Shhh... It's our secret (teacher/student relationship)

Krystal Harris is a 17 year old girl. She is starting her senior year at her local high school in Santa Rosa, CA. She doesn't have a normal life like every other 17 year old in her school, even though that was what people thought. She's living in a house where she is beaten, every single day. She has to obey her "masters". She doesn't like calling them her parents. They are horrible people. How could they beat their own daughter? How? The question she asks herself every single day, yet she still has not found the answer. She can't think if anything she has done to make them hate her. She is a only child, she was happy about it, she wouldn't want anyone to have to live through the hell she was going through.
She doesn't have friends eighter, she is a loner in school and the popular girls enjoy picking on her, they laugh every time she cries. She has stopped crying, it only made matters worse, both at home and school.
