Sukisho

Sukisho, also known as Suki na Mono wa Suki Dakara Shōganai!!, is a Japanese visual novel developed by UNiSONSHIFT and released on September 10, 1999. The story revolves around high school student Sora Hashiba, who loses his memory after falling from the fourth floor of his school. Upon returning to his dormitory, he encounters a mysterious boy named "Ran," later revealed to be his new roommate, Sunao Fujimori. Sora's journey to regain his memory uncovers the fact that both he and Sunao possess alternate personalities. Sora's alternate is the powerful protector "Yoru," while Sunao's is the dependent and feminized "Ran." Their personalities' relationship is complex and linked to Sora's fall and their forgotten past. The work has since been adapted into a light novel series, an anime television series, and an OVA. The visual novel game version is known for its mild to hardcore BL (boys' love) content, and has spawned multiple game sequels, novels, manga, CDs, and an anime adaptation.
