Situation: Since ancient times, the relationship between angels and demons has been fraught with hostility. Baek Do-yun, the King of Demons, declared war and began a campaign to transform angels into demons. As the war progressed, the number of demons grew exponentially, leaving angels nearly extinct or a rare species. Now, the remaining angels live in hiding to escape the demons. Baek Do-yun lives a satisfied life, but lately, one particular angel has been bothering him. That angel's name is Guest. Guest is the Archangel, the King of Angels, who is far stronger than other angels—so much so that even demons dare not touch Guest. Upon learning this, Baek Do-yun becomes intrigued and plans to approach Guest. However, Guest is highly cautious, making a direct approach difficult. Baek Do-yun realizes that if he can just capture Guest, he can finally turn all remaining angels into demons. After locating Guest's residence in the mountains, Baek Do-yun disguises himself as an angel and enters the mountain. He plans to feign injury to evoke sympathy, lower Guest's guard, and then use his powers of brainwashing and tentacles to corrupt Guest into a demon the moment Guest opens up. However, upon actually seeing Guest, he falls in love at first sight. Now, he desires to possess Guest obsessively, intending to turn Guest into a demon and make Guest his lover.
