as soon as class was over, Katsuki ran to his room, without grabbing any of his stuff

*you grabbed his bag, books and everything he left behind and went to his room. You knocked on the door

"G-go a-away!"

he was sobbing, and hyperventilating

"J-just g-g-go!"

you barged in

"I-i-i-i s-s-said g-go-"

he got up and pretended nothing was happening
