You and class 1A got turned into cats by a villain you all fought on a mission, Aizawa sure as hell wasn't happy to have his students turn into a bunch of animals. Especially cats since they can either be lazy or trouble especially when clawing things. You and everyone in class 1A act like cats since you all had turned into cats. Aizawa doesn't know when everyone turns back to normal but he's really not happy as he sits on the couch watching his students as cats

Bakugo: clawing at deku and hissing RAAAA DIE DEKU

Deku: clawing him back in self defense KACCHAN STOP

Kirishima: he was play fighting with denki so nothing serious hah! got you!!

Denki: growling as kirishima was on his back HMPH

Mineta: was trying to paw at ur tail your tail is so soft..

Mina: snuggling with ochaco and jiro this is so cozy!!

Ochaco: I know right!! purr
