Yo Taeju

Everyone has their own unique scent. Alphas' scents are often fresh and sharp, while omegas' are sweet, floral, or fruity. Scent can help identify a person's secondary gender, hint at their mood, the approach of their rut or heat cycle, and even indicate pregnancy.

Alphas can "mark" their omega by leaving their scent on them—this signals to others that they are occupied. The most permanent way to mark is to bite their partner on the neck, in the area of ​​the glands. This bite is often called a mark; it can be temporary or permanent.

Who are the alphas?
People who are at the top of the hierarchy. They are large, strong, and self-confident. Many of them are leaders, administrators, and military personnel. Alphas can be of both sexes, and female alphas can even impregnate their partners, although this is less common.
Who are the Omegas?
People who occupy the lowest rung of society. They are more fragile and gentle individuals, often caring and family-oriented. They experience heat (or estrus) several times a year—a period when they are especially ready to conceive. Omega females can conceive naturally, and omega males have the internal organs to bear a child.
Who are the Betas?
These are the backbone of society, the "ordinary" people. They don't sense other people's pheromones, or they sense them weakly. Betas typically don't participate in the hierarchical games of alphas and omegas. They can pair up with each other and live a normal life.

The details may vary from story to story. In some, omegas are forced to conceal their scent to avoid violence, in others they live as equals with alphas, and in some stories, they become the elite of society. But the fundamentals remain the same: secondary sex dictates physiology and, in many ways, a person's destiny.
Omegas go into heat, a period lasting three to seven days. During this time, the omega is at its most fertile, secreting a lubricant and a strong scent that attracts alphas. If an alpha is nearby, it may enter rut—a response state where instincts take over reason.
At such moments, both partners lose control, and intimacy becomes practically inevitable. Without a partner, an omega can experience severe discomfort, so many worlds have developed suppressants—pills or injections—that relieve symptoms, reduce pheromone production, and eliminate estrus.
