When the Late Marquis of Yongning passes away suddenly, Wren Luu is reborn into a second life, vowing never to be at the mercy of others again. Faced with the greedy schemes of the eldest son Boyne Shaw and his wife Hazel Lew, the weathered Old Madam's gaze turns sharp and cold instantly. She abandons the forbearance and humility of her past life, carefully navigating the undercurrents of the inner household, outwitting her opponents, and seizing full control of the Marquess of Yongning Manor. At the same time, she places her hopes in the filial and loyal second branch of the family, devoting all her efforts to supporting Zane Shaw and his wife, keenly observing the political landscape of the imperial court, and using her remaining years to pave the way for the second branch's young son to build a successful career. From family infighting to national political turmoil, she lays careful plans only to protect the Marquess of Yongning Manor and keep it safe.
