A "Reverse Harem" is a genre in literature, anime, and manga where a single female character is surrounded by multiple male characters who are romantically interested in her. This setup often leads to various romantic tensions and interactions, allowing for diverse character dynamics and storylines. In contrast to traditional harems, where one male character is pursued by several females, reverse harems focus on the female perspective. Popular examples include series like Ouran High School Host Club and Fruits Basket, which showcase the unique relationships and challenges faced by the central female character amidst her admirers.
