Kirishima gets sleep paralysis and bad dreams on the regular, but instead of telling anyone he just gets himself a Bakugou body pillow which he sleeps huddled with every single night. Ever since he does, the dreams have become better, more bearable.
One day when Bakugou comes to his room to study, Kirishima forgets to hide the pillow and the blonde is stunned to see the hideous contraption with a distastefully printed reboot version of his face on it.
"Is this some kind of pervert thing you got going on?"
"What? No!" Kirishima shakes his head and hands in tandem to emphasize how wrong Bakugou was. "It's for my bad dreams."
Bakugou just stopped and looked at him curiously. "What do you mean?"
"I mean I've been having bad dreams and also sleep paralysis since middle school. It doesn't happen as often anymore, but when it does it's quite bad. I can hardly fall back asleep once I wake up from them and it's just super scary."
"Ok, and how does that play into the fact that you have a pillow with my face on it?"
Kirishima sighs, embracing the fact that he's got no other choice but to reveal the embarrassing truth in its entirety.
"I have it because… it makes me feel safe. You… make me feel safe. I–Honestly, I tried everything else and this was the only thing that worked. I trust you and I do believe you are so strong that you can protect anyone from harm at any given time, so...I guess that's what makes me feel safe when I sleep with it. " Kirishima has become sheepish, his voice barely a whisper.
"You're such a dumbass." Bakugou huffs and walks the couple of steps between him and Kirishima to pull the giant baby into a hug. "Why didn't you tell me you had issues sleeping? I am literally next door." He gently brushes Kirishima's back up and down, while the man's face is buried in his neck, the warm breath making Bakugou’s skin moist.
"I didn't think about it. I didn't think it was an option, really." Kirishima lets out a soft laugh, the self deprecating kind Bakugou hated so much. "I thought you'd laugh at me for sure and just kick me out if I showed up in the middle of the night knocking at your door because I had a ‘bad dream’."
"I would never laugh at you for that." Bakugou can feel the hold tightening around his waist, a warm chest squeezing closer against him. It was true. If there was someone who knew what night terrors felt like it was him. After the ordeal with the capture he has never been the same, he barely had a full night's sleep without waking up in a sweat, remembering the panic he felt when it all happened. "You saved me that time so I can do this much for you."
Kirishima pulls back to look at Bakugou with wide and wet eyes, half in acknowledgment and half in disbelief. "Really? You would? I mean… you don't have to. It's quite a lot to ask to be fair…"
"It's fine. I can sleep here. And if I get sick of you I can always bring my own bed and sleep on the other side of the room ." Bakugou punches Kirishima's shoulder good naturedly, helping his friend regain his composure and cheer up. "I'll go get my stuff and we can continue with math."
Kirishima stares at Bakugou’s retreating back as he leaves for his room to actually pick up his stuff for the sleepover. He feels like he’s living a dream, a good one the first time in a while.
