The Postman of the Apocalypse

Jeongguk Woo works as a postman in a post-apocalyptic world, where even something as ordinary as delivering mail can be a dangerous job. Yet despite the harsh world around him, Jeongguk has one simple dream—to ride the subway.

When headquarters announces a plan to restore the long-abandoned subway system, Jeongguk eagerly volunteers to take part. Unfortunately, government official Yonghan Cho personally rejects him, claiming that Jeongguk’s record contains none of the dangerous missions required for the job.

Angry at being dismissed, Jeongguk takes on a mission that everyone else considers suicidal: delivering a letter to the AAA, a heavily militarized territory notorious for refusing all mail.

But upon reaching his destination, Jeongguk discovers something he never expected. The letter is addressed to Yonghan Cho’s sisters—and they are desperately asking him to help them escape.

Now Jeongguk faces a choice: follow the rules of a postman and deliver the letter, or break them to save the people who wrote it?
