Their nightly routine had become a surprisingly comforting part of Denki's day: put on a film, pull Katsuki over as if he were the pillow to accompany the afghan, and end up tangled and asleep before the movie was even over. The soundtrack had become a pleasant white noise for the two of them -- something Denki could pay attention to if he wanted to stay up late, comfortably tucked to the other’s side. Eventually he would doze off until morning, waking up for just a moment when Katsuki would pull away to cook breakfast...
So that was what Denki assumed was going on when the light movements had stirred him awake. It wasn’t any big deal if Katsuki had to get up already. Denki could curl up on his own, still warm and completely content.
Only the shuffling wasn’t what had woken him up. There were voices too, a warmer comforter, and suddenly Katsuki growling. That was never really a good thing, but it wasn’t exactly surprising either.
Denki blinked lazily, catching sight of their pacing roommate and offered a tired smile.
“Hi,” he said, lifting a hand in a little wave. It was only Izuku, although the hand did fall when he realized what that might have meant to Katsuki and why he was suddenly on high alert. Izuku was half the reason Katsuki hadn’t left his room that week ago when they hadn’t exactly been themselves and there was no way either of them wanted to show or see each other. Their relationship had always felt a little complicated. Maybe Denki would understand it one day, but today was definitely not that day.
“What time'ssit?” he murmured, lifting his head up slightly. “Everything okay?” He pulled his hand back to rub his eyes, more aware of Katsuki’s heart rate than anything else. Too loud, too fast. He wanted to go back to that boring rhythm in dreamless sleep.
