Memory Rental Station

The residents of the Forgotten City wake up every day and forget part of their memories of the previous day. The "Memory Rental Station" is the only place where memories can be stored and traded - you can rent other people's happy memories to relieve pain, and you can also sell your own secret memories in exchange for survival resources. However, memories can become distorted after being traded many times, and can even create "memory shadows" that devour people's consciousness.
