Nathan Kim had it all: height, looks, charm — and the kind of body that made everyone assume he was always in control. Back in Seoul for a family visit, he slips into the polished “pretty boy” role with ease. But one night, a shimmer tears open in a back alley, and Nathan is dragged into another world.

He wakes in the scarred body of Mason, a ruthless warrior-mage feared by all. Surrounded by blood and hailed as “Boss,” Nathan realizes with horror: he hasn’t been dropped into the hero’s role. He’s the villain.

Now, with no powers, no tutorial, and no way home, he must bluff his way through Mason’s brutal legacy, mercenaries, dungeons, and guild politics. Worse still is Kieran — the storm-eyed commander who despises Mason most… and tempts Nathan more with every clash.
