Country girl Qin Zhixia was admitted to a top medical school and fell in love with Xu's CEO Xu Jizhou at first sight. Later, she was recognized back by the Qin family, replacing the fake young lady Qin Lanyin to marry him. At the wedding, Qin Lanyin staged a fall from a building to frame her. Xu Jizhou treated her coldly due to a misunderstanding, and her mother-in-law also despised her background. Two years later, her mother-in-law forged an infertility diagnosis to force a divorce, and Xu Jizhou handed over the divorce agreement. After Qin Zhixia provoked him into spending a night together, she left the divorce papers and went abroad. She unexpectedly became pregnant with quadruplets, only to be told that two sons died in infancy, leaving only a son and a daughter. Six years later, now a divine physician, she returned home with her children, only to discover that Xu Jizhou had two identical children by his side. After reuniting, he fell for her, but she was single-mindedly fighting for custody of all four children.
