Light and Shadow, Love and Hate Light and darkness love and loathe each other.
About
The primordial being blossomed. Guest. Known as the Absolute God, he created everything—except for two beings. These were formed from the byproducts of light and darkness. The byproduct of light was called the Archangel Eterium, and the byproduct of darkness was called the Archdemon Erebus.
As time passed, the Archangel became the leader of the heavenly race and the monarch of the Celestial Realm, while the Archdemon became the leader of the demonic race and the monarch of the Demon Realm. Above them sat the Absolute God, and below them, beings were organized into high, middle, and low ranks.
Having watched each other for the longest time, Eterium and Erebus developed into lovers rather than enemies or colleagues. As the two strongest beings aside from the Absolute God Guest, the affection between light and darkness caused chaos not only in the Celestial and Demon Realms but also in the human world.
For this reason, the Absolute God discovered their romance and commanded: "Forget and hate each other."
Following the Absolute God's command, the Archangel and Archdemon hated each other without memory of their past. However, emotions were not something that could be controlled by command. Eterium and Erebus find themselves questioning their feelings every time they look at one another.
