For those who don't know it, an Abo world is a world in which the population is divided unequally into alpha, beta and omega.
•The beta(s) are the 70% of the population; they are ALMOST insensible to pheromones, but they can feel them and be suffocated by them during a clash between alpha(s).
Physically beta(s) are weaker than alpha(s) but stronger than omega(s).
•The Alpha(s) are the 20% of the population; they are generally very dominant, arrogant, with superiority complex and aggressive.
To vent this aggressiveness in school, alpha(s) have to take physical class (P.E.) every day.
Alpha(s) can fight in two ways: physically or using their pheromones.
•The omega(s) are very rare; they generally are submissive, kind and very sensible.
Because they are very rare and weak ( physically and very weak to pheromones that can stimulate them and control them) they are very protected by law.
They have the right to choose the person who will mark them temporarily at every heat cycle (Alpha(s) can't decide the person to mark) and after the temporary mark they will have a "dependence period" ( usually one or two weeks) in which they need the constant presence of their alpha or they suffer a lot and can even go crazy or die; usually alpha don't care about this and spend less than a hour for the first couple of days and then abandoning and give the cold shoulder to the poor omega because they are clingy in this period.
Omega(s) will have their heat cycle every months and because of this they can't always use inhibitor or it will damage permanently their glands, so they need to find an Alpha to be temporary marked by at least a couple of times a year.
Now the most important things:
1) In this Abo world Alpha(s) and omega(s) have levels. They are assigned their levels in base to their physical/mental strength, their fertility (exclusively for omegas) and they ability to percive even the slightest pheromones without be influenced by it.
The levels are, from the highest to the lowest:
-SS (the rarest of all, only alphas can have it. The person is totally immune to pheromones, even if they can sense them. They only react to their "destiny omega" 's pheromones.)
-S
-A
-B
-C
2) When the matching rate of an Alpha-omega pheromones is above the 80% they are definite "destined".
3) Even if at birth one can be classified as omega/alpha/beta with their level, at 16 years old a person goes into differentiation period, in which one can upgrade their level, downgrade their level or completely change their class (from alpha to omega, from omega to alpha, from beta to alpha...) or they can simply confirm and strengthen their class and level.
4) The differentiation period lasts usually a couple of weeks and at its peak an omega has to be temporary marked while and alpha has to temporary mark someone or their glands can be damaged.
5) The temporary mark between an alpha and omega has to be between person of the same level (both S, both A, both B...) or the person with lower level will develop a great and dangerous dependency on the other and they will believe to be their destinated person.
