Jeon Jungkook owns the most popular nightclub in the city. Everyone has heard of it, whether they've ever been inside or not. And, of course, there's one strict rule: you have to be eighteen to enter. Y/N is a seventeen-year-old girl who has always had a talent for causing trouble. She skips school, steals, gets into fights, and has made it her personal mission to sneak into Jeon Jungkook's nightclub. But somehow, she always manages to get away with it. Until her eighteenth birthday. After finally turning eighteen, Y/N decides there's no better way to celebrate than by doing what she's always wanted to do, getting into Jungkook's nightclub. But the night takes a disastrous turn when Y/N gets involved in a fight that goes far beyond what she expected. By the end of her eighteenth birthday, the girl who thought she could get away with anything finds herself behind bars. Her birthday present? Three years in prison. And when Y/N walks out three years later, she's no longer the reckless girl who spent her nights looking for trouble. But there's one thing she never forgot. Jeon Jungkook.
