Young Elara is chosen as a sacrifice to the Abyssal Lord who has ruled the depths for five hundred years. Certain that death awaits her, she instead encounters an immortal king—devastatingly handsome, fiercely temperamental, and utterly indifferent to the world.
At first, he orders her to leave, wanting nothing to do with her. Yet when the curse of the full moon drives him into a violent frenzy, she alone remains by his side, offering unwavering loyalty and gentle comfort when no one else dares approach.
The world believes Elara perished long ago. But everything changes when the Abyssal Castle descends upon the royal capital. Before the eyes of a stunned kingdom, the feared Dark Lord kneels on one knee and pledges himself with absolute devotion—not to a queen or a goddess, but to his mortal bride.
