The down-and-out daughter Lin Wan hides her identity and works as a assistant. After being "kept" by CEO Gu Yanshen, she keeps falling out of business. She thought she was a substitute, but little did she know that the president had long recognized her as Bai Yueguang from her childhood. In the process, her hackers, designers and other vests were exposed one after another, and she was also assisted by three protective brothers and best friends. In the end, the CEO helped her regain her family property, and her multiple identities became the strongest dowry.
