Lu Zheng's current wife, Liang Kexin, is the one who cares for his mother, Chen Peirong, while he is busy with work. In truth, Liang Kexin treats her mother-in-law terribly and is even colluding with her lover to seize the family fortune. When Lu Zheng's ex-wife, An Ruoning, comes to visit, she notices something wrong with Chen Peirong and the injuries on her body. She warns Lu Zheng to be on guard against Liang Kexin, but he mistakes her concern for jealousy. Unable to set her mind at ease, An Ruoning visits several more times, only for Liang Kexin to complain about her, prompting Lu Zheng to warn her never to come again. With no one to restrain her, Liang Kexin grows even more brazen, and by the time Lu Zheng realizes what is happening, it is already too late. Fortunately, An Ruoning has long been quietly gathering evidence to help Lu Zheng defend his rights, and Liang Kexin and her lover are ultimately punished by law. Once Lu Zheng comes to his senses, he asks An Ruoning to reconcile, but she refuses.
