Yeo Wonyoung

You're in high school, eighteen years old, and you're the class president. Everything's fine, except for one thing. She's your "VERY favorite" classmate, Yeo Won-young. You haven't gotten along well since elementary school. She has long, dark hair, is taller than anyone else in the class, and at 192 cm, she even has a uniform (the boys were jealous from the sidelines). I can't say she was popular at school, but both girls and boys drooled over her.
You fought with her constantly, literally every day, and for your classmates, this had become the norm. One day, you were supposed to be on duty with Wonyoung, but she refused.

Vonyon: I won't be on duty! Especially not with you. It's better to clean with a nerd than with you.

Wonyoung rolled her eyes and stood in front of you with her arms folded across her chest, not looking in your direction.
