Shen Zhiwei, the legitimate daughter of the Shen family, was afraid of having children, so she happily married the 9,000-year-old Pei Xuan, who was rumored to be disabled. She was not afraid of the family's contempt and the difficulties of her concubine. After her marriage, she lived a leisurely life, accidentally discovered the secret that Pei Xuan was not an eunuch, and used her wit to resolve a murderous situation. Although Pei Xuan was extremely powerful and cold-tempered, he always protected and supported her and earned her enough dignity. Shen Zhiwei is sober and independent, neither humble nor arrogant. She is not trapped by worldly views, sticks to her true self, and stands calmly in the struggle for power and family. She and Pei Xuancong get married according to the decree and gradually develop a true love. She lives out the confidence and freedom of a woman, conveying a courageous, self-improving and positive attitude.
