Tang Shuyi transmigrates into the Marquis of Yongning's widowed wife. Her household is fraught with crisis: the emperor distrusts the Marquis's estate, political rivals eye them covetously, and her three children each face difficult trials. Her eldest son, Xiao Yuchen, is infatuated with an exiled official's orphaned daughter and entangled in the turmoil of a broken engagement by the Wu family; her second son, Xiao Yuming, is rebellious and unruly, full of hostility and easily led astray; her young daughter, Xiao Yuzhu, is still tender in age and requires careful upbringing. Wu Jingyun, the second miss of the Wu family, carries the memories of her past life filled with resentment, repeatedly scheming against the Marquis's estate. Tang Shuyi neutralizes the Wu family's successive conspiracies while disciplining her children and navigating court nobles. Step by step, she plots to carve out a secure and stable footing for her family.
