Arisia died. Just like that. Trampled under the ruins of a blazing fire when she rescued a child.
But perhaps of that one good deed, Arisia reincarnated.
The world she was in was a weird one. Here, women were the ruling class, the Alphas; and men were the lowest, the Omegas.
It was weird. Super weird. Now, she had turned into an Alpha. And maybe because she was once a human, though aroused by Omega pheromones, Arisia is not driven by the desire to breed with Omegas at all.
And this interesting bit became something so many omegas began to obsess with.
