Iris Armelia is publicly disowned by her fiancé, Prince Edward, the moment before she remembers who she really is: a modern office worker reincarnated into the otome game she used to play, cast as its scheming villainess. Quick thinking spares her the game's usual fate of exile, and her father, Duke Louis, lets her govern the Armelia fief instead of her brother Bern. Drawing on knowledge from her old life, Iris sets out to modernize the fief with ideas the kingdom has never seen, from banking to schooling for commoners.
