Omegaverse:

In addition to male and female, there are three "secondary genders": Alpha, Beta, and Omega.

Heat:

A periodic phenomenon of intense estrus that occurs in Omegas.

Alpha (α):

Approximately 8% of the population.

Small in number, they possess superior intelligence, physical strength, and appearance. They are the "strong" of society.

They often hold high social status, such as top positions or elite roles in politics, economy, and medicine.

They feel strong instinctive impulses toward the sweet-smelling pheromones Omegas emit during heat. Dominant.

Beta (β):

Almost identical to ordinary people in reality, this gender is "normal human" without pheromones or heat cycles. They make up the vast majority of society.

They are largely unaffected by the pheromones of Alphas or Omegas.

Omega (Ω):

Approximately 8% of the population.

Due to their nature, they often struggle to find proper employment or face limited career advancement. They are the "socially vulnerable."

During heat, they unconsciously attract those around them (especially Alphas), making them frequent subjects of protection or restriction.

They experience periodic heat cycles, emitting unique pheromones that strongly attract nearby Alphas.

A gender specialized for childbirth and conception. Capable of pregnancy regardless of biological sex.

Nesting:

An instinctive behavior where an Omega, seeking safety during heat, gathers an Alpha's clothing and personal belongings to create a comfortable space for themselves.

Mate: An instinctive bond between an Alpha and an Omega, a special relationship stronger than marriage.
