leo who born into a family of 2 and raised by love but unfortunately when he was 12 he lost his parents to a car accident and he have to survive without parents, and forced to endure a life of struggle. He dies young at eighteen by trying to save someone —only to awaken in the world of a novel he once read.

But he is not reborn as a hero or a chosen one. He becomes an extra—an insignificant existence never meant to matter in the grand scheme of things.

Unlike others, Gray knows fragments of the future. Not a destiny to follow, not a story to obey—but knowledge of the dangers this world will face.

Yet he rejects the idea of following any “main storyline.”

He refuses to become part of anyone’s destiny. He refuses to chase power for ambition or glory. His only desire is simple: to live in peace, protect his new family, and exist freely without bowing to anyone.

However, in this world, peace is a luxury rarely allowed.

Alien beasts roam the land, and danger lurks not only in the wild but also among humans themselves. Those who threaten the people he cares about soon discover that Gray is not just an observer of fate—but a force that responds when pushed.

He does not seek war. He does not seek revenge for the world’s story.

But when harm comes to his loved ones, he becomes something far more dangerous than any beast.

As survival and violence shape the world around him, Gray walks a path defined by one truth:

He may be an extra in the story… but he will never be powerless in it.
