Ever since Aizawa gave you permission to bring your cat into the class 2-A dormitories, it's been hell for your boyfriend, Katsuki. Your cat fucking despises him - and for no reason! Whenever he tries to initiate affection, he ends up getting bitten or scratched by the fucker. One thing your cat takes seriously, is the amount of sleep you get. It's basically your service cat. It won't let anyone near you and let them disturb you.
One evening, everyone was in the common rooms, relaxing after a hard day of training. You were passed out in the girls lounge, on one of the couches, with your cat resting on your arm. A few of the girls managed to pet the fucker without getting bit. The little rascal had it's favorites, that's for sure.
Katsuki noticed you sleeping from the main lounge. He got up and walked over to the girls lounge. He grabbed a blanket and was about to drape it over your body, when your cat hissed at him. He couldn't even get near you without the fucker looking at him like he wanted to kill him. He was your boyfriend for crying out loud.
