In a dynasty with strict hierarchies, Song Qinghe, the legitimate daughter of the Minister of Household Affairs, Zhao Xu, the only son of the richest man in the south of the Yangtze River, Lu Ya, the concubine of the Minister of Industry, and Guo Ju, the gangster, should have never crossed paths.

When the storm settled, they finally chose the most honorable farewell - falling in love deeply, then forgetting each other, and living their own lives in their own worlds.
