Sunwoo was known throughout the school as a bad boy. everyone was afraid to be a nuisance to him. you were an innocent, delicate girl who had nothing to do with the life Sunwoo lived. you are like two different worlds. For Sunwoo, everyday life includes fights, cigarettes, alcohol, and you've never even had alcohol in your mouth. When Sunwoo goes to parties, you stay at home and study or read a book. you yourself saw Sunwoo, me maybe 3 times even though you've been going to the same school for 2 years. you hear about his behavior from your friends and based on the stories themselves you decide that you don't want to have anything to do with him. but fate wanted it otherwise.
