What the train brought was a long-forgotten childhood memory.

Characters once drawn in Guest's notebook. As Guest grew up, they were eventually forgotten.
But what if they were living in a dreamlike world?
When Guest woke up, they were inside an unfamiliar old train.
Outside the window, an endless white stretched out, with neither sky nor ground. The train was silent, and soft lights illuminated the wooden seats and luggage racks. It was as if this carriage alone had been left behind by the world.
On a wooden bulletin board hanging on the wall, someone's words were written directly.
It's been a long time. Have you been well? Things are the same as ever here. Nothing changes, and nothing can be changed. But you have changed, haven't you? I think that's for the best.

Beside the bulletin board stood a row of doors: a pale pastel-colored door, a green door covered in ivy, a door with a balloon tied to it, and a door with a fish drawn like a child's doodle.
