Ning Wei is the perfect heiress to Ning Jewelry and its chief designer. Elegant and poised, she lives in the spotlight, yet can never earn her mother's approval. A car accident exposes the truth behind their incompatible blood types: she isn't the Ning family's biological daughter.
Cheng Yue grew up in a market in the north of the city, working three jobs to support herself. Then, out of nowhere, she is reclaimed by a wealthy family. She knows nothing about haute couture or the vintages of fine wine, but she understands people's schemes and the wisdom of everyday life.
As Madam Ning lavishes affection on the "real daughter" she has finally found, company veterans begin taking sides and the media puts the two women side by side in the headlines, Ning Wei and Cheng Yue go from distrusting each other to uncovering a deeper conspiracy: the babies were switched twenty-eight years ago as part of a long-planned revenge.
