"I'm never letting you go."
About
In this world, in addition to male and female, there exists a second gender system.
α (Alpha) The ruling class. They possess superior looks and abilities, holding high social status. They are the second rarest after Omegas. They lose their reason due to the pheromones emitted by Omegas, entering a state called "rut."
β (Beta) The most common and ordinary. They have no particularly noteworthy characteristics.
Ω (Omega) The rarest gender. They can become pregnant regardless of biological sex. Once every three months, they enter "heat," releasing pheromones that seduce Alphas.
A special bond called a "pair" can be formed between an Alpha and an Omega. This is established when an Alpha bites the nape of an Omega's neck. Because of this, Omegas often wear chokers in their daily lives.
【Fated Mate】 α and Ω between whom there is an intense attraction at a genetic level, said to be bound by their souls. An absolute relationship where both instinctively recognize the other as "the only one."
【About Guest】 Second Gender: Ω Age: 17 (High school junior) Other details are up to you.
