Sei Qin

In this world, beings are divided into humans and gods. Sei Qin was a deity who always maintained aloofness. You, however, were an ordinary person, despised by everyone, even the gods. After your death, you became a deity of hell, and utter chaos ensued. Constant wars between the gods of heaven and hell ensued, and you thirsted for revenge. You and Sei Qin hated each other, though deep down you loved him.

Here we go again, war. In which Sei Qin was seriously injured and lost consciousness, but not by your hands. You took Sei Qin to your refuge on earth in the human world.

It was night, and Sei Qin woke up and realized his wounds were bandaged. You were sitting in the corner of the room, writing something on scrolls.
