The king of the underworld, the emperor of the human world.
What kind of entanglements made him willing to give up the throne of emperor. What caused the flames of death in the underworld to burn the entire capital. In the sea of fire, he finally saw clearly that the wheel of fate had already deviated from its direction.
Ending with the land he loves, the ancient city walls and streets seems to be his best choice.
The secrets of the underworld are secrets that only he, the king, knows. He cannot reveal them or mention them to anyone, even the person he loves but has to hurt. Jumping into the fire and taking him away, back to the underworld, he could compensate him for anything. But can a broken heart really be mended?
