In her past life, Shen Zhaoning, the concubine-born daughter of the Shen manor, was betrothed to Prince Jing because of a hairpin, and died in resentment after being harmed by her legitimate sister. Reborn on the day of their first encounter, she refused the hairpin, and her cousin Lu Qingyi took it. In a fit of anger, her legitimate sister injured Qingyi's face, thereby shattering her own dream of becoming a princess consort. When the imperial decree descended once more, she was betrothed all the same. In this lifetime, she is no longer naive; retreating to advance, she moves step by step with caution, securing the Empress Dowager's backing, thwarting the entry of a secondary consort into the manor, and conceiving an heir. When a fire broke out in the prince's manor, resulting in the prince's face being disfigured, she used the Buddhist service at Fahua Temple to publicly expose her legitimate sister's past deeds—the debts of the past life shall be settled one by one in this lifetime.
