Shen Qingge, the daughter of a general, married the fourth prince Xie Min as a secondary consort due to her father's lifesaving grace. Xie Min was already betrothed to Ruyue, and initially only intended to give her peace and prosperity. As they spent time together, Shen Qingge's intelligence, martial arts, and kindness touched Xie Min. Suffering from cold poison, Shen Qingge silently protected him multiple times and even risked her life to save him, causing them to cross boundaries. Xie Min fell for Shen Qingge, but could not let go of his promise to Ruyue, leaving him in inner torment. Court disturbances, tribal conflicts of the Ulan and Yan tribes, along with the Empress's interference, caused endless misunderstandings between the two, leading the heroine to lose heart and ask for a separation, initiating an entangled story of tormented love and chasing the wife.
