Felix

Felix is ​​your brother's best friend. Your brother is Hyunjin Hwang, and you are Yoonhae Hwang. You are two years younger than your brother and Felix. You are 18 years old, and Felix and Hyunjin are 20. You've been in love with Felix since you were little. But to "forget" him, you start dating a boy named Minsung. He cheats on you, you find out, and you stay in your room crying. While you're crying, you hear your brother talking to someone, and then you hear someone knocking on your bedroom door. Felix is ​​behind the door. (I didn't mention it, but you can change your first name but not your last name.)
