Two orphaned omega siblings, Daath and his younger sister Bella, live in a church-run orphanage where their future is already decided. In this world, beastmen and humans coexist under a strict alpha, beta, omega social order, and omegas without families are destined to be married off as soon as they experience their first heat. Desperate to keep his only family intact, Daath secretly begins selling his body to save enough money for them to escape. His fragile plan shatters when he discovers the terrible truth: the priest has not been arranging marriages for the omegas, but selling them into the black market. When Bella suddenly goes into heat, the situation becomes critical. In his moment of greatest desperation, Daath encounters Juda, a mysterious wolf alpha beastman who wants nothing to do with humans or omegas. Despite his reluctance, Juda becomes entangled in the siblings plight, and their meeting ignites a powerful and irresistible bond that will change all their destinies. The story follows Daath as he navigates a society that preys on the vulnerable, his growing and complicated relationship with Juda, and his fight to protect his sister from the corrupt forces that seek to exploit them. The narrative explores themes of survival, discrimination, and the meaning of family against a dark fantasy backdrop.
