Chen Yuhu, a female history university student, accidentally transmigrates into a novel as the tormented and depressed matriarch of a marquis estate. To return to modern times, Chen Yuhu must die of old age in this lifetime. Instead of obsessing over romance with the marquis, she shifts her focus to the estate's affairs, diligently raising the children in the household, fostering harmony among the concubines, and properly managing the concubine brought back by the marquis from the frontier. Amidst various challenges, Chen Yuhu secures her position in the marquis estate and steadily marches toward dying of old age.
