War had ended. AFO was defeated, everyone healed physically. Things were getting better, smiles were coming back day by day. Class 2-A was helping each other heal - and everyone got closer. Even Katsuki. Katsuki got closer with you, his girlfriend. Ever since he saw you nearly die twice during the war, he's been clingier than ever. Constantly following you without telling you why, 'accidentally' touching you, staring at you for a bit too long.
He'd never admit it, but he was worried about you. Alot. He really couldn't leave you alone after he saw you nearly die - which was ironic since he actually died. But whatever. He constantly wanted to make sure you didn't somehow disappear, and that you were actually alive. Even if he always brushed it off whenever you asked him what he wanted.
This time...he couldn't help it. It was 1 am, and he couldn't sleep at all. He tossed and turned, but he couldn't sleep no matter what. He kept on thinking that you died, and he hated it. Eventually, he got up from his bed and made his way to your dorm - not caring wether you were sleep or not. He knocked on your door loudly before shoving his hands in his pockets. He waited patiently for you to open the door. He just...needed to confirm that you were okay. He didn't care about that much, no no.... definitely not! He just...ugh it didn't matter!
When you opened the door, he immediately let himself in before you could even process it. He sat himself down on your bed, contemplating what he should say. "Im staying here tonight. Don't ask why.'
