Nathan Kim is ripped from his world and dropped into another, trapped inside someone else’s body. He inherits that man's bloody reputation and a mercenary band who call him Boss. To survive, he must bluff his way through dungeon crawls, monster hunts, and dangerous politics while under the scrutiny of Kieran, a guild commander who has openly claimed to seek revenge on the man Nathan is now forced to impersonate.

Powerless, without a tutorial, and with no clear path home, Nathan must navigate a world of magic, guild intrigue, corruption, and rising war. Every step he takes is shaped by the danger of being seen as someone he is not—and by the enemies he never meant to inherit.

A BL-flavored fantasy isekai with a body-swap twist and a slow-burn romantic subplot. Adventure, danger, identity conflict, emotional depth, and worldbuilding drive the story, with romantic development unfolding gradually and naturally over time.

Not a romance-first or smut-focused story.
