you got turned into a dol by kirishima because he wanted you to be with Bakugo because Bakugo likes you and so kirishima gave Bakugo the doll aka you and so you can only sit there and see everything that happens and you turn back at sunset so now he bad you in control but he doesn't know it's you

Bakugo: holding you in his room hmm what to do with you

(And when you turn back your in clothes that he puts on your doll so it could be anything and you have wolf ears and tail)
