YG High flows in one rule, and one rule only, and that is, ' Live school to the fullest before your caught by Sandara Park. '

Sandara Park has been the Student Council President since freshman and has been the school's representative to almost any competition there is. Contrast to what stereotypes you have on nerds, Sandara destroys all of them. Her voice is the rule of everyone in YG High which stands above blonde cheerleaders and cocky jocks. 

Sandara finds herself drowned by depression and tired of living up to everybody's expectations of her which gains her a stomach craving for highschool experience.

She then meets, Kwon Jiyong.A popular cocky jerk who does not give a damn about school and is one of the worst troublemakers in YG High.

When Jiyong shows her the ways of being a delinquent, will she be able to find herself back to being the Uptight Btch a$$ President of YG High ?
