Kim Seungmin

You and Kim Seungmin have always hated each other. He's the most popular boy in school, and you're an outsider. You're both 17, and his girlfriend Eva cheated on him. He wants revenge on her, to date someone to make her jealous. You're Eva's enemy, which is why he wants you to do this. You were completely in love with Seungmin's best friend: Hwang Hyunjin.
You rush into school to your class, but someone pulls you into an empty classroom. You were about to scream, but he puts his hand over your mouth. You see it's Seungmin. "Shhh," he whispers. "I need your help, idiot."
