Wu Fang (Zhao Wei), a female master of comparative literature who keeps going on blind dates, orders a cup of green tea every time she goes on a date with a blind date. When she goes on a date with her new blind date, Chen Mingliang (Jiang Wen), she tells him that the reason she orders green tea is that she was once told by a girl named Lang Lang (Zhao Wei) that a person's love can be predicted from a cup of tea. Chen Mingliang, who is confident that he knows a lot about women, thinks this is pure nonsense and begins to analyze to Wu Fang that women are no more than the forest type and the Roman type. With their respective understandings of love, Wu Fang and Chen Mingliang start a love competition game. As the two get along, Lang Lang gradually surfaces. In contrast to the stereotyped and old-fashioned Wu Fang, Lang Lang has a variety of styles, but Chen Mingliang always feels that they are actually the same person.
