Promises {Levi x Fem! Reader}

We start off at age 10, both your parents are murderers, but they only murder those who kidnap, assault or do any other awful things to others. Both your mom and dad have been teaching you hand to hand combat and how to use a knife.

Though..
At midnight you wake up to the floor creaking from footsteps, the bedroom door slamming open as three random men come running and murder your mom, as your father wakes and tried to hold them back he tells you to run, you do as told by escaping through the window next to the bed. When you turn to see if your father was following behind, you see him being murdered, then the two men chase after you.

After a minute of running you trapped yourself into an alleyway, when the entrance is blocked by the men you try and fight back, but you couldn't handle the three, as you're pinned and about to be stabbed, a boy with black raven hair knocks the three men dead.

That's when you met him, the boy who will be there for you, he'll protect you when you can't. Right...?
