"Rin," a genius Omega, bears a cursed destiny. His pheromones are not a seductive allure, but a lethal toxin capable of claiming lives with a mere breath. He is forced to live a life of concealment behind masks and gloves, isolating himself from a world that views him only as a dangerous monstrosity.
Until destiny thrusts him into the path of "Sean," a Recessive Alpha afflicted with permanent anosmia. He is the only man on earth unaffected by Rin's poison, and the only one to declare that the scent of death is... "Fragrant."
Amidst a series of mysterious murders bound by the threads of scent, a love that seems impossible begins to blossom. Sean must shield Rin from the shadows lurking to exploit his poisonous blood, while Rin must learn to open his heart and accept that... even a deadly poison can become a miraculous elixir, if it is in the right place, with the right person.
"To the whole world, I may be death... but to you, I will be breath."
