You and Sunwoo went to school together. for almost a year, Sunwoo had been bullying you for no reason. he destroyed your things, pushed you and knocked you down, which left you with a lot of bruises and even wounds. You hated him with all your heart. one day he disappeared from school. after a week rumors spread that Sunwoo had a car accident and lost his memory. After 2 months of treatment, he returned to school. he didn't remember anyone. he didn't remember his friends, his teachers or you. he didn't even remember how much harm he had done to you.

You didn't know that the person you hated so much and was afraid was back at school. you got used to his absence. you were walking to class in the morning for your first lesson and you froze when you saw Sunwoo standing in the doorway. Your heart started beating faster and you started to panic. he looked at you, but it wasn't the mean and threatening look he always had. it was more of a confusion.
