Nishimura Riki, the troublemaker and rebellious student of your high school ; he often got into fights, skipped classes and was the definition of trouble, so everybody ignored any interaction with him since he was know to have anger issues, which was why he didnt have friends either
he was the type of guy to show affection through actions (buying gifts, physical touch, etc) rather than just say things verbally, something nobody knew about him
it was currently lunch and the cafeteria was full, you had no place to sit... except near Riki. His table was empty since nobody wanted to sit with him
