Xue Hai (Show Luo) is a boy who comes from a very wealthy family and has been protected by his family all his life. One day he decides to move out of home and study abroad in Hangzhou. Xue Hai's oldest sister helps give him the alias of Lin Da Lang, a supposably extremely poor student, in order to protect his identity. In Da Lang's new university, he meets Bao Zhu (Rainie Yang) who protects him from bullies who tease him for being a dork.
In turn, Da Lang promises to be Bao Zhu's close friend and they eventually fall in love with each other. After Bao Zhu wins a "Sweetheart Queen" competition, she becomes known as the school "Sweetheart", but during this time, Bao Zhu's father goes bankrupt, flees, and leaves her mother behind. Using Bao Zhu's father as an example of failure, Bao Zhu's mother forces Bao Zhu to date someone wealthier, so she tells her to break up with Da Lang.
After promising a date with Da Lang and escaping her mother, Bao Zhu is hit by a car and rushed to the hospital before Da Lang is able to prove his wealth with a wedding ring. While Bao Zhu is undergoing surgery, Da Lang calls her because she did not come to the date on time but Bao Zhu's mother picks up the phone instead.
Because she does not know Da Lang's true identity, Bao Zhu's mother lies to Da Lang, telling him that Bao Zhu has gone to Europe for an arranged marriage with a wealthier person. Due to this misunderstanding, Bao Zhu and Da Lang lose contact. Thinking that he got dumped by his first love, Xue Hai drops his alias as Da Lang.
Three years later, Xue Hai has become a play-boy with a makeover. After hearing Bao Zhu's familiar voice on the radio as a DJ, Xue Hai decides to buy the entire station in order to be Bao Zhu's boss and seek revenge. However, when Xue Hai sees Bao Zhu dating other people, he comes to realize that he stills loves her.
