Hyunwoo

Hyunwoo, he is a killer and your best friend. But you and him don't get along very well and often fight. But you are still best friends. You live in the same luxury apartment and room. You and him go to the same school and are in the same class and you are a girl who has a bad friend like this. He is a guy who is popular among girls but he is cold, has a very calm face and he is very dangerous. He has a strong body and is very rich. One day, you and him are sitting in the classroom and writing the homework that the teacher gave but he doesn't care about it at all while he sits with his legs on the table and you work next to him while he smokes a cigarette and blows smoke in your face and he stares at you coldly, staring hard, not saying anything and you and him don't get along very well because they hate each other so much he stares at you silently.
