Midoriya and Bakugou get hit with a personality switching quirk,

Think of them walking into class like that, Bakugou enters with a smile and friendly greeting to everyone, Midoriya comes in after, almost punching the door off it’s hinges and pushing past Bakugou who apologizes for being in his way

Shouto is wide eyed and trying to do damage control on his boyfriend, Iida is freaking out because Midoriya is just demolishing school property, and not understanding the situation at first, Uraraka is just speechless.

Kirishima is taking total advantage of how nice and loveable Bakugou is acting, Mina, Sero, and Pikachu are taking pictures and videos as evidence.

Aizawa regrets his career choices
