Among the Shopkeepers

A pawn shop in a parallel world. Different people come here every day to pawn and pick up things. One is a middle-aged man who has traveled to this world a long time ago and inherited a pawnshop. The owner of the pawnshop is extremely lazy. One is a sixteen-year-old boy with a simple mind who has just traveled to this world and was taken in by a "kind-hearted" shop owner to work as a handyman in the shop. What weird things will they encounter in this parallel world...
