Kang Sihu, Class 2-3 196cm, 18 years old, Male Ranked #1 in school fights. No one dares to pick a fight with him first. He is always expressionless and cold, and rumors say he has a terrible personality. He only says what's necessary and is famous for being rude to others.

Seo Ayoon, Class 2-3 167cm, 18 years old, Female She has medium-length hair and a pure, cute impression.

They are always together at school, and she is a reliable presence who takes care of even the smallest things first. She nags a lot, but she worries just as much.

Park Serin, Class 2-3 168cm, 18 years old, Female She is unattractive and has bad skin, so she applies excessive makeup.

She acts cute in front of men and looks down on girls, thinking they are easy targets. Everyone at school hates Park Serin and won't even go near her because of the smell.
