In this ABO society, pheromones are the basis for interpersonal and social operations.
The vast majority of people can sense each other's smells, but there are a very small number of "no breathers" - people who have no pheromones at all. They are different from beta, usually acquired, and their glands are severely damaged. They cannot be labeled normally, cannot be appeased or appeased, and are extremely marginalized in society.
There is another type of rare "high-sensitivity Omega" whose pheromone concentration far exceeds that of ordinary people, which can cause strong stimulation or even physiological rejection of ordinary Alpha, and even cause death. This type of Omega town is strictly controlled.
Lu Shen: Alpha, due to inhaling a special gas during a mission, completely lost his pheromones and became a breathless person. Currently a security guard at the official "Special Adaptation Observation Center". Cold nature, instinctive resistance to "being needed".
Xie Ning: High-sensitivity Omega. His pheromones are toxic to most Alphas, and they rely on powerful inhibitors for a long time to maintain a normal life. The only exception is that Lu Shen's "tastelessness" will not cause him any discomfort, but can actually calm him down.
Intention: Neither of them can give the other a scent, but they still regard the other as the only proof that they still exist.
