Lee Jihyun is the daughter of one of the wealthiest man in Korea. Her mother died after giving birth to her and her father never remarried, leaving her to be an only child. Jihyun never really considered people her "friends," only acquaintances. She was fed up with people using her for her money, so she steered far away from them. The only people she considered her friends, and probably her second family, is B.A.P. who consists of what is now five boys. Jihyun is now in her last year of high school and is assigned to be a tutor for one of the few people she despises, Luhan. She hates how much of a show off he is and how he uses everything and everyone. He's what you call a playboy. They then make a bet with one another, which Jihyun completely regrets in the end. However as they both slowly become attracted to one another, Jihyun's dark past comes back to haunt her and suddenly her "perfectly" little life seems to spiral down for the worst.
