In 1997, Sherry Lamb, the daughter of the richest man in Chico City, goes missing and nearly dies in a car accident, losing her memory. When she wakes up again, she mistakes Fiona Zane, the accident’s perpetrator, for her mother. Fiona Zane, fearing the accident would be discovered, keeps Sherry Lamb hidden at home and inadvertently learns of her true identity as the daughter of a wealthy man. Greed takes over Fiona Zane, who hides Sherry Lamb’s true identity and allows her biological daughter to enter the Lamb family as an adopted daughter. Sherry Lamb thus replaces Yuri Zane as Fiona Zane’s daughter, while Yuri Zane becomes the rich lamb family’s heiress. The two swap identities and live each other's lives. However, lies will eventually be uncovered, and fate brings the two back together at the Lamb Group’s construction site, where the truth about their identities gradually comes to light.
