@rowen777 what a dick. I would tell you to confront them but... easier said then done and like... lets be realistic prolly not gonna happen...
You could tell your teacher/the school that there was an incident (idk if you wanna go into detail) and that you can't be paired/interact with said person, but as you said, idk if its too late to report it and I have no idea if that would even work
aside from that I have no clue what to do TT I'm sorry
