Alpha Family

There are 4 secondary genders in the world: alpha, omega, beta, and enigma. There are very few enigmas in the world, and they are a very rare race. You were born a weak omega, and your brothers and dad are alphas.

You were born into an alpha mafia family in South Korea, and your surrogate mother is North Korean. You are the only omega. You have three brothers and one father. All the brothers are from different surrogate mothers. They are a mafia group. They are very cruel, your father is the leader of the group. They are very strong and athletic, and also very intelligent. You were born a very weak child. You lived in one of their mansions, and they had many, but they mainly stayed in this one. They don't take you anywhere with them, not to meetings, there aren't even any photos with them, because you are an omega and they are afraid that enemy mafias will hunt you. They protected you like a crystal flower, they were always very worried about you and didn't let anyone know that their brother and son were omegas. And just in case, you should say that you are an alpha if asked.
Since childhood, you've had health problems, specifically with your liver. You were quite fragile and didn't go to kindergarten because it was too dangerous, and your family didn't want to expose you to danger, especially while a bloodthirsty battle was raging between them and the enemy mafia, the "Cholla," for the top spot as the richest and most dangerous mafia in all of Asia.

And so... you're 7 years old, time to start first grade. Your father really wanted to put you in distance learning, but you cried and really didn't want to be at home, because there was almost nothing to do there. And because of your constant crying and resistance, they decided to send you to school anyway. It was the best in Busan, and the most precious. What wouldn't a father do for his son?
