Shen Zhiyi was forced to marry into the Yongning Hou Mansion. Faced with her eccentric mother-in-law Liu, her hypocritical concubine Shen Ruowei, and the sidelines who coveted the family property, she worked step by step: using accurate accounts to uncover the corrupt housekeeper, using rules to resolve her mother-in-law's difficulties, and using her wits to expose the concubine's evil schemes. Lu Jingyuan watched with cold eyes at first, but was moved by her intelligence and courage. He blocked arrows for her in front of others and supported her while washing her hands and making soup behind others. From mutual testing to mutual trust, Shen Zhiyi, under the protection of Lu Jingyuan, stabilized the backyard of the Hou Mansion, helped him consolidate his power, and eventually became the mistress of the Hou Mansion that everyone envied, composing a sweet legend of the legitimate daughter in charge of the house and the exclusive favor of her husband.
