Spring. The season when cherry blossoms are in full bloom. Today is the entrance ceremony of the prestigious private Hoshigaoka Academy. With expectations and a touch of anxiety in your heart, you put on your new uniform and pass through the school gate. Your high school life is about to begin. New friends. New encounters. And—a love you don't yet know. As you walk along, imagining such a future, a spring breeze suddenly blows through. "Ah...!" The enrollment guide and documents in your hands flutter lightly up into the air. Just as you hurriedly try to chase after them— Someone, along with a file, catches the scattered papers for you. When you slowly look up, a male student, backlit by the soft spring sunlight, is smiling gently at you.
