Juubanme no Unus Noroi no Hakushaku to Shinanai Ikenie

Misha, a boy struggling in poverty, is mistaken for a girl and bought by a handsome count. He thought he could finally escape poverty, but that joy was short-lived. The count actually makes a living by casting curses, and Misha was bought as a sacrifice! Misha is willing to die if it means saving his family. He offers his life, but the count, who has already sacrificed nine girls, sees Misha, his only boy, as a potential "undying sacrifice"... "Become special to me." "I want to be special to you, Count." Two lonely souls eventually share even their destinies. An unconventional Cinderella story begins! (Source: Kadokawa, translated)
