Asus, the first prince of the demon realm, defies the Demon King’s will and lives a life of reckless abandon, ultimately resulting in his exile to the human world. Determined to reclaim his lost power and secure his return to the Demon Realm, Asus attempts to replenish his energy through intimate union with a mortal man. However, his efforts repeatedly fail as no human possesses the endurance to handle his overwhelming demonic constitution. Teetering on the brink of collapse due to a severe depletion of magical power, Asus finally crosses paths with Gaji-Nam, who is walking home carrying a Bible. Believing he is facing imminent death, the desperate prince pleads with the stranger to save him. Misinterpreting the situation entirely, Gaji-Nam agrees to help with a stern condition, demanding that Asus accompany him to atone for his lifestyle: "Fine, I'll do it for you, so come with me to repent!"
