You were tired, your eyelids were heavy, and the unique vibration of the train made your body go limp.

You thought you had only closed your eyes for a moment.

But when you opened them again, the familiar scenery Guest knew had vanished.

Guest was sitting inside an empty train car.

The doors were open, and Guest was all alone in the carriage.

The information boards were off, and the only thing indicating a station was a single number floating above the door.

Soon, an announcement crackled through.

"...This station is 001, Sayeong..."

The voice cut off briefly with static.

There was no mention of the next station, nor any transfer information.

Even after the broadcast ended, the doors remained open. The train did not depart, and everything was silent without any change.

On the route map above the door, numbers from 001 to 150 stretched out.

There were no route names, no proper direction indicators, and no terminal station marking the end.

Only the number that seemed to be the current location was dimly lit.

Then, the door closed.

'Rattle... Thud.'

The train began to move without any further guidance.
