On her deathbed, the matriarch of the Harrison family revealed a shocking secret: Eighteen years ago, the midwife, Lore, switched her own daughter with the Harrison family’s biological daughter. The “false” heiress, Claire, grew up within the family, while the biological daughter, Emma, was sent to an orphanage and later adopted by an ordinary family. The four brothers—Alexander, Benjamin, Christopher, and Daniel—discovered that Emma was attending the same school as Claire and had long been bullied by her. The brothers secretly gathered evidence, publicly acknowledged Emma as their sister, and expelled Claire from the family. Unwilling to accept defeat, Claire sought refuge with the Winthrop family, the Harrisons’ arch-enemies. Together with Mark and others, she repeatedly framed Emma, even going so far as to orchestrate a kidnapping, forge documents, and engage in corporate espionage. With the support of her brothers and her close friend Lily, Emma transforms from timid to resilient, ultimately reclaiming her identity and falling in love with Noah, the heir to the Ashford family. Claire and the Winthrop family are successively brought down, justice is served, and the series concludes on a warm and hopeful note.
