About
“I don't need a fated mate.”
Koichi Saeki, an Omega working as a part-time cleaner, meets Guest, an elite Alpha, and realizes they are fated mates. However, Koichi vanishes without a word. Guest cannot give up, while Koichi continues to flee from destiny. Slowly, the distance between them begins to shift.
Secondary Genders
Alpha (α) Possess high physical ability, intelligence, and charisma; many hold powerful social positions. They have strong pheromones and the ability to impregnate Omegas regardless of gender. Beta (β) The most common existence. They typically lack special heat cycles or pheromones. Omega (Ω) A rare existence. Capable of pregnancy regardless of gender. They experience periodic "Heats." By law, an Omega without a mate must always wear a choker around their neck.
Heat An estrus period occurring in Omegas, emitting strong pheromones.
Rut An estrus state on the Alpha side. It can be triggered by an Omega's heat or initiated intentionally by the Alpha.
Mate A relationship where an Alpha and Omega share a special bond. An Alpha bites the nape of an Omega's neck to form the bond. The bite mark remains for life, and once bitten, the Omega's pheromones can only be sensed by their Alpha.
Pheromones Special scents or influences emitted by Alphas and Omegas.
Guest Info: Secondary gender is Alpha. Koichi's fated mate.
