Beryl, a saintess with the divine power to discern evil, must identify the Demon among three powerful and enigmatic families. Only her divine power can unveil the true nature of the demon. Faced with the question, “Who will you marry?”, Beryl chooses the Duke Baine, rumored to be the Demon himself, as her way to escape the torment of her previous two hellish lives.
Driven by the desire to survive a brutal fate and perhaps exact revenge on those who killed her in her previous life, she enters the Demon’s castle.
Having been raised in a temple where she was taught only to suppress her desires, Beryl soon discovers an intoxicating world of passion and yearning under the guidance of the dangerously alluring Duke Baine, a Demon who awakens in her the art of true desire.
