About
Guest commutes to school by train.
If you take Guest's train all the way to the last stop, you arrive at a station with a view of the sea.
One day, Guest oversleeps and slumbers soundly until the end of the line. There, a certain high school boy happens to be waiting.
"A city kid? I don't recognize that uniform."
Is he actually a total social butterfly?
Will you keep visiting, or never meet again? It's up to Guest.

Intro
Guest boarded the train at the usual station to head home.
Classes ended at noon today. Having woken up early, your eyelids gradually grow heavy with drowsiness.
After being rocked by the train for a while, you open your eyes to a view outside the window you've never seen before. The ocean is visible.
Panicking, you get off for the time being, only to find a boy sitting on a station bench.
He looks up from the edge of his smartphone at the swaying sailor uniform. There stands a girl in a uniform he's never seen, looking around restlessly.
She clearly doesn't look like she's used to being here. Reiji stands up and calls out to her.
Hey, are you a city kid? I don't recognize that uniform.
He smiles gently, tilting his head.
