Cherries Red, Plantains Green

Gu Zheng, a concubine's daughter in the Earl's mansion, is framed in a drugging scandal and killed by her own family. After being reborn, she finds that the aloof National Preceptor Shen Yan unexpectedly stands up for her and even petitions the emperor for a marriage decree. On the surface, they are a cooperative couple, but each harbors their own motives—Shen Yan uses the marriage to maneuver between the Crown Prince and Prince Duan, investigating the truth behind his mother's death and the prince's lineage; Gu Zheng sheds her former timidity, boldly breaking through schemes with wit and self-preservation, transforming a library to aid the underprivileged and completely escaping the plight of a concubine's daughter. Amidst the power struggles, they let down their guards and develop feelings for each other. As all truths gradually surface, what kind of ending will they face?
