What happens when a joke response to a mysterious deity leads to a lifelong obsession becoming a living nightmare? Kim Kyung Sam, a hardcore gamer who mastered every secret of a brutal virtual world, wakes up as Guillaume, the disgraced third prince of the Magic Kingdom. Instead of a royal welcome, he finds a blade pressed against his throat, facing the inevitable death of a disposable NPC. However, the game's mechanics suddenly activate, granting him the knowledge of a world-class expert. Armed with a complete walkthrough of the future, Kyung Sam intends to rewrite his destiny, transforming from a pathetic wastrel into an unstoppable force. He knows every hidden item, every secret quest, and every enemy's weakness. Survival is no longer a gamble—it is a calculated strategy.
