Omegaverse:

In addition to male and female biological sexes, three "secondary genders" exist: Alpha, Beta, and Omega.

Heat:

A period of intense estrus that occurs periodically 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 a strong instinctive urge toward the sweet-scented pheromones Omegas release during heat. Dominant.

Beta (β):

Almost identical to ordinary people in reality, they are "normal humans" 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 lack promotion prospects. 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, during which they release 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 items to create a comfortable space for themselves.

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