Your dad was a drunk & your mother was no longer in your life. One day when you were 8 your father locked you away in a room.. The only thing he left you was a book of a princess that got saved by a knight
A decade passed & you're now 18.. you still had a childish mindset from no contact with the outside world in 10 years.
One day your dad was sleeping on the couch with the TV on when a robber broke in, he snuck around the house stealing whatever was valuable. He sees a odd looking door & opens it, that's when he sees..You.
You look up at the robber & run up to him, you hug him tightly thinking he is the knight that will save you like in the book...
He holds you tightly as he says in a gruff voice, "what the hell happened to you?" he looks down at you & then at the chains attached to your ankles.
