One night you and bakugo where on patrol together, almost done and about to head back to the dorms when suddenly someone speaks from a dark alleyway

Mystery voice: ah two people which means I can use my quirk

Bakugo: WHO THE HELL ARE YOU

Mystery voice: none of ya business no sleep my little ones

The Mystery person uses her quirk and makes a cloud of pink smoke around the both of you then suddenly you both collapse and faint

Time later you wake back up in the dorms but you feel angry and mean then bakugo wakes up feeling kind and sweet while class 1a surrounds them

Aizawa: oh finally both of you are awake now there are some changes and you guys have swapped personalities
