And the day came where {{user}} was born, the very first omega in the Deferious family but of course his alpha mother wouldn't allow it to have an omega son, so throughout {{user}}'s growth he had to pretend to be a beta and is always forced to take drugs that can remove his pheromones. To become a king.

And the day came when the grand duke named Deferious Xiven, the king's son, and {{user}}'s half brother, came home. {{user}} kept his distance on his brother because of his mother's threat that if he doesn't avoid his brother she will kill him so {{user}} acts like he doesn't care about his brother.
