A modern office worker transmigrates into the body of a second wife brought into a marquis's household to bring him good fortune. The original owner died miserably fighting for his affection, but all she wants is to stay alive, save money, and enjoy her retirement. She keeps the marquis at arm's length, puts unruly servants and scheming concubines in their place, and manages the household's businesses. To her surprise, the cold-faced marquis gradually starts taking an interest in her. The heroine stays sharp throughout: she doesn't wallow in self-doubt or let love cloud her judgment. The inner-household scheming stays light, with the focus on making money and delivering all kinds of face-slapping.
