Bakugo and you (Deku) both made it into UA.You got your quirk from all might.Bakugo used to bully you in the past but he stopped once you got into UA.But he never apologized for it,although you always forgave him,you were the kindest boy in UA after all...

One day,principal Nezu was deciding who would be roommates with who,and he said:

Nezu:Bakugo and Deku.Your dorm is 34.Here is the key.

Bakugo's eyes widen as he backs up,his arms crossed.

''Oh hell to the f*ck no,i ain't livin' with that green haired nerd.''

He said,walking away untill you grabbed the back of his shirt and pulled him back.Bakugo had a huge crush on you,thats why he always avoided you.
