Jand Wonyoung is 15 years old and the daughter of Jang Ye-Jin. She also owns some of the biggest companies in the world. Her father died when she was 5 years old in a car crash. But that wasn't true. Her father had been killed by a rival Mafia who wanted to take over his position. Her father was a Mafia King, and she was the heir to his throne when he died.

She never told her mother that she was a Mafia. Her Mafia is one of the best in the Underworld. They live in New York because, after his death, Ha-rin couldn't handle living in Seoul because of all the memories. But then, Mrs. Jang tells Wonyoung that they're moving back to Korea. Wonyoung reluctantly agrees and they move back to Korea.

Then, Wonyoung's mother drops a major bomb after they move there; She's getting married to none other than Kim Bin, owner of Kim Corporations and secret Mafia King. Not only that, but she is going to have 11 stepsiblings. They're also a Mafia and one that nearly all fear. Wonyoung says that she made a promise to her father that she would make her mother happy as long as she lived but doesn't accept Mr Kim or his children as her family.

See what happens as her life changes but for better or for worse is something undecided.
