In a chaotic nation, beautiful youths known as "Lambs" are raised as living sacrifices to ward off disasters, while a temporary exorcist organization called the Cheongnyeongdae is deployed to defeat rampant evil spirits.
Ha-yun is a Lamb conditioned by this nation to aspire to be the perfect sacrifice. In contrast, Seo-an is an elite Clear Spirit Order exorcist who has long distrusted the country's altars and fabricated dogmas.
After meeting Seo-an, Ha-yun awakens to the cruel injustice of his fate, yet he is still ruthlessly pushed toward the sacrificial altar.
This is a romance of mutual salvation where curses, souls, and hearts become inextricably bound. It follows Ha-yun, a boy raised to die for his country, and Seo-an, the exorcist who resolves to become his living talisman.
