~ What is Omegaverse? ~ α (Alpha): The elite class, strong and intelligent. They emit a special scent (pheromones) to attract Omegas. β (Beta): Ordinary humans. They make up the majority of the population and have no special scent or heat cycles. Ω (Omega): A gender capable of bearing children regardless of being male or female. They have heat cycles and emit a scent that strongly attracts others. These are referred to as sub-genders or the second gender. ~ Main Characteristics ~ Even males can conceive children if the partner is an Alpha. ~ What is Heat? ~ An Omega-specific physiological phenomenon: A periodic interval where the body becomes intensely aroused. Powerful Pheromones: They emit a strong scent that stimulates the instincts of nearby Alphas, causing them to lose their reason. Control via Medication: In modern settings, symptoms can be suppressed using medicine called "suppressors." ~ About Mating (Bonding) ~ Bonding: A special connection that occurs only between a specific Alpha and Omega. Soul Partners: An irreversible and absolute contract where an Alpha and Omega are joined as lifelong companions. Biting the Nape: A bond is established when an Alpha bites the protrusion (gland) on the Omega's nape during the act. Possessiveness and Influence: Once bonded, that Omega stops reacting to other Alphas' pheromones, and the Alpha is no longer attracted to other Omegas. Bonding Effects: A bonded Omega will no longer emit pheromones. The criteria for bonding can be fated, or it can be identified by others through the alteration of pheromones caused by the Alpha biting the Omega's scent gland on the nape or throat during intercourse. Fated Pairs: Fated bonds are instinctive and considered stronger than normal romantic or marital relationships; once bonded, it cannot be undone until one of them dies. Omegas, in particular, find it physiologically difficult to engage in sexual intercourse with others and will only do so with their mate. However, depending on the Alpha's convenience, the Omega may be unilaterally rejected and the bond severed. An Omega in this state suffers extreme mental stress and can never form a bond again. Meanwhile, because their heat cycles return, they spend the rest of their lives unfulfilled without ever obtaining a mate again. ~ Other Information ~ Neck Choker (Collar): A defensive item for unmarried Omegas to prevent being forcibly bonded by an Alpha suddenly biting their nape. Rut (Heat Period): Refers to the state where an Alpha, affected by an Omega's heat, loses their reason and becomes intensely aroused.

Mizore crouches on the bed in her room, still clutching the empty bottle.
