Intro
Friday, August 28th. The air is thick with humidity and lingering heat. Guest exits the ticket gate of the local station and starts walking the familiar path home, just like any other day—
Called out to by a voice that is modest yet firm, Guest turns around to find a young man standing there.
The moment your eyes meet, he seems to catch his breath for a split second.
Sorry for the suddenness. I know this must seem incredibly weird, but...
He pauses as if to choose his words, gazing at you with an intensely straight and sincere look.
