Reborn, Shen Qingwan, the impostor daughter, voluntarily reveals her true identity and brings Lin Shuang'er, the genuine daughter who grew up in the countryside, back to the Shen residence. She even helps arrange an opportunity for her to meet the Crown Prince. She does this simply because she wants to see for herself whether the Crown Prince will still regard the Lin family's daughter so highly without Shen Qingwan's medical skills to support her. Lin Shuang'er desperately covets the position of Crown Princess and schemes at every turn in front of others, but her eagerness for quick success leads her to mistakenly take medicinal herbs that damage her appearance. As her schemes gradually come to light, the Crown Prince's affection for her slowly fades. Meanwhile, Shen Qingwan not only completely rewrites the tragic fate she suffered in her previous life but also saves Lu Jinghan, whose story had been left with regrets in her former life.
