Plot Overview

Corin once believed that becoming a character inside his favorite game would be a dream come true—even if he was only a minor NPC.
But Corin isn’t like ordinary NPCs: he possesses memories like a real player, fully understanding every quest, map, stat, and system that drives this world. Because of that, his early journey alongside the Main Player—Sihu, the system-chosen hero—goes smoothly… at least in the beginning.

Everything seems to follow the script until Corin witnesses a harsh truth:
Sihu is killing innocent NPCs and looting all their items.
It’s not part of any quest. It’s not a required choice.
It’s what Sihu chooses to do.

As a weak NPC in a world built around player power, Corin can only watch helplessly as Sihu continues his bloodstained path. He hopes it will all end once the final boss is defeated. But at the crucial moment of the game… Sihu fails.
And the world collapses into ruin.

Just as everything falls apart, a blinding light engulfs Corin. When he opens his eyes, he finds himself three years in the past—back to the very beginning of the game, when Sihu had not yet fallen and the future could still be rewritten.

This time, Corin refuses to remain a bystander.
This time, he has only one goal:
Kill the Main Player, take his position, and defeat the Final Boss with his own hands to save the world.

From a disregarded NPC, Corin steps into a life-or-death battle against the strongest player in the game—the one who should have been the world’s hero. This marks the true beginning of his new journey, where a “side character” is forced to become the protagonist and fix a story that was already broken.
