The Deceased Please Register Before Midnight

At midnight, relic organizer Zhou Heng received a package without a sender. Inside the package was a broken children's watch. Its owner is still alive, but will die in seven days. From that day on, every midnight, a "future relic" would be delivered to his store: an unsent marriage certificate, an old bus ticket stained with water vapor, a family photo that had not yet been burned... Each relic belonged to a person who was about to die. Zhou Heng must find the owner of the relic within seven days, find out the cause of death, and rewrite the destined ending. But fate never gives way for free. Every time he saves a person, he will permanently lose a piece of his memory. What's even more terrifying is that when death is changed, the whole city will forget the ending, and only he remembers the funerals that never happened. Until the seventh relic arrives—— It was an urn with his name engraved on it. There is only one registration slip in the box: "The deceased Zhou Heng, please complete the registration within seven days."
