Summary
“That’s right,” Junseo said indulgently. “All yours, kitty. You’re the one who’s about to knot me, aren’t you?”
Xinlong’s head shot up, ears perked, and he stared wide eyed at Junseo. “I can…?”
“Yes,” Junseo said, grinning at the look of sheer excitement on Xinlong’s face. He was, as always, so wonderfully transparent.
(or, the one where junseo leaves on a business trip and comes home to find xinlong in heat)

Junseo
Sangwonnie, are you awake?
I can’t sleep…The message was read at once. Sangwon was still there in the chat, and his reply was quick and short.
Sangwon

Summary
That’s what it’s been like for the past two weeks; sneaking around, hiding. It’s left Junseo feeling like something that’s been mislaid, slightly out of place. Everything has changed, and yet nothing has changed. He and Sangwon have changed, but they have to pretend they haven’t, that they’re the same as they’ve always been, and it creates a strange sort of dissonance in Junseo’s heart. It makes it hard to tell what’s real and what isn’t, hard to be sure of where they end and where the pretending begins.
(or, after hooking up during paris fashion week, junseo and sangwon never really define their relationship, leaving junseo questioning what exactly he means to sangwon.)

you are my angel, come way from above by TwoBodyProblem

Summary
Junseo's trust in Sangwon seems to be something innate, buried deep in his subconscious. It’s something he does as easily as breathing; when Junseo sleeps, his body remembers to breathe, it remembers Sangwon—and it trusts Sangwon.
(or, during their busy KCON schedule, junseo drifts off in his and sangwon's shared hotel room.)

Tags
Summary
“Long-ah,” Junseo interrupts, and Xinlong’s mouth snaps shut. He stares at Junseo wide eyed, with a look that's half anticipation and half dread. “I… you… say that again.”
Xinlong swallows, Adam’s apple bobbing. “Noo– noona?”

Sometimes when I look down, it’s interesting by TwoBodyProblem

Summary
Junseo can only watch while Sangwon taps away, and then, Sangwon flips his phone and shows Junseo the screen. It’s a Plus Chat post with two photos taken from Sangwon’s POV, looking down at his legs. The exact same view he has right now, sans Junseo on his knees choking on his cock. The caption reads ‘Sometimes when I look down, it’s interesting’

Summary
It’s an intoxicating feeling being the one, the only one, that Junseo is like this with. It comes with a sense of both pride and responsibility. The only person that gets to see Junseo like this, face flushed and shy, but body open and trusting, is him. There’s no high in the world that could compare.
(or, in the midst of their busy schedule, Junseo plans a surprise for Sangwon's birthday.)

Summary
They finish dinner and get in a car to go back to the hotel; like clockwork, like it’s second nature, Sangwon sinks into a seat next to Junseo. His fingers brush Junseo’s thigh as he buckles his seatbelt, and it burns. It all burns. All day, it’s like Sangwon’s been building a fire in the pit of Junseo’s stomach, kindling made up of stolen touches and softly uttered words, promises made but not yet kept.
(or, during their trip to paris, things junseo has tried to kept hidden are finally brought to light, and he finds sangwon on the other side)

Summary
The three-body problem, in astronomy, is the problem of determining the motion of three celestial bodies moving under no influence other than that of their mutual gravitation. No general solution of this problem is possible, as the motion of the bodies quickly becomes chaotic.
(or, Junseo has spent two years pining for his roommate, Geonwoo, thinking that his feelings are one sided. When Geonwoo starts dating Sangwon, he thinks that maybe this will finally allow his heart to get over Geonwoo, but instead he finds himself falling for Sangwon too.)
-
Tags
Summary
“Can I help you?” Geonwoo says, voice low and even, an edge to it that isn’t usually there. Not around Junseo, anyway. The hand that isn’t holding on to Junseo’s wrist is balled tightly into a fist, and he’s fighting every instinct in his body that’s telling him to just knock the man in front of him out. “If you have something to say to my husband, I’m sure you can tell me too.”
(or, someone gets a little too close to Junseo at a company party, and Geonwoo, like any good guard dog, bites)

Summary
Sangwon shivers at the rawness of Junseo’s voice, the vulnerability; it’s dizzying. Is there anything more intimate than this, he wonders, than trusting someone so much you’re willing to let them hurt you— that you want them to hurt you? He supposes this all stems from that, from wanting to trust and be trusted, from a want to be closer to Junseo, so close they might end up one person. Sangwon is curious, he wants to know everything, every single thing about Junseo, every noise he can make, every expression he can pull, wants to know his body and how it works, what places to bite down and where to hold.

Summary
Their eyes meet again, and Jiahao looks pretty like this too, even prettier than he did in Junseo’s head the countless times he imagined him between his legs. Junseo didn’t think he’d ever get to have this, the privilege of unabashed staring, of wanting without the following gut reaction of shame. But he does, because on the 25th of September, the universe gifted him two things; a spot in the debut lineup of ALD1, and later, in the dark of an unfamiliar dorm room, Zhang Jiahao.
(or, the one where jiahao surprises junseo on his birthday.)

Summary
“I don’t understand?” Junseo repeats, now incredibly frustrated himself. “Make me, then.”
A beat. The air between them changes, and Junseo is suddenly very aware of their close proximity, of the rise and fall of Jiahao’s bare chest, his fingers wrapped around his wrist. Junseo wants to pull away, escape it somehow, but Jiahao won’t let him.

Summary
Jiahao smiles back, squeezing his hand. “Together?” He says quietly.
It’s not quite a promise, but something close to it. Something secret, to be tucked between the ribs and held there till either it happens or it doesn’t.
Junseo nods. “Together,” he says.

Summary
“It just… it has to be– it has to be perfect, you know?” Sangwon says.
“What are you talking about?” Junseo asks, though he thinks he knows well enough.
“The killing part,” Sangwon replies. His voice is so quiet now that Junseo has to strain to hear it, even standing this close. “It has to be perfect, it… it has to be irreproachable.”
“Why?”
“To make up for it,” Sangwon says shakily. “To make up for the fact that it’s me.”
