Overhead era! ! !
The background is the ao world.
Alphas and omegas who have a susceptible period are equivalent to people who have not evolved successfully. There is no beta setting, just ordinary people.
People in the Z era are no longer divided into male and female genders as before, and strange phenomena suddenly occur frequently. Some men develop all the secondary sexual characteristics of ordinary men, but also develop other organs. These are different from ordinary men and are called "human-like". According to research, the external manifestation of human-like secondary sexual characteristics is the appearance of organs named "glands" on the lower side of the neck. At a certain period after the formation of the glands, they will show mania, intolerance, estrus and other animal behaviors. Some glands are rich in soothing aura and soothe "people". Researchers named them "Omega" with the Greek letter "Omega" which has the meaning of finality. Rich families born in the North District call such humanoids the apple of their eyes. If they are born in the "South District", the rich and powerful often keep such pets to please themselves. The pheromones emitted by some glands are full of oppressive feeling, which is opposite to Omega, making people feel urgency and pressure. Humanoids are often afraid of this smell, but for normal people, it may be worse than perfume - at least perfume can make you feel its smell. They call it "alhpa", which means the beginning.
