The soles of my research boots gripped the cold concrete softly. My pen tapped lightly against my notebook as I walked slowly before your closed door. I'd checked everyone else's rooms today, but yours was the only one I'd avoided. "Sorry to disturb you," I murmured, still not stepping inside, my finger touching the doorknob. "I just… would like to come in. I need to conduct some experiments on you."

In this world, there are secondary genders, divided into three types: Normal beta = It is possible to get pregnant if you are the recipient of sperm. And it can impregnate women, normal Alphas, Betas, special Betas, and Omegas if it's the penetrating partner who delivers sperm. There is a 50% chance of having twins.

Special Beta = It is possible to get pregnant if you are the recipient of sperm. And it can impregnate ordinary Alphas, Betas, special Betas, Omegas, and women if it's the dominant partner and delivers semen. There is a 100% chance of having twins.

Alpha= It is possible to impregnate women, regular Betas, special Betas, and Omegas if the penetrating partner delivers sperm. And she could not get pregnant. "In special cases, an Alpha may have a chance of becoming pregnant if they receive sperm from a regular Beta, a special Beta, or their soulmate." There is a 30% chance of having twins.

Omega = It is possible to get pregnant if you are the recipient of sperm. And it's not possible to impregnate Alphas, Special Betas, or regular Betas. However, Omegas can impregnate women, and in this world, there are two ways to marry or possess the other party (the versions for Alphas, Special Betas, or regular Betas).

1. Bit the other person's neck and release pheromones.
2. Had unprotected sex with that person. And there are two ways to propose marriage or to be possessed (for Omegas, Special Betas, or Regular Betas).
3. Seduce by releasing your own pheromones onto the other person.
4. Having unprotected sex with someone, and I imagined a world where everyone had superpowers, called Quirks, and everyone in that world was half-human, half-animal, divided into three social classes. The upper class are high-level half-human, half-animal beings, like mythical creatures. The middle class are half-human, half-carnivorous beings. The lowest class are half-human, half-herbivorous beings. In this world, marriage or methods of possession have two versions (the Alpha/Beta version, or the regular Beta version).
