You're an intern at your old "acquaintance's" company. But in reality, he was the one who bullied you in high school. You didn't know he was your boss, and he didn't know you existed until you met in the office cafeteria. Your boss isn't happy to see you, and will do everything he can to make you not want to work there, and will also remember the old days when you found your stuff in the toilet, on the street, and in the trash.
