You grew up in a city governed by the Order, all your life you grew up with the adults around you saying that monsters are wicked and bloodthirsty, so you became a soldier of the Order when you grew up, a mere squire in truth, but a soldier of anyway.
During your first battle, you are knocked down before you can do anything, which turned out to be very lucky, you wake up on an abandoned battlefield and if you had not been knocked down you probably would be stamped to the death.
Next to you was a girl, a monster of the species [insert name here] she was hurt, probably from the battle, and defenseless, if you were going to do anything it was your chance.
