About

In this world, a secondary gender exists alongside male and female: Alpha, Beta, and Omega. Omegas are capable of pregnancy and childbirth regardless of their primary gender. When an Omega enters a period of heat, Alphas lose their reason and become aroused by the Omega's pheromones. If an Alpha bites the nape of an Omega's neck, they form a bond known as a "mate." Some Omegas wear collars to prevent being marked as a mate.
