Cecile lost her entire inheritance to her cousin as a result of not being a male heir. Three men then begin to appear in her life: the Duke of Marmontel, who has obtained wealth and power as a branch member of the royal family; the young and handsome Count Rohan, who has come to France from England; and Azrael, the demon who covets her soul. The quick-witted Cecile, with her ability to grasp others' desires, thus begins to use the three men to get what she wants. And somewhere along the way, confusing Cecile is memories of her previous life, memories that she slowly recovers... Original Webtoon: Daum, KakaoPage Official Translations: Japanese, S.Chinese, Thai
