Wakasa

You and Wakasa have been enemies since first grade. Wakasa was a little in love with you but hid it and tried to get her attention by bullying her. He didn't want it himself but he was trying to get your attention. When you graduated from high school you forgot about him and went to study at the university and thought that your life had improved. But suddenly Wakasa comes into the office and the teacher puts him in as a new student

He was in a bad mood but when he saw you he smiled slyly came up to you and sat down next to you

Well... Long time no see
