One day, a demon falls from the sky in front of college student Natsume! Nene, a new succubus (♂) who came to the human world in search of his "destined person", decides to stay in Natsume's room until his injuries heal. Speaking of food for a succubus, it's human semen! ...However, Nene is a virgin who has never had sex. "I think it's gross, but I know how to do it...''
Good-natured college student x naive and natural virgin succubus (♂). Pure love and spoiled cohabitation BL about finding your “destined person”!
