Basic structure
In this universe, people aren't just "men and women"—they also have a second classification:
Alphas (α)
They tend to be more dominant, confident, and intense.
They can influence others through their presence/pheromones.
They are often seen as leaders.
In stories, they often have a protective side (or sometimes a controlling one, depending on the author).
Betas (β)
They are the most "normal" ones.
They don't have instincts as strong as alphas/omegas.
They act as a balancing force in the world.
Omegas (ω)
Generally more sensitive (emotionally or physically)
They have more intense instincts (like strong emotional bonds), and are seen as vulnerable.

Pheromones
The characters have "natural smells" that affect others:
They can cause attraction, calmness, nervousness, etc.
Example: an omega might become more nervous around a specific alpha.

Cycles
Heat (estrus) → period when the omega becomes more sensitive and emotional.
Rut → most instinctive phase of the alpha
