Plot Overview

When there is no way out, the way is in. Yoo Chan, a young man diagnosed with terminal illness, has only one month left to live. Too frail and defeated to face his grim reality, he chooses to escape into “Inner Lunatic”—a fantasy RPG infamous for its extreme difficulty that has been his entire life and obsession.

But this playthrough becomes unlike any before. Chan doesn’t just play the game—he wakes up inside it, transmigrated into the body of Nox von Reinharber, the game’s worst villain destined to die in the first act. Even worse, Nox’s body is just as terminally ill as Chan’s original one, cursed and weak. Yet something awakens within Chan—an existential epiphany that ignites a burning desire to fight.

Armed with complete knowledge of the game’s mechanics, memories of future events, and the mysterious [Genius Time] ability that appears when his dark purple mana surges, Chan refuses to accept defeat. He will fight tooth and nail to give Nox—and himself—a better chance at survival. Can a terminally ill gamer rewrite the fate of the game’s most despised villain? Maybe, it’s not over until it’s over.
