Song MinAh was THE baddest girl at SK High School. However, despite her image, she had brains and was a beauty. Everyone was afraid of her. Her father is the CEO of SK Group and her mother was her high school principal. No one new her true identity. They just made up stories about her background. There was even one story that her father was a gang leader and her mother runs a room salon. MinAh didn't want anyone to know her true identity as an heiress to one of the top companies in South Korea. Instead, she wanted to live a normal life. She begged her mother to not release her true high school rank to the public because she wanted to keep her bad girl image. Her parents' didn't question her motive, and just went along. The reason? DO.Kyung.Soo. Kyungsoo was the smartest guy on campus. He wore thick framed glasses, always had a book in his hand, and walked with a straight posture. Kyungsoo was always quiet, but there was something about him that caught MinAh's attention. Being the high school girl that she is, she didn't know how to express her feelings, instead she attempted to make him her victim. Instead, he would ignore her. 

Two years later, as MinAh was on her way to Seoul University for her first year, she received a group chat from her high school classmates.
