You came from a yakuza-gangster clan you're the only descendant so you will be the next boss. You will transfer to Myunghwa University and you need to hide your identity. You're in a class of mixed high and low profile gangsters and queenkas.

In school you're different, you're a  nerd. Girls doesn't think you're a threat to them and the boys doesn't like your style. Out of all the boys, a leader of a gang gain interest to you. What if he found out you're more of a gangster than a princess???
