During the summer vacation after my third year of junior high school, I sat sideways at my desk and glanced at the brightly colored graduation photos on the bookshelf. I seemed to still smell the sunny sky when I took the photos in May... A similar sound of cicadas sounded outside the window, but it was no longer the same place. The past is over, and the slender figures in the memories overlap and intersect, tracing the outline of the scorching gaze of the past three years - we were classmates, and you were by my side.
