In order to repay her mother's medical expenses, the down-and-out daughter Su Tang was forced to work as a cleaner in the Gu Group. She unexpectedly met Gu Yan, a second-generation rich man who pretended to be an ordinary employee to experience life. Gu Yan uses humor to break Su Tang's cold barrier, and the two gradually fall in love. However, due to the return of Su Tang's first love, the yandere painter Shen Yan, and the intervention of the marriage partner arranged by Gu Yan's family, the green tea socialite Lin Wan, they fall into a sadistic love triangle. The three of them were repeatedly pulled together in misunderstandings, lies, and redemption. In the end, after Shen Yan's self-destructive entanglement and Lin Wan's conspiracy were exposed, Gu Yan used the clumsiest sincerity to tear apart all disguises and rebuild their broken love with Su Tang.
