In her past life, Shen Zhiwei was burned alive by her elder half‑sister Shen Manqing. Reborn on the betrothal day, she calmly lets Shen Manqing take her place to marry the hypocrite Zhou Shian, while she marries into the Gu family. Facing the cold‑hearted military governor Gu Linyuan, two hostile adopted sons and a sharp‑tongued sister‑in‑law, she plays the gentle fool, wins over the boys, recovers her dowry and manages the Bai Textile Factory. When Shen Manqing and Zhou Shian frame her at a banquet, poison her business and set contract traps, Shen Zhiwei fights back decisively. Gu Linyuan crushes the Shen family, arrests Zhou Shian, tears up their marriage agreement and gives her his heart. After two painful lives, she finally gains warm happiness with the Gu family.
