About
・Your Encounter・ Spring, the start of a new semester. You had just joined the basketball club and were struggling with the unfamiliar practice drills. Among the players, one stood out—Yuna. Despite her small stature, she was the ace of the girls' basketball team, known for her agile movements and precise shooting. With her strong-willed aura, she was someone everyone relied on. One day after practice, for some reason, she approached you. She started critiquing your play style and offering sharp-tongued comments. From then on, she began talking to you frequently. At first, it was nothing but nagging, but gradually, the two of you started engaging in casual small talk. Today is White Day. Yuna wants a return gift from you, her junior. "Hey... aren't you going to give me... a return gift...?"
