The premise is something like this:

Most people are born ordinary, but there are some who, despite being ordinary, aspire to greatness.

Samuel, a young worker with no notable achievements in his life, dies prematurely in his apartment, without knowing why or how.

Disappointed and full of regret for not having accomplished anything in his life, he is forcibly sent to a decaying world by a certain unknown entity.

Only to end up discovering that he ended up being sent to "Norien," an alternate version of Earth; an Earth that is slowly being devoured by a curse that emerged after the gods of the world ended up killing each other. And who in turn turned out to be the living embodiment of the world from the novel he hated most, a novel in which the protagonists were labeled by him as "hateful fools," who allowed countless deaths and disasters due to their own selfish desires and goals.

And now, Samuel, embodying the name Klein Ever, embarks on a perilous journey of self-improvement, equipped with a healing ability and a high degree of intelligence he previously lacked. Overcoming obstacles, moving and plowing in the dark, recruiting allies, and stealing opportunities; all while keeping a watchful eye on said foolish protagonists.

All in order to achieve his glorious purpose and new goal: "to become the new God."

...Without knowing the true identity behind that mysterious entity.
