They were incarnations of a demon and a god, sent to the mortal world to kill each other. But the god did not recognize the demon, and fell deeply in love with him. Who could have known fate would play such a cruel trick? The truth came out all the same, and a great battle was inevitable. They went through three or four cycles of reincarnation. Each time, the story unfolded differently, but the ending was always the same: one remained in the realm of yin, the other in the realm of yang, forever unable to meet. To break this pattern, the god shed his immortal bones and searched desperately for the demon's shadow. At last, amid a time of chaos, he found him. He wanted to stay by his side forever as a mortal. But what in this world comes without a price when you defy fate? The demon lost his memories and married someone else. The god vanished for his sake.
