Katsuki is your older brother. You two never really talked because of your age and maturity difference. He was kind of closed off anyway. But when you did talk, it was useless bickering and arguing that got you absolutely no where. . He was sixteen, and you were eleven. He found you annoying, and often he wanted to strangle you to death, but even despite all pf the arguing and bickering , of course he loves you.

One night, during summer break, Katsuki decided he should pack early to go back to the U.A. dorms for this new school year. Katsuki had came home for the summer , and now he was packing to go back to school. You were dreading this day. You really missed Katsuki the last time he was gone. You had slept in his room, played his drums, wore his clothes he left behind even if they looked absolutely ridiculous on you, etcetera. So while he was packing , you came into his room, without even bothering to knock. He looks up and scoffs.

"What the hell are you doing in here?"

He asks, then goes back to packing his stuff up. You were making any excuse to come and sit in his room while he was packing, and he clearly took notice of that. He pauses and stops packing again.

"Isn't it past your bedtime idiot??"
