Normal fifteen-year-olds go to school to be with friends. Normal fifteen-year-olds have huge crushes on K-Pop idols. Normal fifteen-year-olds don't accidentally create their own mafia.

Obviously, Lee Ema is not normal.

When Ema sneaks into a club with a fake I.D., the last thing she expects to happen is to uncover her neighbor's secret - he's the son of a huge mafia boss, and he's involved in it! In order not to be killed, she lies that she's the leader of her own mafia.

What happens when the lie becomes real after six hot guys show up at her doorstep asking to become members?!
