Shen Qingci, the legitimate daughter of the Duke of Zhenguo, was sent away by her grandmother and concubine when she was young, and she wandered away for ten years. When he returned to his hometown in the 1990s, he found his biological mother imprisoned, her family property taken away, her concubine taking advantage of her marriage contract, and her concubine taking over the family. Without a golden finger at his side, Shen Qingci relied on the mind and means he had developed over ten years to work step by step: first, he exposed the concubine's fake talent and regained the initiative in the marriage contract; then he searched for evidence to rescue his birth mother and exposed the concubine's crime of embezzling Mo's family property; and when his grandmother made things difficult for him, he used arguments to fight for the right to control the family. From an "outsider" who was bullied by others, to a legitimate mistress who shocked the whole family, Shen Qingci used her strength to tear apart the disguise of a top relative, protect her biological mother, guard the family business, and live out the supreme dignity that a legitimate daughter should have.
