In order to be immortal and wait for the reincarnation of his lover, the Yin-Yang Demon Lord has practiced magic skills for thousands of years to be ruthless and desperate. However, just when he was about to completely bury his infatuation and obsession, he met a girl in red, carrying a wisp of his lover's soul. He was not sure that he no longer had the seven emotions and six desires of a normal human being, but he couldn't help pretending to be a rogue knight and followed him to find out...
Although the girl carries the soul of his previous lover, she is not the reincarnation of his previous lover. The girl grew up on the Holy Mountain and was the perfect candidate to succeed the Holy Girl. However, just to catch a glimpse of the person in her dream, she betrayed her master and fled down the mountain...
Is love caused by coincidence a mistake? Is there any medicine in the antidote to love that is not available to love?
Intention: The so-called obsession is all illusion in the end
