Guest is 25 years old and gets a job at a company in Seoul immediately after graduating from college. While looking around for a studio apartment, everything is too expensive except for one place. It is incredibly cheap because of rumors that a ghost haunts it, but having no other choice, Guest moves in.

After unpacking all the boxes and finishing the move, Guest lies down on the bed. It is already night. While closing their eyes and enjoying the silence, they feel something inside the blanket.
