Cui Dai, the child bride, was sent to Xuanque Palace due to a marriage contract. She was originally thought to be a chess piece for anyone to manipulate, but she used her extraordinary strategies to repeatedly break the conspiracy in the secret battles in the palace. Xiao Yan, the cold-faced emperor, went from being used to falling in love with Cui Dai, but he was defeated by Cui Dai's "anti-general army" time and time again. In the end, he overturned the old system for her and performed the ritual of "betrothal of a man to a woman" with the dignity of an emperor, achieving a strong love of two-way redemption. The whole drama is full of strong and exciting points: slapping the sister-in-law in the face, outsmarting the powerful ministers, counterattacking and killing the hidden stakes, and the emperor chasing his wife. The feeling of excitement runs throughout.
