Plot
Nan Yi, a medical genius, was framed by the second young master of the Si family, losing her innocence and giving birth to twin sons. Her father used the children to coerce her into taking the blame for the second young master Si, leading to her imprisonment. Six years later, after her release, she was forced to marry Si Mohan. Si Mohan, the eldest son of the Si Group, was in a coma due to poisoning. Si Shengjing plotted for Nan Yi to marry into the Si family as a good luck charm, intending to seize the family assets. Nan Yi protected herself by waking Si Mohan, but he didn't acknowledge her and agreed to a divorce three days later. Upon returning home, Nan Qiuhang claimed her younger son was dead. Nan Yi didn't believe it and suspected his identity due to a birthmark on Sui Sui and a scar on Si Mohan. Si Mohan misunderstood, denied it, and told her not to pay attention to his son, Sui Sui, leading to Nan Yi's disappointed departure. Nan Yi disguised herself as a 'Ghost Doctor' and held an auction to retaliate against the Nan family, seizing the opportunity to rescue her son, An An. Si Mohan suspected her identity as the 'Ghost Doctor' and wanted her to treat his leg. Sui Sui got lost and met An An. Si Mohan confirmed Nan Yi was the 'Ghost Doctor', but changed his mind due to Nan Yi's care for Sui Sui, fell in love, and no longer wanted a divorce. Nan Qiuhang's threats to Nan Yi were exposed, and Nan Yi searched for her younger son. It turned out that six years ago, Shen Qiuyu impersonated Nan Yi and claimed to be the one with Young Master Si that night. Si Mohan learned Nan Yi went to Lincheng and also went, wanting to buy full custody of Sui Sui. Shen Qiuyu sent people to ambush Nan Yi, but Si Mohan took a knife for her. Nan Yi was moved and cured his leg. Shen Qiuyu's subordinate lied to Nan Yi that her younger son was dead. An An was critically poisoned, and Si Mohan risked his life to find herbs for the antidote, leading Nan Yi to accept him. The Si family acknowledged Nan Yi's status. Si Shengjing, out of jealousy, threatened Shen Qiuyu to stir up trouble and tampered with the paternity test report. Si Mohan and Nan Yi teamed up to capture Si Shengjing, but An An was poisoned again, and the antidote was destroyed. At the critical moment, Nan Weiwei brought the antidote, and a paternity test proved Nan Yi was Sui Sui's mother. Everyone reconciled.
