Work Text:
On the list of things you likely shouldn't do, sleeping with your childhood friend turned ex-boyfriend turned somewhat co-worker on a weekday night, in a dorm room no less, was probably rather high up the list. The fact that Keito had someone who fit that description was a problem in the first place, really, even more so when that someone was, well... genius idol extraordinaire Rei Sakuma.
Keito knew all this, had run over the facts in his head, and came to the conclusion that this could only lead to more trouble than good, and yet.
And yet, despite all of this and his rational brain sighing in exhaustion, Keito had let Rei in. He had invited him in, even, saw the exhaustion on the older man's face when he ran into him in the kitchen and accepted the excuse that they should rest together.
"You still have trouble sleeping outside of a coffin even now? How incorrigible. Surely you can sleep in a bed after months in the dorm, come here—" Really, what kind of idiotic, nonsensical spiel had gone through his brain earlier?
All that added up lead to here, Rei sharing his bed and the two of them not cuddling, except their limbs were tangled up and somehow Keito had his head on Rei's chest and the strangest thing was that he did not mind. Thank god his roommates were all away; he'd never be able to live it down if anyone found out.
Neither of them was asleep. Rei's eyes were closed, though. Keito's glasses had been set aside, rudely pulled away by his... not-partner, but they were close enough that he could see his features nonetheless. He really was unfairly beautiful, that Sakuma, especially like this, breathing even and expression strangely peaceful. Did he enjoy this? The arm he had around Keito was gentle, carefully placed over his shirt lest he complained about cold skin.
It was strange. They had shared a bed in the past, but never like this. Never so quietly comfortable. Rei had never been like that. Or perhaps, Keito had simply never let him, finding it easier to detach himself when Rei wasn't being so caring. It was too late to find out now, and still, he found himself wondering.
"You've been staring quite intently at me for a while, Hasumi-kun. Do you have any grievances with me, or are you perhaps simply transfixed by my beauty?"
Keito felt his voice as much as he heard it, the low murmur rumbling through the chest underneath his head. He stumbled to find the words to say—of course, Rei would notice, how could he let himself stare so openly?
"Absolutely not. I was just wondering if you had somehow fallen asleep," he managed the spit out. He felt the soundless chuckle that ran through Rei's body, too.
"I am still a creature of the night, after all. But I am comfortable, and I do believe I'm in quite pleasant company."
"You just refuse to change, don't you?" An excuse, to hide the way Rei's word made his heart beat half a second faster. They were simple words, objective words, but an awful longing bloomed in his chest anyway. It was hard to listen to his senses like this, when it felt like they were in a bubble of their own, with no outside eyes and all the space for his feelings to run rampant. He should not...
The hand on his shoulder moved to his head, bringing him just a little closer. "Relax." The touch did the opposite if anything. He felt his body freeze up, even as Rei started playing with his short locks. "I'm not gonna pull anything, and I'll stop if you want me to. So don't worry your pretty little head over it, Kei-kun."
Stop that. Don't do that.
He didn't say that. Rei really would stop if he asked him to, he knew. This wasn't that sort of situation. They weren't those people anymore.
"Must you insist on calling me that?"
He glanced up and saw that red eyes had opened again sometime in the middle of his conflicting thoughts, an amused gaze turned to him. "I think you like it."
"I think you have a terrible habit of trying to presume people's feelings, Sakuma." He made sure his tone was pointed, emphasizing the other's name. Not that it mattered, because Rei could read him any day, the only reaction he got was a slight quirk of the lips.
"Old habits die hard." Then, added in that truly insufferable tone he used when he knew he won an argument, "Besides, I said you can tell me to stop. You didn't."
Damn it.
Therein lied the problem. Keito didn't want any of this to stop. He enjoyed being able to enjoy the other's presence like this, hated how easy it was when no one was looking.
Another soft chuckle left the dark-haired man, before the hand in his hair dropped back to wrap around his shoulders. "Don't stress yourself out, Kei-kun~"
"You're doing this on purpose."
"Am I, Kei-kun?"
"I swear—" Keito finally pushed himself up, sitting up with no resistance from the other's end, and those red eyes were still full of amusement. "I will tell you to leave. Who cares if you can't sleep, it's not my problem, you're not even sleeping here anyway!"
Silence, then: "Kei-kun."
"You are so…!"
A snicker, clearly audible this time, and how long had it been since he last saw Rei Sakuma looking so youthful? "You're still not actually telling me to leave, Kei-kun."
Albeit at the expense of Keito's sanity, it seemed. Honestly, why did he have to be surrounded by people who appeared to be endlessly bemused by his suffering?
Though, it felt much as if they were children playing again, like they were teenagers sneaking kisses in the student council room even when Keito so clearly said this was a terrible idea, like they were kids who thought they were bigger than the world.
It made his expression cloud over.
The hardest part of this was that Rei seemed to have completely accepted the reason why they weren't that anymore. Keito could admit, at least to himself, at this moment where his walls were being thoroughly ignored, that he quite hated that.
He heard Rei sigh, and then he was dragged back down into a hug, cold arms around him and a blanket pulled over their forms. "You have a bad habit of overthinking," he pointed out, annoyingly right. "You're helping me rest, and it does not have to be any more than that."
It was unsatisfying, wasn't it?
This was Rei Sakuma, though, so what else did he expect?
Finally, Keito let it happen. Sure, he'd buy into that excuse. It's not like he hadn't used too many stupid excuses that night, what was one more to the list? He could write it off as a moment of weakness.
As he relaxed in Rei's hold and let his eyes close, he might have felt the other man smile. He told himself it didn't have to mean anything—he didn't even see it, it might have been a figment of his imagination. That was fine, for now.
"Thank you," Rei murmured.
This was fine. He didn't have to figure it all out right this second.
"Good night, Rei."
