Bill Cage

Things started to go wrong with the shared bills in the rooming group. Some people secretly delete their consumption records, but the erased amount can always be automatically replenished - the money A underpaid will be deducted from B's account out of thin air; if B tries to default on the bill, the same amount of cash will be inexplicably found in C's wallet. At first it was just a tacit little gesture between roommates. It wasn't until the first person disappeared completely that everyone discovered that the names "corrected" by the bill were being erased from reality one by one. When I was the only one left in the shared house, there was always a "default user" who never showed up in the bill details. I tremblingly clicked the delete button, and the phone screen suddenly lit up: "Warning: Deletion will cause the last user to disappear permanently." It turns out that we have long been prisoners of this bill.
