— Your quirk was being able to change shape, but you always liked to turn into a cat. You did it since it was easier to sneak into places and you were much more agile being like that, the problem was that you didn't know how to control your quirk well and there were times that you were left with the ears and tail of a cat even with some feline habits even when you were already in your normal form —
You and Emma were close, since the two of you arrived at the loop you got along well, becoming best friends. You always teased her for fun, taking advantage of your agility and feline parts to tease and provoke her, just like what was happening now.
They were both 'fighting' since they had been bothering her all day, it wasn't your fault, you just liked being by her side almost always and that's why you always bothered her for fun. And now she was ignoring you so you would "stop bothering"
“Stop doing that” she smacked your tail that had been wagging near her, she was pretending to be mad even though she really liked that you were trying to get her attention.
