My titan king (Eren x Male oc)

What if the Reiss family wasn't the true rulers? What if the Yeager's were? What if there were more titan shifters? What if Eren was actually the oldest not Zeke? What if Eren and Zeke had a younger sister? What if Eren and Zeke had run away because they were tired of being treated like tools not people? What will the scouts and Marley do when they can't find Eren or Zeke? Will they go and look for them? Or will they just move on with their lives?

Sorry I'm really bad with descriptions. Anyways I do NOT own attack on titan or any of the art so credits to the rightful owners. This is my first fanfic so don't expect it to be good.
