The Shen family, a well-known medical family in the south of the Yangtze River, due to the ancestral motto that "it is difficult to raise a legitimate daughter", twin siblings Shen Zhiwei and Shen Zhiyan exchanged identities and grew up. The daughter pretends to be the young boss "Shen Yan" to run the drug store, and the son disguises himself as "cousin Shen Wei" and hides in the boudoir.
