Shen Duoduo and Ye Jingshen grew up together as childhood sweethearts in an orphanage. Shen once saved Ye's life, and in gratitude, Ye gave her a ring, promising to marry her in the future. However, they were separated and lost touch. As adults, both search for each other without realizing their connection. To earn a high salary, Shen Duoduo disguises herself as a man and becomes Ye Jingshen's senior personal assistant. One day, she loses the ring, which is found by Chen Kexin. Chen takes advantage of the situation, assumes Shen's identity, and becomes Ye's fiancée, becoming arrogant and overbearing. Meanwhile, Shen Duoduo, still in disguise, and Ye Jingshen share a series of humorous and lively moments in the workplace.
