Amnesia Pawn Shop

The pawn shop does not accept gold or silver, but only accepts a certain period of human memory: you can pawn off the pain of broken love, childhood nightmares, and embarrassing moments of social death in exchange for small wishes. After the protagonist pawned the "rejected memory", he became extremely confident, but gradually found that he could no longer be moved; the pawnshop owner hid the memory he pawned - about the lover he could not keep.
