Chen Jiaqiao, played by Wu Zhenyu, is the owner of a company. She is married to Swallow, played by Yu Nan, and coco, played by Jiang Yiyan, is Wu Zhenyu's lover, but Jiang Yiyan doesn't know that Wu Zhenyu is married. Yu Nan used to be the head nurse in the maternity hospital, and she was very happy when she found out she was pregnant. Once, when she was waiting to cross the street after buying vegetables, she saw Wu Zhenyu's car in the distance and found Wu Zhenyu and Jiang Yiyan making out. She walked over there and was knocked down by the car, aborted and had her uterus removed. So Yu Nan began her revenge plan. (In the film, Yu Nan is a calculating and intelligent person. In short, she found the information about Jiang Yiyan, and how did she do it? The film didn't write it.) Wu Zhenyu likes eating very much, but Jiang Yiyan can't cook. Once, they had a quarrel, and Wu Zhenyu made a dash for the door. At this moment, Yu Nan found Jiang Yiyan, approached Jiang Yiyan with a fake name, taught her to cook, lied that she was the host of the radio food festival, and gave Jiang Yiyan a cookbook and a recording of cooking. Jiang Yiyan started cooking for Wu Zhenyu according to Yu Nan, and Wu Zhenyu liked it very much, so their relationship became better and better. However, gradually, Wu Zhenyu's body began to have problems, but he couldn't find any problems when he went to the hospital for examination. Wu Zhenyu and Jiang Yiyan started to make trouble again because of this matter, and Jiang Yiyan complained to Yu Nan. Jiang Yiyan went to the bookstore and found the book about the food festival that Yu Nan said. When she opened the front page, she found that the author's photo was not Yu Nan, and she began to have doubts. Wu Zhenyu's health is getting worse and worse, and he fainted in the company. Yu Nan took him home from the hospital to take care of him, but actually put him under house arrest. Jiang Yiyan continued to search for information on the Internet and found a video. She saw the real radio host, and Yu Nan also appeared in the video. It turned out that she was a loyal fan of the host. At this moment, Jiang Yiyan knew that Yu Nan had been lying to her, so she asked Yu Nan out and followed her. Yu Nan also knew Jiang Yiyan's suspicion and tracking, and waited for him at home. Only then did Jiang Yiyan know that Wu Zhenyu and Yu Nan were husband and wife. Yu Nan told Jiang Yiyan about her revenge plan: the recipe she gave Jiang Yiyan was actually only half of a book, and the other half was in her own hands. The food she taught Jiang Yiyan was similar to the soup she cooked. If Wu Zhenyu ate it at the same time, his body would eventually collapse. Jiang Yiyan thinks Yu Nan is horrible. Jiang Yiyan lived in a house given to her by Wu Zhenyu. She left the key in the newspaper box and said goodbye to Yu Nan. At this moment, Yu Nan found that Jiang Yiyan was pregnant. Jiang Yiyan was ready to leave. He got a call from Wu Zhenyu and wanted to meet him. Jiang Yiyan agreed. When they arrived at their home, Jiang Yiyan found that Wu Zhenyu was lying to her, because Yu Nan said that as long as Jiang Yiyan could be found, Wu Zhenyu would be released. Yu Nan put Jiang Yiyan under house arrest until she gave birth to the baby. Yu Nan went to Wu Zhenyu Company to announce Wu Zhenyu's illness and entrusted the company to others, when she found a safe in Wu Zhenyu. When she got home, she asked Wu Zhenyu for her password, but Wu Zhenyu didn't say anything. Yu Nan tried it out by herself. It was full of photos of Wu Zhenyu and different women, and the feeling of getting along with this woman was written on the opposite side of the photo. Jiang Yiyan saw his photo and the negative words, only to know that Wu Zhenyu didn't love him at all, just playing with her. When Wu Zhenyu's secret was revealed, he committed suicide. Yu Nan pushed Wu Zhenyu's body to the rooftop, thinking of what Wu Zhenyu said to her when she got married, and jumped down. Jiang Yiyan gave birth to the baby and started a new life.

At the end of the film, the husband of the real host of the radio food festival was found to have a lover by the media, and soon he died of poisoning, and the host also jumped to his death, just like Wu Zhenyu and Yu Nan.
