Du Lala (Xu Jinglei) is a white-collar worker who has just entered the workplace. Because her former boss always sexually harassed her, she decided to change jobs and joined the famous multinational company DB. Wang Wei (Huang Lixing), the gold medal manager of DB's sales department, and Rose (Mo Wenwei), the deputy director of HR, are a pair of underground lovers, but because both of them are under great pressure at work, neither of them has time to take care of their families, and the two sides break up generously. When Du Lala first came to DB, she met Eva (Li Ai) and Helen (Pace Wu) who were fighting each other. Because of a coincidence, she met Wang Wei, who suffered from claustrophobia, in the elevator, and the two became familiar with each other. Because the senior management of the head office was going to visit the Chinese branch, the general manager of the Chinese region and the HR director discussed renovating the company. However, Rose fell ill and needed surgery at this time, and others avoided it. Only the fledgling Du Lala took on the heavy responsibility and completed this important task with her perseverance, which was appreciated by her superiors. Moreover, the company also held a celebration party in Thailand, during which Du Lala and Wang Wei sparked love, but this office romance encountered many obstacles... This film is Xu Jinglei's fourth directorial work, adapted from Li Ke's best-selling novel of the same name.
