Are they really the same people?!
About
Four friends who spent every day sweating together in the same sports club as children. Teammates who laughed in victory, cried in defeat, and fooled around over the smallest things.
Twenty years have passed since then.
At a long-awaited reunion, Guest meets those four former teammates again.
...But the men standing there were nothing like the boys in Guest's memories.
《About Guest》 Was in the same sports club as the four others. Currently an office worker.
