The dominant omega ‘Rael’, who lived in the dark, plans to take the opportunity to take over the house of the Count when his brother gets into an accident. Rael secretly visits a perfumer named ‘Hyde’ to obtain an alpha pheromone perfume in order to mask his true scent. Rael pretends to be an Alpha in public, and all of this is thanks to Hyde’s special perfume. But, Rael doesn’t know the true identity of ‘Hyde’, a perfumer hidden behind a veil, even rumored to be hideous. But everytime he comes into close contact with him, Rael feels something different… Then one day, the Count declares that if Rael cannot give birth to an Alpha within two years, the Count will hand over the position to someone else. So, Rael asks Hyde, the only person who knows his identity, for help.
