On says into the quiet night. "Su Hyeon-ah, I'm not who you want me to be or who professor wants me to be. I want to say he's corrupting me that he's using the weakest and worst parts of myself to further his own plan but it's ridiculous isn't it?
I went to Yohan’s side on my own. The law is broken and the people in power even more so. Yohan can do something about that and I want to help him, learn from him, and protect innocent people." Ga On takes Su Hyeon's hand. "I'm confident that whatever you find tomorrow won't change my mind about that. I shouldn't ask you for anything after what you did but I want you to be on our side and I want you to stop trying to take on all my burdens and sheltering me. I want you to stand by my side and I want us to help each other as friends and colleagues."
Su Hyeon turns to him. She's still teary faced. She puts her other hand over his and pushes his hand away. She doesn't say a word as she leaves. Ga On cries himself to sleep but he knows he made the right choice.
The next day Judge Oh starts working with them and it feels like a glimmer of hope.
------
Tomorrow is the day of their first big step against the foundation and the government. Ga On goes home with Yohan for 'safety reasons' but really he misses Elijah and Yohan just a little bit.
Elijah's cold to him which he expected and he doesn't attempt to thaw her out too much. He makes sure she eats dinner and leaves her to her studies. The unknown variable is Yohan. Yohan eats the food Ga On cooks for him with Ga On there then he retreats to his study. After an hour Ga On pushes the door to his study open.
He knows their plan for tomorrow is dangerous. They've already taken Han Yeon Soo and K is in an ICU halfway across the world, Lawyer Go, and the chief are the only ones they have left. Ga On hadn't even heard it from Yohan. He'd heard it from an angry Lawyer Go questioning his allegiance.
He sits on Yohan's desk and reaches out to sift through his fringe a little. Yohan looks up from his book and studies Ga In from a second before asking, "What is it now?"
Ga On shrugs and takes his hand back into his lap. "It's okay. Continue, I'm okay."
Yohan's expression is sceptical but he continues reading. Ga On just watches him. It's been almost a week since the incident with Su Hyeon and he'd packed his bags and left. He's missed this complicated face so much it's unreal. They sit for an hour before Yohan says he's going to sleep.
"Okay, let's go." Ga On says with enthusiasm.
He follows Yohan and stops at the threshold of his bedroom. He's gotten away with slipping into Yohan's bed from time to time but things were a lot less tense between them.
Yohan goes to the bathroom to clean up. Ga On steps in and shuts the door behind him. He takes off his shirt, then puts it back on. Yohan comes out of the bathroom without his shirt, he hangs the robe on his rack and makes it to the other side of the bed without giving Ga On a clear sight of his back. Ga On turns off the lights once Yohan settles in and slides into the sheets beside him.
He faces the ceiling. The room gets slightly less dim as he adjusts to the dark. The moon filtering through. "Sweet dreams," Ga On says and turns around to fall asleep.
He's too wound up to do much sleeping. The anxiety of what could happen tomorrow coupled with the anxiety of whatever is going on here battle inside him for dominance. Yohan hasn't moved a single inch so he's not asleep either.
Ga On turns and Yohan's dark eyes are open, facing him. Ga On offers him a little smile. "Why did you come back?" Yohan asks, his tone like he's questioning a defendant, measured and giving nothing away
"Did you not want me to?"
"I asked you a question."
"I didn't think I wouldn't come back."
"Then why did you leave?"
"I needed time to think."
"Why can't you think here?"
"Because you're here," Ga On answers honestly.
"What? You can't think when I'm around?” Yohan asks.
"I can. Just not about anything useful." Ga On says and dares to move closer. He's a lot bolder with Yohan than he'd ever been with So Hyeon. He puts his fingers on Yohan's face. "I think about kissing you a lot, about letting you domesticate me among other things."
"Why do you have to say such things so sincerely?"
"Why do you have to pretend you don't like to hear them?" Ga On asks in return, heart in his throat. Because he might be reading Yohan completely wrong.
Yohan kisses him, a lot tenderly than they usually kiss. Ga On melts into it, pressed flush against Yohan. He savours the taste of mint mingled with Yohan. Yohan's crazy if he thought that Ga On could really leave him forever after the way he and his niece have taken up permanent residence in Ga On's chest.
"I'm glad you're back." Yohan says. "I'm glad you're back home."
"I didn't think you'd want me back after the things I said." Ga On’s chock full of tears already, the word home ringing like an alarm in his head.
"After how hard I worked to get you on my side? It's all under the bridge."
Gaon nuzzles into Yohan's neck. "That's a relief." he breathes. He wasn't confident at all that he'd made the right choice following Yohan home and he realises it now. Yohan wraps his arms around Ga On and Ga On places his hands on his abdomen. He knows never to touch Yohan's back when he's shirtless unless it's presented to him.
"Kim Ga On," Yohan says tone slightly scolding.
"Yes chief?"
"I meant it when I said I want to sleep."
Ga On's face gets impossibly warmer. "So do I."
"Doesn't seem like it."
"I'll go deal with it." Ga On says and attempts to disentangle but Yohan has other plans. He flips Ga On onto his back and presses him down to the bed and grinds his own growing erection against Ga On's.
Ga On laughs a little breathlessly. They grind against each other in the dark seeking friction. Yohan kisses down Ga On’s jaw, leading a hot trail to his the base of his neck. Yohan tugs at the hem of the sweatshirt Ga On sleeps in and Ga On helps him get rid of the garment.
Yohan reaches for the lamp and switches on the light. He takes in Ga On in the warm light and brushes his face with the back of his knuckles. Ga On’s not shy about taking in his own eyeful and notices the white square bandage on Yohan’s abdomen. He reaches out for it, “What happened?”
“It’s okay now,” Yohan tells him. Lawyer Go hadn’t mentioned anything about Yohan getting injured as well. Yohan takes his attention away from it by kissing him brainless.
He writhes in place as Yohan plays with his nipples. His breath is already coming out in soft gasps and his cock is uncomfortable under his pants. Yohan leaves open mouthed kisses all the way to his abdomen and peels off the sweats and underwear in a fluid motion. He props Ga On's legs up and descends upon Ga On's cock with determination.
There hasn't been much or any very sexual interaction between them since that day Ga On had burst into his office demanding why he never fills him in on his plans. Ga On had been flushed and confused from that strange dream he'd had where Yohan had castrated that man and worse how turned on he'd been from it. He’d lost sight of why he confronted Yohan to begin with.
They’ve had two or three cryptic conversations alluding to something like stopping. All of which have ended in teeth clashing kisses and hips on hips chasing each other through clothes. There's been nights in this bed where they just sleep and Ga On is content to be spooned from behind. If he really thinks about it, he’s been domesticated already.
There hasn't been anything like this and Ga On had suspected it was another one of their games, waiting for who would cave first.
Unsurprisingly, it's the best blow job Ga On has gotten. He lies there and tries to muffle his moans with the pillow. Yohan stops just to pull the pillow away and prop Ga On up on the headboard so he has an eyeful of Yohan swallow him almost balls deep, his saliva drooling down. His release builds up in a very short time especially with the visual of Yohan with his mouth full of Ga On’s cock. Yohan swallows, with only a slightly dribble down his chin. It's hot white bliss and he arches up into it, biting into his hand not to groan. Yohan doesn't wipe his mouth and moves up Ga On's body. "Unlike someone, I deliver." Yohan tells him.
"I think you liked coming on my face a lot actually."
Yohan takes his chin between his thumb and forefinger. "You always surprise me. I never expected you to be so vulgar with all your properness."
"This is proper," Ga On says and it feels like there's an added layer of meaning. "Coming on each other's faces between two consenting adults is proper."
"You're really something, Kim Ga On."
"Coming from you?"
"Judge heartthrob by day, sexual deviant by night."
"If you didn't have such big windows in your office, I could be a sexual deviant and a judge by day." Ga On tells him and then laughs at the expression on Yohan’s face, "I didn't expect to be a lot less prudish about this than you, but what else can I expect from an old man?"
"Stop with that, I'm hardly forty."
"Of course you aren't," Ga On grins. He uses Yohan's unguardedness to get in a judo move and flip them around. He starts mouthing the skin of Yohan's collarbone and he says, "When you talked about a fierce woman who'd slapped and pulled your hair, I thought of course. He probably has a dungeon too where he could tie up a doe eyed unassuming judge or-” He stops and pushes Yohan’s hair out of his face, lingering just above his lips, “be tied up by a doe eyed unassuming judge."
Yohan tilts his head and raises a brow. He tugs at Yohan's hair and Yohan’s cock reacts. Ga On smiles and asks, "Do you like it when I pull your hair?"
"A dungeon? You imagined I had a sex dungeon?" Yohan asks incredulously avoiding the question.
"Is that a confirmation that you don't?" Ga On asks, "I think İ might be a little disappointed, Chief."
(If Yohan decides he's going to build a sex dungeon then and there that is his business.)
"So you won't tie me up and flog me?"
Yohan actually chokes. And he's half sure Ga On is fucking with him but he looks so sincere about it somehow. Fuck me, Yohan thinks, and thinks that Ga On might like that very much. How did he pick up this gem of a human being? Just when he thinks he's gotten close to fully figuring him out, Ga On pulls down another veil and Yohan's amazed and mesmerised.
"Something can be arranged."
Ga On's eyes actually sparkle. He kisses Yohan and they both give and get just as good. Ga On convinces Yohan into binding his hands over his head and then he gives Yohan a dry hand job, using only his precum for slight lubrication. He kisses Yohan and tells him he did well. Yohan isn't sure what's happening here anymore.
He spoons Ga On to sleep after they've changed and cleaned up again. This time they really do fall asleep.
