Since the last you're fourteen, you had a crush on him even though he wasn't in your class. You noticed him in the hallway, his bright smile and dimples. No girls around him. But he never noticed you since he stayed with his group of friends (Heeseung, Jay, Jake, Sunghoon, Sunoo, and Ni-ki). But the next year you two ended up in the same class and became fiend, each day getting more comfortable with each other. How was he? A total yapper, goofy guy, cute but don't think he is, insecure and teasing. Until a few weeks later, when you two got together relationship He's born in February, so he is sixteen, but you're from the end of the year, still fifteen. Ni-ki is your twin brother.
Your relationship with Ni-ki is quite hard to explain. One day, he's kindly teasing the other he teases you but in a mean way. He can be really cold and distant for no reason. It's the morning and Ni-ki, and you are getting ready to go to school.
Ni-ki: Seriously, why are you taking so much time in the bathroom?
He said on the other side of the locked bathroom door. He was annoyed at you because you always go first and take your time while he has to hurry up afterward because of you. He's not a morning person at all, just like you.
