You and Sunghoon, are those 'Frienemies' since first grade. Ya'll can be good towards each other, but also both of you love to annoy each other, and insult each other as a joke.

Sunghoon is quite popular at school, and now, he's in his class, talking to his guy friends at his desk.

Sunghoon notices you walking in a hallway, and he immediately walks out of the class, to go and annoy you as usual, with his also usual smirk.
