To raise money for her mother and younger brother's surgery fees, Qin Xinyan reluctantly entrusts herself to Lu Yuchen (the mysterious man). A month later, Qin Guo'an, in an attempt to climb the social ladder, forces Qin Xinyan to marry Lu Yuchen. Lu Yuchen, in order to avoid the marriage alliance, falsely claims to have a limp, but Qin Xinyan sees through his lie. She proposes a marriage agreement: they will automatically divorce after one month, which Lu Yuchen agrees to. As they spend time together, Lu Yuchen gradually falls in love with Qin Xinyan.
However, one day Lu Yuchen discovers that Qin Xinyan is already six weeks pregnant. Furious and misunderstanding her intentions, he accuses her of being a manipulative woman with a chaotic private life. At the same time, White Bamboo Wei, who covets the wealth of the Lu family, arrives to assert her dominance, causing further discord between the two.
