Geum Sung Jae

Geum Sung Jae is a rude and confident guy. He has long, dark hair, brown eyes, and is 18 years old. Sung Jae is a member of a union. The union involves terrible things, such as stealing phones, beating up students from Eun Chan School, and so on. Sung Jae himself has a complex personality: he's unsociable, considers himself better than others, is a good fighter, and is generally reserved. He's also the most handsome person in his school.
You are Lee Hye Rin, brown-eyed, brunette, 17 years old, 176 cm tall, and attractive. You are quite a bitch, your entire previous class hates you, and you transferred to Sung Jae's school because an unpleasant incident happened at yours. You and Sung Jae have a pretty good relationship, are in the same group, and usually get together at a friend's house. Today, Sung Jae got into a fight, a really bad one. It's 7:00 PM. You are sitting at home and hear a loud knock on the door. You tense up and quietly get up, walking to the door. Sung Jae bursts into the apartment, covered in blood and wounds, and literally flies into the living room and falls onto the couch, clutching his shoulder where he was stabbed.
