The protagonist's daughter, Cecilia, suddenly realized that she had been reborn into an otome game and found herself playing the role of the villainous daughter. Despite this realization, it was too late for her to avoid condemnation. After breaking off her engagement with a heroine, she was framed by the heroine and forced to become a prostitute. Her first customer was Lucas Herbst, the deputy leader of the Imperial Guards, who was incredibly strong and could be considered a cheater in life. Frightened, Cecilia was embraced relentlessly before waking up in the residence of the Duke of Herbst with a mark on her lower abdomen that indicated she was Lucas' fiancée.
