Izuku wakes up hot—too hot. There’s a thin layer of sweat along his neck and forehead, and he can’t remember what he’d been dreaming about other than the fact that he knows it was nothing good.
And, for a while, he just lays there. Tries to remember the dream even though he doesn’t really want to.
Then,
“Still have them huh.” Katsuki’s voice comes from the other side of the room, and Izuku startles.
“Kacchan? You’re still awake?”
“Oi, answer the question.”
“Oh, sorry… still have what?”
“The nightmares.”
“Oh…” The room goes quiet again as Izuku thinks about how to answer.
“Yes,” he says after a moment. “Sometimes.” He doesn’t mention the fact that they’re usually about Kacchan, even though he’s pretty sure Kacchan already knows. “It’s not a huge deal, though,” he quickly adds, when he hears Katsuki start moving around in his bed, unsettled. “I mean– they’re just dreams, right? And I still get plenty of sleep. They say it’s when you actually go to sleep that matters the most, and I always go to bed before eleven, so I’m sure it’s fine if I get less than eight hours sometimes.”
More rustling comes from Katsuki’s side of the room, and Izuku taps his fingers together.
“Did you know they’ve done sleep studies on–”
“Izuku–”
“Sorry.”
“Stop apologizing and get over here.”
“What?” Izuku turns his head toward Katsuki’s bed but can’t see anything.
“I said get over here, nerd. I don’t have all night.”
“Oh, okay.” Izuku says, quickly scrambling off his mattress and into the dark. He trips over the box of All Might cards he left out earlier that Kacchan told him to put away but he didn’t, before settling in bed next to Kacchan.
Wait, why did he just get in bed next to Kacchan?
Distressed, he stares up at the ceiling, shoulder to shoulder with Katsuki who’s just laying there in silence.
“So, what did you do today, Kacchan?”
“Jesus Christ.”
“What? I’m trying to make conversation.”
“It’s fuck-o'clock in the morning, you think I dragged you over here to talk?”
“No probably not but–”
“Shut up,” Kacchan tells him, and he does, but only because he’s suddenly being pulled into a hug that consists of himself and Kacchan’s big muscly arms.
Wow.
Is he supposed to sleep like this? How’s he supposed to sleep if he’s thinking about Kacchan’s big muscly arms?
And, as if he can read Izuku's mind, Katsuki huffs, “Go- to- sleep.” Then buries his face in Izuku’s hair and takes one of those big sleepy breaths that Izuku rarely hears because he goes to bed at eleven.
And then Izuku does go to sleep.
He doesn’t remember when it happens, doesn’t remember if he has any more nightmares. But when he wakes up well-rested for the first time in weeks, he knows who he has to thank for it.
“Don’t get used to this,” Kacchan mumbles into his shoulder.
“Too late, I’m pushing our beds together.”
