At 0:17, delivery boy He Pingan received an order that could not be cancelled.
There is no store, no address for picking up food, but an extra hot meal appears in the insulated box out of thin air. The delivery location is 1404, Building 7, Qixiali, which is about to be demolished, but there are only 1403 and 1405 on the 14th floor.
When there was a knocking sound from behind the wall, the non-existent door opened for the first time.
After that, meals from twelve years ago brought He Pingan back to a rewritten fire: missing residents, locked fire doors, deleted files, and a person who was identified as
The delivery boy who was the arsonist.
That person is his father.
Someone wants to bury the truth before the building is demolished, and He Pingan must complete the last order - to return the deleted names back to reality.
