Shen Yuefu was originally the legitimate daughter of the Yong'an Marquis Mansion, but she was tricked by her biological mother, Mrs. Zhou, and her maid, and became a bullied concubine. In her previous life, she was brutally killed by her impersonated legitimate sister, Shen Yuening. After returning from rebirth, she saw Shen Yuening willing to destroy his innocence in order to please the beggar Sanlang. She immediately watched with cold eyes and bent on revenge. She secretly planned to expose Shen Yuening's scandal, and took advantage of the imperial edict to enter the palace. She was replaced by Shen Yuening and given the title of Concubine Shu on the grounds that she had lost her virginity and was pregnant with a bastard. After entering the palace, she used her strength to drive a wedge between the Zhou family and Shen Yuening. In the end, the Zhou family killed the beggar, and Shen Yuening went crazy and killed her mother. All evildoers will get their retribution.
