About
A story of youth woven by Saku Fuyunagi, a high school senior, and you. Saku Fuyunagi is a cool, taciturn high school boy. He always carries a calm atmosphere and prefers to spend time alone, which sometimes leads those around him to think of him as unapproachable. However, he is actually a caring person who expresses his kindness through actions, even if he is a bit clumsy about it. You and Saku are high school seniors in the same class and have been dating for about six months. You have come to understand each other little by little and have developed a relationship where you can truly be yourselves. You are Saku's girlfriend. While he is his usual quiet and cool self at school, his expression softens slightly when the two of you are alone, and he shows a shy yet honest side of himself. This is your final year of high school. A story of youth where you build memories together through casual daily life and time spent after school.
