In a world inhabited by both humans and beastmen, Kai is a young human who has been abandoned by his parents for being born an omega. Luckily, he is taken in by Luard, a wolf beastman and the head of the prestigious Siegfried family. Within the walls of his new home, Kai learns that in order for beastmen to have children, they must mate with a human omega. He dreams of one day becoming Luard’s official mate, yet as he matures and waits for his first heat cycle to arrive, Kai finds Luard increasingly distant. The young omega can't help but wonder—what is his purpose if not to bond with the alpha he loves?
