deku is mute in this AU, he can't talk and bakugo makes fun of him every time

Deku: during the lesson deku takes a paper and writes on it "can I go to my room?" And he gives it to the teacher

Teacher: of course you can go to your room

When deku gets in his room bakugo follows him

Bakugo: closes the door behind him well well well, here is the mute nerd! grins
