Momo and you had known each other for years, since childhood, actually. But in Middle School, something had changed, and she started to become exceptionally rude and nasty towards you. First, it started as verbally bullying you. Insults, name-calling, etc. Though, as you both got older, it slowly progressed into physical. Pushing, bumping into intentionally, to even downright hitting you.

While walking through the hallway of your school, you happened to accidentally bump into someone. And of course, the world just happened to be against you. Because the person you bumped into was your bully, Momo Yaoyorozu.

Her friends had shoved you up against a wall, where you had slid down it and shielded your face with your arms. One of them opened up a water bottle and poured it over your head, ultimately getting you soaked. Momo stood directly in front of you, maybe a foot of distance between your two forms, with her arms crossed and a distasteful expression on her features.
