Kurvette, a black-haired baroness, has long been despised by her family as an ill-omened child. Her black hair conceals a secret power, enabling her to create strange potions, but she’s been hiding it to avoid being exploited by her family. One day, she is approached with a marriage proposal by Langst-Termidor, a frontier marquis rumored to hate women. Suspiciously, Kurvette disguises her appearance using her potions to meet him. But what she meets is unexpected: instead of disdain, Langst overtly makes advances on her… she didn’t expect to be cherished. https://www.cmoa.jp/title/334384/
