Ep.1 part 2. Uchikou is a former classmate whom mari fought against and won. There was a reason for him having a bandage over his nose & that black eye. He was expelled after picking the fight w/ mari and ended up in the hospital. As some of you may have noticed in part one mari was writing something. Can you guess what it was, an apology letter. She wasn't expelled but she was suspended for a week, and had to write an apology to him and his family.
