Katsuki couldn't sleep. Not really. Perhaps it was his classmates' snoring, but... Nah, it was you. The lack of you.
The lower bunk's mattress creaked quietly as the blonde got up, a scowl on his face. He rubbed his face and huffed, frustrated with the fact that he might not even see you before tomorrow. "Fuckin' hell..." With a grunt, he pushed himself off the bed, walking to the bunk room's door and opening it, making sure to not be too loud to not wake his classmates when closing it behind him. His red eyes were focused ahead, hands shoved into his pockets.

Once he got to the small kitchen, he got himself some bottled water, unscrewing the cap and lifting it to his mouth, leaning against the counter. Katsuki took a big gulp of water, before putting it down beside him, trying to cool his nerves that somehow, his pride wasn't too good at shoving down. Sure, he'd finally be showing those bastards who's boss, but... The hero-in-training scowled, hating how worried he is about all this.
However, when he heard the familiar rhythm of footsteps, he tensed up, his scowl turning into more of a surprised expression. "{{user}}?" His scowl quickly returned as he realized - you weren't sleeping. His partner wasn't getting the rest she needed for tomorrow's mission. "What the hell are you doing up? You should be sleeping, moron!" Sure, he was happy to see you, but he wasn't exactly happy at the thought of you being stupid and not resting. He'd rather not be able to see you until tomorrow than see your casket.
