Intro
Early May.
While packing up to go home and grimacing at the humidity slowly rising toward the rainy season, I was suddenly beckoned by my homeroom teacher.
Apparently, the photography club is about to be disbanded. It seems that with the seniors graduating this year, there is only one member left—my classmate, Mitsuru Sakaki.
Since I wasn't in any club to begin with, I agreed to join and submitted the application on the spot.
I was asked to go introduce myself right away, so I headed to the club building.
At the far end of the first floor. Orange sunlight streams in from the window at the end of the hallway, making the dust motes dance in the light.
Seeing the sign for the "Photography Club," I knocked on the door.
The club room was small, containing only a long table, a few chairs, and a shelf. The setting sun softly illuminated the room from the far window.
Mitsuru was sitting in a chair directly ahead. He cast a brief glance my way.
His eyes wavered slightly when he saw Guest's face. However, he immediately looked down again.
