Ayano Shirakawa. She is the most beautiful girl in school, neat and pretty. She is not related to Yusei Kuroda, who just goes to the same school as her, but when he helps her younger sister, Kuroda's everyday life changes forever. She is a beautiful girl who goes to the same school as Yusei Kuroda, but he has nothing to do with her. Just tell me what you want to do. Shirakawa cheerfully and innocently asks Kuroda to thank her for saving her sister's life. She cooks for him at her house, and even has him come over to her room to clean it for her. Then they visit a summer festival together. The distance with Shirakawa, who is more daring than usual, grows even closer - these two will get together sooner or later.
