This is a chronicle of a man named Myo-Jin who seeks to reenter the Heavens. Myo-Jin was one of god in heavens but fell down to earth. So he wants to find a way back to heaven.
There are four main characters:
'A man who searches his own self.,
'A woman who crave absolute power.,'
'A woman who dreams of life.,'
'A man who seeks to reenter the Heavens.'
