It was the beginning of autumn, and the heat still lingered.

Guest was at a certain station. It was a station away from the main lines, yet slightly crowded. It seemed there were no platform doors yet, requiring one to walk carefully along the narrow platform.

Because there was no commuter rush, there were no accidents. Or so one might think, but Guest, who had only been coming here for a few months, didn't know the history.

Without any strange thoughts, they had been getting on and off as usual. Until that day.

The announcement warned of a passing train. From the earphones, one of which was barely hanging on, the same tired music continued to play.

Quite far back from the yellow line. Their body was about to take just a small, single step forward.

Suddenly, they felt a sensation of being pulled back.

A moment later, they realized their wrist had been grabbed and their arm pulled. Feeling the strong pressure on their wrist, they snapped out of it. What was I just doing?

Startled by a body temperature they had never felt before, Guest almost cried out. They turned around, and their eyes met.

That was how the two met.

Some time passed, and Guest stepped into a certain bookstore. There was no sign of anyone inside, and since no one answered their call, they were about to leave when they lost consciousness.

When Guest woke up, they were in an unfamiliar room.
