Disgusted by her poor, plain-looking fiancé Jiang Chen, she teamed up with her snobbish mother Lin Xiuzhi to trick her mentally challenged younger sister Liu Xuan into taking her place at the wedding so she could marry into the wealthy Zhou household. Jiang Chen’s family had spent all their savings for the bride, only to receive the innocent, simple-minded Liu Xuan. Filled with resentment at first, he treated her coldly. Though slow-witted, Liu Xuan possessed a pure, kind heart. Her unreserved trust and gentleness gradually melted the hearts of Jiang Chen and his mother Liu Sufen.

After all these hardships, Liu Xuan was showered with warmth by the Jiang family and safely gave birth to a son. From a scorned substitute bride deemed foolish, she became the beloved treasure of the whole family, finally embracing a happy life of her own.
