- Qin Fen (Ge) is a man in his late 40s who returns to China after many years overseas. He becomes a multimillionaire after selling an "innovative invention" to a high-profile (but foolish) angel investor (Fan). With his new fortune, Qin decides to put an end to his bachelor life and advertises open invitations to potential partners online, citing only "if you are the one", which actually means "don't disturb if not sincere".
Subsequently, he encounters various candidates from a homosexual former friend, a cemetery saleswoman with a thick south-Chinese accent, a pathological amnesiac, an ethnic minority pecking hen, an erotophobic widow, an expecting single mother, to a stock-holding trader. Eventually, he crosses path with air stewardess Liang Xiaoxiao (Shu). While helping Liang get over her agonizing love affair with a married man (Fong), Qin strikes up an unexpected friendship with Liang, which eventually blossoms into love during a trip to Hokkaido.
