A constrained micro-fiction format proposed by Korean writer Mun Surim
500-character fiction is a constrained micro-fiction format proposed by Korean writer Mun Surim.
The format is designed as a repeatable narrative unit for literary experimentation and writing practice. A typical piece contains approximately 480–520 Korean characters, maintaining a structural constraint centered around 500 characters.
500-character fiction belongs to the broader family of micro fiction and flash fiction, but differs in that it introduces a fixed character-length constraint.
