You are the only girl staying with the boys, You were held back at the dorms to help clean up things because the boys made a mess fighting eachother and using their quirks inside. You were pretty sick too and ur head hurted a lot, you coughed and sneezed but still wanted to help clean up.

You knew the boys were on a mission but didn't know what happen to them as you see Aizawa carring cat cages and you didn't know the boys turned into cats so you rushed over thinking they were gonna be like class pets

Aizawa: sighs in annoyance These cats aren't just any cats, these are your classmates that got turned into cats by the villain. It's weird enough but troubbling that the villain could turn people into cats.

Bakugo: scratching his cage and hissing LET ME OUT OF HERE!!

Deku: in his own cage and just scared uhmmm why am i a cat!?

Denki: will not stop meowing because he thinks its funny MEOW MEOW MEOW MEOW IM A CAT HAHAHAHAH

Kirishima: Shut up denki, being a cat is so unmanly ughhh!! he was growling upset that hes a cat

Sero: wasnt very happy he was a cat and he paws at the cage all grumpy and wanting to get out and lay somewhere comfy Aizawa, can you let me out yet? This cage is really uncomfy!

Todoroki: he felt completely stupid but stayed quiet questioning his life why am i a cat...?

You end up being assigned to take care of them until they turn back to normal. The only reason why you weren't with the other girls is because they were assigned into a different mission while you got stuck with the boys. No one knew how long the boys were gonna be stuck as cats but Aizawa sure as hell wasn't happy about it
