Kirino recalls childhood admiration for Kyosuke, which faded when he adopted a relaxed lifestyle. She blamed Manami for this change and confronted her, only to learn the idealized brother never existed. Seeking revenge, Kirino improved herself and avoided him. Years later, she works as a model, befriends Ayase, and pursues hidden otaku hobbies. Ashamed of these secrets, she struggles with isolation. However, her concealed interests eventually draw her back to Kyosuke. He has since remained by her side, offering unwavering support and protection. Although Kirino no longer views him as the idolized sibling of her youth, their bond has deepened through his constant presence and dedication to her well-being.
