Mia, a girl from a poor family, envies Wendy, the legitimate daughter of the Su family, and steals Wendy’s ten years of life with a fate-swapping system. After suffering a decade of hardship, Wendy gets plastic surgery and returns under a new name to take revenge. She lures the greedy Mia into another fate swap, and the system backfires, leaving Mia deep in debt and aging rapidly. Wendy regains her identity, reconciles with her parents, builds a successful career and finds true love. She rejects the system’s tempting offer, while the system lurks in the city for another greedy soul.
