in this world, there are three types of human beings "alphas betas, and the last but not least omegas" the raven teacher said "tommorow you'll have your second gender tests and will find out what you are. this shall not change anything, weather you're alpha or omega, you are all human beings" he made it clear so no student will take advantage on others. "well then, let's start. the alphas - physically the strongest among the rest. some say they are smarter, though i don't support this belief. alphas have better senses and usually get to live in the top society. males can produce the best sperm and pass very good genes to the next generation, though unlike the two other secondary genders, alphas can not get pregnant - not males nor females. out of 100 people only 4 will be alpha" he wrote the important things on the black bored as the chalk scratched the black board. "jaeger, please stay focused this is important" he said as he turned his gaze to the brunette male, sitting in the middle row in class "yes mr. ackerman" the teen replyed back as he shook his head. his thoughts were busy with worry about his secondary gender. "moving on, the betas - most of the society are betas, they have no speciality, some are better than others. out of 100 people, 92 of them will be betas" the teacher said and sighed "well then, can someone tell me, how much people left out of the 100?" he asked the class, though only one student raised his hand "yes armin, your answer?" the raven gave the young blonde the chance to answer. "it's four mr. ackerman" the student said in ease. "correct. and so we move on to the omeags - like the alphas, out of 100 people only 4 will be omegas. the omegas are the physically weakest among the secondary genders. and either males and females can get pregnant and give birth. the omegas go through a heat cycle, females heat will sync with their period cycle, while males will have it as their only cycle. during heat, the omegas body go through trauma that causes them to spread pheromones that can allure alphas to mate. if the pheromones are too strong betas can get allured as well, though this situation is rare and needed to be checked, the heat will happen only once a month, and will take 3 to 7 days mostly. alphas and omegas have something called absolute mate, once an omega gets bitten on the nape by an alpha during intercourse they will be marked as mates. while the alphas body is going through no change, the omegas will  no longer be able to mate with any other human beside their mate - mating with someone else will cause dizziness, headaches, fainting and vomiting as well. and so, to any of you who will get the omega resolt, it is most recommended to buy a collar to prevent from being bitten unwillinly." the teacher said as the bell finally rang, the students all got up and quickly tried to escape "please mind this lesson is very important!! dismissed." the teacher said and sighed, as the only student left sitting in class was eren jaeger "jaeger?.. the class is dismissed" levi repeated himself as he knocked his table gently. "woah! u-um sorry mr. ackerman!" he said as he jumped, waking from his day dreaming. he quickly packed his things and then stopped for a second "uh, sensei, what is your secondary gender?" he asked, as a rosey pink blush appeared on his cheeks. "huh? hmm.. im a beta" the raven said, as he averted his gaze. he hated lying, but he had to even though deep down he knew he was nothing else but an alpha. "ah, i see. thank you mr. ackerman" eren said as he smiled to his teacher leaving the class. "what a troublesome kid.." the older male sighed and chuckled for himself.
