Bai Xiyue, the second legitimate daughter of the General's Mansion, is reborn and stumbles upon the secret affair between her eldest sister and the Third Prince. She proactively offers to switch brides to marry Prince Gong, Xie Jingyao. Entering the palace, she reclaims her imperial gold token dowry and suppresses her stepmother. Once in the prince's manor, she sees through Xie Jingyao's feigned coma to uncover that he is secretly investigating a case, and the two form an alliance, progressing from partners to life-and-death companions. Battling both in the household and the imperial court, she exposes her stepmother's treason, the Third Prince's crimes, and delves into the past tragedy that claimed the lives of nine of her father and brothers, tracing it back to the Imperial Noble Consort who lurked as a Northern Mang spy for seventeen years. At the Crown Prince Ceremony, she protects the sovereign, unmasks the culprit, vindicates the Bai family, and walks hand in hand with Xie Jingyao into old age.
