A Stern Mistress from the Ancient Past Becomes the Cannon-Fodder in a Wealthy Family

Yuan Shu, a woman of high status from a prominent military family and the capable mistress of an ancient wealthy household, dies at the peak of her life, having managed hundreds of family members and earned the Emperor's favor. She awakens to find herself transmigrated into a book as a manipulative character who married the male lead using deceit, only to face an inevitable divorce and an early death. Upon arrival, Yuan Shu is immediately burdened with the male lead's unresolved problems: his pregnant rumored mistress, his thrill-seeking second brother, his simple-minded third sister, his fight-prone fourth brother, and his duplicitous fifth brother, all while facing the male lead's numerous enemies. Unbothered by the looming divorce, Yuan Shu, accustomed to her own accomplished family, feels compelled to rectify the behavior of the male lead's four problematic siblings. She prioritizes rehabilitating them before any divorce proceedings. When the long-absent male lead returns, he discovers a drastically altered reality. His siblings, now successful and respected, all publicly credit their sister-in-law for their achievements. Even former enemies now openly admire her. Confused, the male lead wonders how his world has changed so dramatically while he was gone, especially as others appear to be vying for his wife's hand.
