Ma-te's mother gives it instead to Hong Yoo-ra (Han Chae-young), an ex-heiress who was once the daughter-in-law of a wealthy family.

Yoo-ra promises to give him the password if he conquers several women and learns valuable lessons from each of them so as to conquer Na Hong-ran, Yoo-ra's ex mother-in-law and the Chairman Park Ki-suk's wife, who is evil and ruthless.

But then Kim Bo-tong (IU), an ordinary girl from a poor background decides to aid Ma-te in pursuing his father's heels.

But Choi David (Lee Jang-woo), who is also the Chairman's secret son and is like the male Bo-tong, falls for her too, leading into a conflict of romance and deception.
