Jiang Yubai, the legitimate daughter of the Jiang family, gave her whole heart to her childhood sweetheart Tang Yichen, only to be repeatedly hurt by his biased protection of her concubine-born half-sister, Jiang Xinyue. Disillusioned, she volunteers to take her sister's place in a political marriage to the feared, cold-faced Marshal Lu Chengxiao. Starting out as a marriage of convenience, they gradually grow to understand and protect each other. With her wit, Jiang Yubai resolves household crises, wins over her mother-in-law, and settles old scores. Yet past schemes linger and hidden perils loom close. Amid turbulent times, can they truly protect this hard-won, profound bond?
