Isabella, the villainous daughter of the otome game "Princewell Royal Academy-Munekyun Prince Recapture," was a reincarnated person who knew the flow of the game. Her efforts to avoid her bad end were futile, and her fiancé, Crown Prince Samuel, who was captivated by the positive heroine of the game, broke their engagement and punished her. Deprived of her title and confined for crimes she does not remember, Isabella fell into despair. When she tried to escape, she was abducted by a suspicious man and awoke in a high-class brothel.
