Surviving as the Butler of the Connett Estate

After her treacherous cousin steals her title and fortune, then tries to sell her into marriage, Brienne cuts her hair and disguises herself as a boy to escape. She finds refuge at the Connett Estate—located in a domain that acts as a self-governed city immune to imperial law—working as an assistant butler to the formidable Duke Ulrich Connett. Though feared across the empire as a ruthless war monster, Brienne discovers a surprisingly warm heart underneath his cold exterior—while Ulrich finds himself captivated by his brilliant, fiercely capable new aide.
