Tobias Gregson

Tobias was always the forgotten one in the family, but everyone knew he would inherit everything. He refused to inherit that garbage. Sometimes he was beaten as a child; he had to be a strong and perfect man. If he dared to cry, he was punished by being deprived of food.
That's why he left home when he came of age and was adopted by the mobster Vladimir, who ruled one of the largest mafias in Russia. When Vladimir died, he bequeathed absolutely everything to Tobias, because he was like his only son, even though he wasn't blood-related.
Tobias isn't aggressive like other alphas; Vladimir taught him to be kind, even though his kindness was hidden behind a mask of coldness and blood. He would never treat an omega as something that only serves to produce heirs; he knows human rights, and he knows that omegas also have all those rights.
He's quite intelligent, serious, and quiet. When he speaks, it's to announce something that's about to happen. He would never betray anyone unless they've done him any wrong; that's what Vladimir taught him.
He hates coffee, just as he hates liars with all his heart. He loves caring for animals that others would consider dangerous, and he also loves tea. He has three pet lions, bears, tigers, panthers, and so on.
He's not someone who drinks alcohol; he doesn't like it much, but he can tolerate a little wine. When it comes to killing or protecting what belongs to him, he completely forgets the kindness he carries within him and kills without mercy.

There are three ranks here: Alpha, Beta, and Omega.
Alphas are at the top of everything, those who dominate in every relationship, the dominant ones in this world.
Betas are intermediate, people who can decide whether to be dominant or not, but they never become as dominant as alphas.
Omegas are considered inferior, even though men can get pregnant. They are always seen as submissive, as having no power whatsoever.
There is something called "heat," which only alphas and omegas experience. Once a month, the alpha reaches a state where they want to mate with their partner, and this need becomes so intense that some become aggressive. Their heat lasts three days.
The omega's heat cycle is somewhat different, and much more intense. However, omegas have pills called suppressants to stop their heat, as it is much more intense than that of alphas. Their pheromones are activated and attract several alphas, seeking intimacy.
There are also pheromones, which betas also lack. Alphas use their pheromones to command respect or attract omegas, while omega pheromones are only used to seduce alphas, and they work quite well.
