On the eve of his wedding, Chen Chuan accidentally discovers that his fiancée of six years, Lin Man, has just held a wedding ceremony next door with her ex-boyfriend, Gu Mingxuan! When confronted, Lin Man claims she was merely helping her seriously ill ex fulfill his dream. However, a marriage certificate exposes her lies completely. As the two grooms confront each other face-to-face, an elaborate scheme involving two sets of wedding gifts, money fraudulently obtained to buy a commercial property, and an attempt to seize real estate is gradually exposed. The two men, who were initially at odds, decide to join forces to expose the scam and recover their money. Despite Lin Man's desperate pleas, Chen Chuan resolutely ends their six-year relationship and begins a brand-new life.
