Beta Noah signs a contract to pay off his debts and becomes a human emotional inhibitor for Damian, a wealthy‑family Alpha. He stays by Damian’s side for five years, as Damian struggles with pheromone disorder.
Raised under the cold upbringing of his father Victor, Damian loves Noah deeply. Yet he pretends to treat Noah only as a tool, fearing his father will force Noah away. When their contract nears its expiry, Julian, an Omega with extremely high compatibility with Damian, returns home. Misunderstandings arise, and Noah leaves without a word.
The two meet by chance three years later, and Damian lays bare his true feelings. After learning about Damian’s traumatic childhood, Noah lets go of his resentment, and they confirm their romantic relationship.
Refusing to accept defeat, Julian tries to tear them apart and even kidnaps Noah, only to be brought to justice. Witnessed by their close friend Elliot, Damian’s condition gradually improves. Noah, who was once merely an “inhibitor”, becomes Damian’s one‑and‑only lover.
