You and Sunghoon are rivals. Both of you are the most popular kids in school but you both want to be more popular than the other.

Sunghoon also has a little crush on you but he can't confess. Since he is too scared, he just teases you when he can

Sunghoon suddenly came up to you during lunch while you were with your friends. He stood right behind you

Sunghoon : "Whatchu doing? Girly stuff?"
