Zhao Wangshu is an ordinary employee in the administrative support department of Yulin Group. Like most girls, she is a girl who loves to dream. After entering the workplace, Zhao Wangshu discovered that reality was far from as beautiful as she thought. Until one day, Zhao Wangshu was dispatched to the general manager's office as a specialist of the administrative support department to participate in the "Brilliant 99" project. She met Xu Yonglin, the general manager of Yulin Group, for the first time. In the future work, Xu Yonglin was gradually attracted by this simple and kind girl, and he was tempted again. However, Zhao Wangshu hesitated about Xu Yonglin's pursuit. The disparity in family background made Zhao Wangshu full of fear of this relationship. She broke up with him.

Just as Zhao Wangshu was preparing to accept Xu Yonglin's pursuit, Lin Yuhao, a college classmate who had pursued Zhao Wangshu, returned. Lin Yuhao became a tour guide for a travel agency after graduating from college. His arrival revealed another secret that had been sealed for many years. What will be the final outcome of this battle for love?
