Ding Wu and his good friend Li Guo went to Shanghai on a business trip that day. Li Guo, who always regarded women as rubbish, kept chattering about how he easily hooked up women and threw them away fiercely. Ding Wu suddenly said, Pang Na would not be like that. Li Guo said that women are no exception. Ding Wu insisted that Pang Na would never do that. Later, in order to verify his correctness, Ding Wu turned back to Beijing before leaving the Shanghai airport. He wanted the truth to slap his friend. There are pure women. Her name is Bona. Then the most terrible thing happened. At home, Ding Wu found a man named Xia Li and took Pang Na with him. Sadness hit Ding Wu's heart like a bullet. Ding Wu despaired of love. He bet Li Guo and vowed not to kill Xia Li. Of course Li Guo couldn't stand by. He went to seek help from his university classmate Du Haifeng who worked in the Public Security Bureau. He wanted to know the situation of Xia Li. Ding Wu found through investigation that Xia Li is the boss of Panna Company, and Xia Li's wife, Chu Jie, is the boss of an advertising company. At this time, Ding Wu's sister Ding Yun, who was about to graduate from university, came to the internship unit. Li Guo asked Du Haifeng for help and arranged Ding Yun at the Public Security Bureau. Du Haifeng gradually fell in love with Ding Yun, and Ding Yun at this time also fell in love with Li Guo. Ding Wu wanted to retaliate against Xia Li by hurting Chu Jie, so he applied to Chu Jie’s company without letting Panna resign, and gradually won Chu Jie’s favor, but Chu Jie did not cross the line. Li Guo advocated hiring someone to kill Xia Li, but Ding Wu agreed. All arrangements are in order, Ding Wu and Panna are ready to travel abroad. Xia Li, who was besieged by the murderer, hurried to call the police. The police caught Li Guo. Ding Wu resolutely returned. In order to save Ding Wu, Panna endured the humiliation and had a relationship with Xia Li again. Xia Li promised to go to the Public Security Bureau to withdraw the civil dispute and protect Ding Wu. But in the court, Xia Li did what he said and framed Ding Wu. Pan Na stood up resolutely and complained that Xia Li had an improper relationship with her. Ding Wu and Li Guo were sentenced to imprisonment for intentionally wounding others. At this time, PONA found out that he was pregnant with Xia Li's child. Chu Jie couldn't tolerate Xia Li's behavior and divorced her. Panna reluctantly divorced Ding Wu for her child and married Xia Li. According to Ding Wu's arrangement, Ding Yun and Du Haifeng were married. A few years later, Ding Wu, who bore fruit, was released from prison one after another. There is a restaurant under the fruit plate, which is handed to Ding Wu. The stubborn Ding Wu refused. Ding Wudang hired a taxi driver. Inadvertently, Ding Wu met Chu Jie. From that day on, he took Chu Jie to work every day, and the distance between the two was getting closer and closer. Liguo found Ding Wu's diary on the computer, which had plans to kill Xia Li. Soon, Ding Wu's car killed Xia Li in a car accident. Du Haifeng vaguely felt that this was not a simple car accident, and all the signs indicated that it was probably a conspiracy to murder. In spite of Ding Yun’s objection, he launched a careful investigation and found out the amazing secrets hidden in it.
