Kim Hana is reincarnated as Wilhelmina, a fallen noblewoman whose fate takes a turn when she's married off to the wealthy House Layton. But there’s a catch—her husband is already dead, leaving her to become the Dowager Duchess. Younger than her new stepson and his wife, she must navigate the treacherous waters of high society and a daughter-in-law determined to make her life miserable. Will she find a way to remedy this family drama or be unfairly painted as the monster-in-law she’s not?
