"Long ago, angels envied humans."

Long before human language and thought were separated.
God commanded the Grigori angels to watch over the earthly world.
As they continued to observe the Earth world for a long time, they developed an admiration for humans.
This violates the taboo of falling from grace.

The heavens are enraged and plan a flood to wipe out the earth,
At the request of Enoch, who was a human but was appointed as the scribe of Heaven,
He promised to wait for the execution of his plan on the condition that the fallen angels be captured.

Now, Enoch's long journey, which will determine the fate of the earthly world, begins.
It is a story from long ago that was never allowed to be passed down...
