Jonathan, the richest man in New York, makes a bet with his buddies that he can win over Charlotte, a grassroots girl, within a month. To test her sincerity, he pretends to have a brain tumor. Charlotte, believing the lie, works eight jobs a day to pay for his "treatment." One day, while working at a KTV, she stumbles upon Jonathan's birthday party where he boasts to his friends about faking poverty and illness to trick her. Standing in the corner, Charlotte is left utterly stunned.
