Su Wanyue, a modern independent woman, traveled through time and became the legitimate daughter of the general's palace and the wife of General Dingbei. She died early due to dystocia. After she was reborn with modern thoughts, she discovered that her husband Huo Tingzhao brought back his concubine when he returned from the border. Su Wanyue was angry and broke up. In order to obtain the emperor's order, Su Wanyue frequently went in and out of the palace, and unexpectedly made the emperor Xiao Chengyu laugh with her sharp and forthright demeanor and out-of-the-box thinking. The two went from fighting each other to developing a secret love. During this period, the green tea concubine pretended to be weak, the jealous concubine made a stumbling block, and the yandere former noble concubine set up a trap. Su Wanyue was all slapped in the face in the way of "repaying him with kindness". In the end, Xiao Chengyu ignored the objections of the courtiers and included him in the harem. From "troublemaker" to "darling", he staged a sweet and spicy palace story of two-way secret love.
