This is about the peerless love between the King of Blood and the God of Hell.
There are only three colors in this world, the white of heaven, the black of hell, and the red of earth. Throwing between these three colors is a thousand years of love, a thousand years of attachment, a thousand years of sin, and a thousand years of persistence...
And they are only qualified to watch, watching everything turn into ashes again and disappear forever.
In the dusk of love, what is left?
Is it hate or no regrets?
