Twelve years after the demolition of the old city, archivist Lin Qiuyuan saw a building No. 14 That was neither on the map nor in the archives in a night photo.
The person who took the photo is being forgotten one by one by the access control, the salary list, and the people around him; his father, who has been missing for twelve years, left a sentence on the back of the photo: The house number is not for the house.
As the investigation continued, Lin Qiuyuan discovered that every promise made publicly but unfulfilled by the city would become a "debt of wish." Some people use it to save people, some people transfer it to unknown people, and some people want the whole city to forget the cost.
She has no system and is not the chosen one. The only thing she's good at is writing the deleted name back in - then signing her own name and bearing the consequences.
