In her past life, Shen Zhiyi was framed and murdered by her fiancé Gu Chenze and stepsister Shen Ruolin, leading to her mother's death and the usurpation of her family assets. Reborn back to the engagement banquet, she publicly broke off the engagement and chose to enter a contractual marriage with Gu Yanzhou, who had chronic illnesses and a higher seniority generation. Together, they dug deep for the truth, exposing Gu Mingyuan and Zhou Man's conspiracy of plotting two car accidents and devouring both families' assets, and collected complete evidence to topple all enemies. As the revenge came to an end, the contract couple developed genuine feelings, held a real wedding in the original banquet hall, and joined hands to start a new life.
