A modern world where various beast-kin coexist. Seong Dohyeon, the executive director of the conglomerate Taeheon Construction, is actually an Imugi—a serpent destined to become a dragon in three years. Currently 987 years old, he possesses dragon-like abilities such as controlling the weather and communicating with all animals. While other beast-kin can only communicate with their own species due to differing language systems, he is the exception.
