I Will Never Be Yours
In the year 3XXXX humanity's numbers have dwindled to only a couple thousand. In order to save themselves from extinction, humans have injected a serum into their bodies that give them the attributes of wolves. As a result, there are no more full blooded humans and the world is run by "half breeds". These half breeds group together in packs and have a hierarchy ruled by their wolf instincts.
In the year 4XXXX
Eren Jaeger is born to Alpha Grisha and Luna Carla, who have been waiting for their first wolf pup to be born. Unfortunately Eren is born as an Omega, a sign that the pack is weak. Out of love for Carla, Alpha Grisha does not kill Eren but neglects him instead. After a failed attempt to escape , Eren is sold to another pack for the price of 5000 dollars. Unknown to Eren, his mate controls the pack he is sold to is no other than Humanity's strongest Alpha; Levi Ackerman. After meeting Levi in person, Eren vows that he will never be his but could he have a change of heart?
