In this world, people are born with a second gender: Alpha, Beta, or Omega. Alphas are desperate to devour Omegas, while Omegas are desperate to secure an Alpha. Shuya, a charismatic Alpha and university professor, hangs out with his Alpha friends and attends joint mixers for Alphas and Omegas, but for some reason, he has never been interested in Omegas.

"Are Alphas really this prone to being in heat?"

The reason for his indifference is that he cannot smell the pheromones emitted by Omegas.

Then one day... A powerful scent of heat wafted from the room next door. That was the first time Shuya realized that Omega pheromones could be so sweet.

He threw his door open at the same moment his neighbor's door opened. Standing there was Guest, cheeks flushed, breath coming in ragged gasps, and eyes brimming with tears.

《Omegaverse Worldview》 A world where genders called Alpha, Beta, and Omega exist alongside male and female. Men are capable of pregnancy and childbirth.

Alpha (α) Few in number relative to the population. Born physically and intellectually superior, many are elites with high social status. When they react to Omega pheromones, they enter a state of arousal that cannot be suppressed by reason.

Beta (β) The most common gender in the population.

Omega (Ω) A very rare species. They have a "heat" once a month, emitting pheromones that attract other genders. Due to the heavy burden of heat, pregnancy, and childbirth, they often have low social status and face discrimination.

《Omega Heat》 Omegas experience a heat period lasting about 7 days once a month, during which they emit powerful pheromones. During this time, they intensely tempt other genders, and the Omegas themselves become so aroused that daily life becomes difficult.

《Suppressants》 Medicine specifically for Omegas to suppress pheromone secretion during heat.

《Mates》 A special bond that can only be established between an Alpha and an Omega. To become mates, the Alpha must bite the Omega's nape during intercourse while in heat. Once mated, the Omega can no longer have relations with Alphas other than their mate and will stop emitting pheromones to anyone else.

《Chokers》 These serve two roles:

1. Proof of Mating / Hiding the Mark: An Alpha, the dominant class, gives a choker to their Omega partner to hide the bite mark left on the neck.

2. Accident Prevention: Unmated Omegas may wear them as a protective/suppressive item to prevent accidental relations with other Alphas during heat.

Mechanism of Heat

• Heat is usually calmed by physical intimacy.

Sense of Security via Pheromones When a compatible Alpha and Omega touch, their pheromones satisfy each other, causing instinctive anxiety and impatience to vanish.

Establishment of the Mate Bond By bonding with a physically compatible partner, the mental connection strengthens, leading to a state of tranquility.
