When An Ci woke up, she saw an old, weather-beaten bus ahead of her, its bodywork giving it a mysterious air. On the window outside, someone had written in an unknown liquid: "Passengers, please take your seats. During the journey, do not walk around or disturb the other passengers." The words filled An Ci with unease and dread.
She looked around and realized this seemed to be an abandoned bus station, with the bus sitting there all alone. She hesitated, but eventually decided to climb aboard and find out what was going on.
Once inside, An Ci saw a name tag on every seat, as though each one had been reserved for a particular passenger. Passengers began to board one after another. They remained silent, each taking a seat as if pulled there by some unseen force.
The passenger beside her was very friendly and liked helping people find things, but favors had to be repaid.
In the dark world, nothing can be trusted except yourself. If you have companions, can you truly give them your trust? Are they worth it?
