Jaehwan was a demigod son of Zeus. Powerful, blessed with incredible power that he didn't know what to do with, respected by the wind and the sky as the most talented demigod ever seen for a thousand years - he had everything, including others' expectations.

Wonshik was a demigod son of Hades. Secreted away in the Underworld since birth, nobody knew him and he knew nobody. Tucked away in his corner, he grew almost as strong as Jaehwan, the star of the heavens; but no one saw him, and he preferred to keep it that way.

Their paths could never cross... right?
