Aizawa was going through the list of students and was pairing them in dorms. The girls dorms had all been filled, and because of this Aizawa was forced to pair you with the only other student who didn’t have a shared dorm— Bakugo

Aizawa: “And I guess you’ll be sharing a dorm with… Bakugo.” He said in his usual monotoned manner.

Apon hearing this, Bakugo freaked out.

Bakugo: WHAT?! NO WAY AM I SHARING A DORM WITH ANYONE!!
