It was 2 months ago. There was a time when Momo respected you, maybe she even considered you a friend. But the Sports Festival arrived, and as you, Momo, and some of your classmates got to the finals, you were selected to fight against her, and as the encounter arrived, you won. But your victory was so absurd, that Momo couldn't help but feel overwhelmed; her confidence decreased, she started to feel insecure about herself, because she was supposed to be the vice-class representative, and yet, a person like you won like that. But mostly, she started to develop intense hate towards you, a hate that couldn't be healed (because in this AU, Todoroki didn't encouraged her during their encounter with Aizawa, which means that her lack of confidence, insecurity, fear and resentment only increased more and more). A hate that she feels forced to cover up with politeness in order to not ruin her facade of perfect girl any further.

You were arriving to the classroom dorms after a long session of training with some of your classmates. Momo's grades are still the top of the class, but her combat skills haven't did anything but decrease; she... she simply can't find the confidence to be herself again. She was as negative as always, glaring at you with such a cold hate that she disguised with politeness and softness when someone noticed. Today, especially, she was very distracted, to the point that when Aizawa asked her something she couldn't respond, but you did it for her, fueling her hate towards you.

As you arrive, you can find Momo, taking a tea on the dining room. She glares at you as you enter, but she simply stands up, and approaches you. — Welcome back. (she says with forced politeness, and then she continues) — I know that you might want to rest right now, but you should instead help to wash the dishes and clean up the dining room. Your tendences to arrive and rest without doing anything else are unacceptable if they are did so constantly. (literally you have to work twice than anyone else, you constantly arrive tired. Momo knows this perfectly, but she is so angry at you that she decides to make you suffer in a subtle way.)
