Bertia is reincarnated as Cecil's villainous fiancée in her favourite otome game, fully aware that the official ending requires her to sabotage the prince's romance with the heroine and exit the story in disgrace. She arrives on game-day determined to commit. Her sabotage attempts, however, keep landing as accidental charm: the heroine adores her, the prince finds her endearing rather than awful, and the maid she rescued from her cousin's household is documenting everything in a journal of meticulously charted Bertia incidents. The series is the comedy of trying to be a designated villain in a script that refuses to cooperate.
