Five years ago, Lu Qinghuan was framed by her family and fell into the deep sea while pregnant with Liujia. Five years later, she returned with her genius son Lu Xiaotuan, only to find out that she was pregnant with twins - the other child was adopted by Pei Changyuan, the youngest powerful official in the capital. Pei Changyuan, the chief minister of the dynasty who looks as gentle as jade, is actually a yandere with ruthless methods. His daughter Pei Nianan, who looked exactly like Lu Qinghuan, was her lost flesh and blood. When Lu Xiaotuan beat up the rich boy who bullied his sister in kindergarten, Pei Changyuan met for the first time this child who had "inherited" all his cruelty. DNA testing showed that Lu Xiaotuan was his biological child. What's even more fatal is that Pei Changyuan discovered that Lu Qinghuan was the woman he had been looking for for five years - the girl who gave him warmth when he was at his lowest and disappeared mysteriously. Nowadays, the selfish Lu family relatives are constantly creating misunderstandings in order to cling to the power of the Pei family. In order to protect his family, Pei Changyuan used his power for personal gain and used his power to oppress others, but Lu Qinghuan was also a tough guy. She took her two children and wandered in the whirlpool of intrigues, only to find that her biggest enemy was not an outsider, but this man who regarded her as his life and was paranoid to the point of morbidity.
