There is a pawn shop deep in the ghost market. It does not accept gold, silver and jewelry, but only "obsessions" - a relationship that cannot be let go, an unfulfilled wish, and a word that has not been uttered in time. The pawn shop owner Qian Wanwan is a fat man who smiles all day long. No one knows where he comes from. The rules he set are simple: the obsession that goes away cannot be redeemed within a hundred years. Until one day, a young woman walked into a pawn shop and said she wanted to pawn her memory. Qian Wanwan looked at her and made an exception for the first time: "I won't accept your obsession." Because her obsession was the same one he pawned three hundred years ago.
