Xue Hai (Show Luo) is a certifiable dork who comes from a wealthy family and had been protected by his oldest sister, Xue Bo for most of his life. One day, at age 20, he decided to move out of his comfort zone and study abroad in Hangzhou. To protect his identity as the heir of his family's wealth, Xue Bo, gave him an alias "Lin Da Lang," who is supposed to be a poor student.
At Zhejiang University, Da Lang meets Chen Bao Zhu (Rainie Yang): an eccentric, friendless alpha-female social rebel. Lin Da Lang becomes unconditionally persistent for her friendship and endlessly delivers a peaceful and constant variable of support and acceptance to her neglected life. Unaware of Lin Da Lang's background, Bao Zhu teaches him the norms and social baby steps of every day life. As she begins to drop her guard, Da Lang vows to always be with her, and they fall in love. During this time, Chen Bao Zhu's father goes bankrupt and flees, leaving her and her mother behind. Using Bao Zhu's father as an example of poverty and failure, Bao Zhu's mother refuses to accept Lin Da Lang's relationship with her daughter and orders her to break up with Da Lang or she will prevent his graduation. Out of fear for Da Lang, Bao Zhu lies to her mother in a note, and agrees to an arranged marriage. Secretly, however, Bao Zhu plans to elope with Da Lang. At the same time, Da Lang - unaware of the conflict - wishes to propose and confess his true identity and wealth to Chen Bao Zhu. On Bao Zhu's birthday, Da Lang and Chen Bao Zhu make plans to meet, both unaware of each other's mutual objectives for a joint future. Da Lang purchases an engagement ring and heads to the meeting spot; but as Chen Bao Zhu leaves to meet Lin Da Lang, she is hit by a car and knocked unconscious for months. Da Lang continued to wait, but she never showed. Worried, Da Lang later visits her home, and Chen Bao Zhu's mother lies to him and reports she is in Europe and will soon marry someone else for money, showing him the note Bao Chu left. Unaware of Bao Zhu's true intentions, Da Lang comes to the conclusion he was recklessly abandoned by his first love. Xue Hai drops his alias of Da Lang, loses his simplistic innocent take on life, and vows not to ever commit to a relationship again.
Three years later, back in Kaohsiung, Xue Hai has transformed himself into an egocentric playboy who openly flaunts his wealth. Xue Hai overhears Bao Zhu's familiar voice on the radio as a local DJ, and feeling he is now unrecognizable, buys the radio station in order to seek revenge on Bao Zhu. Hiding his identity as Da Lang, Xue Hai plans to coerce Bao Zhu into falling in love with his new self, only to then dump her harshly in revenge. However, after seeing Bao Zhu with He Yan Feng (Lee Wei), her high-school senior/judo master, Xue Hai becomes jealous and soon realizes that he still has feelings for her. Xue Hai then sets his mind on destroying the relationship of Bao Zhu and her "boyfriend", while he continually pursues her, often forgetting whether it's out of love or revenge.
Still intent on finding her lost love, Da Lang, Bao Zhu is resistant to Xue Hai's advances. Xue Hai, knowing that he cannot begin a relationship with Bao Zhu unless she gets over Da Lang, lies and tells her that he has found Da Lang and that Da Lang is now happily married. Distraught, Bao Zhu flies back to Hangzhou to revisit, and hopefully bury her memories with Da Lang.
Back in Kaohsiung, college classmate Mo Lee visits the station. Mo Lee accidentally reveals to Bao Zhu that Xue Hai and Da Lang are the same person. Angry that Xue Hai has been lying to her all this time, Bao Zhu angrily tells Xue Hai that she never wants to see him again and plans to leave the country with He Yan Feng.
Before they leave, though, there is a fire in the radio station trapping Bao Zhu in the building. Xue Hai, wanting to save his love, rushes in but is hit on the head and trapped under a wooden beam while trying to protect Bao Zhu. Unable to get out himself, Xue Hai urges her to go and leave him and she is taken away by He Yan Feng. The firemen are able to pull Xue Hai out of the fire, but he is unconscious. Distraught over that fact that he is seriously injured, Bao Zhu is convinced that it is her fault. She realizes he truly loves her and that she loves him too, whether he is Da Lang or Xue Hai.
When Xue Hai wakes up, no one is there and he stumbles out of the hospital onto a toy store owned by mother and daughter. He has lost his memory, and unable to find his true identity, the mother and daughter kindly take him in. Xue Hai lives with the two in his old self Da Lang, having no idea of his actual identity. Bao Zhu searches for him for months, and finally stumbles across the store and finds Xue Hai, but discovers that he has forgotten everyone in his life - including her. Determined to get him back she brings him to many places that could remind him of their previous relationship. But after realizing that he does not remember her and in fact has started to like the toy store owner's daughter, Bao Zhu decides to leave with He Yan Feng to America. But before she has a chance to even consider it, Da Lang is kidnapped by his oldest sister's evil boyfriend and held for ransom. He is knocked out when he tries to escape and the blow to the head brings his memory back. However, he continues to lie about remembering Bao Zhu because he believes she is still with He Yan Feng and doesn't want to mess up her life anymore.
On Bao Zhu's birthday, Xue Hai, drunk, accidentally emails Bao Zhu a birthday greeting which reveals that he really does remember her. He wakes up in the middle of the night and, realizing his mistake, manages to delete the email on her laptop. However, Bao Zhu has already seen the e-mail and knows that Xue Hai remembers her. But she pretends she hasn't seen the e-mail, and asks Xue Hai to meet her later. That night, they meet and she reveals she knows he remembers her. She then proposes to him. Xue Hai accepts and the two get married and live happily ever after.
