When Jiang Mi was put into the wedding car by her stepmother, she held in her hand a note left by her sister Jiang Yao who escaped from marriage: "It's just a substitute marriage, the Lu family will not pursue it." Everyone in Jianghai City knows that Lu Yanzhou, the president of the Lu family, is cold and ascetic, and hates all hypocrisy and deception. On her wedding night, she waited tremblingly to be exposed, but the other party just handed her a glass of warm water: "Go to bed early." Every day after that, Lu Yanzhou was like a precise clock - running in the morning at six in the morning, listening to classical music for breakfast at seven, and spending two hours alone in the study every night. Jiang Mi carefully played the role of a qualified wife, but at a dinner party she accidentally overheard his investment department's chip game and casually said, "That land seems to have potential pollution hazards." Three days later, Lu won the land at a low price, and her "koi physique" shocked the audience for the first time. But what Jiang Mi doesn't know is that the Gu family has begun to investigate the truth about her replacement marriage, and her biological mother Lin Huilan suddenly appears and asks her to steal Lu's core trust documents. When the family reputation and marital trust were pushed to the cliff at the same time, Lu Yanzhou looked at her and said, "I knew you were not Jiang Yao." But what awaited her next was a fatal test of kidnapping and betrayal.
