nerd living alone

Hi I'm Diana Harvey, I'm 17 years old and I'm a nerd as most people from my school call me. I live alone because we'll my parents...let's just say, was the worst day in my life when I lost them both in a car accident, when I was 5. Went to a foster home, was almost rape by my foster parent, was abuse everyday,and starved to deaf. So when I turn 12, I ran away for my foster parents.Which lead to homeless, on my third night a group of men surround me, because I was sleeping on the street. Then that's when the man who save me from being rape, took me in asking question about my family, which I said I had no family. So he took me in as his own, his name is Jake Anderson, when he took me in he was 21 years old ,who he says was a street fighter and also taught me how to defend myself from any harm but he took care of me. When I was 12 I join street fighting. He my manager, when I turn 15 I moved out cause I didn't want to a burden in his house so I fight for a living at night my usual self my street fighter name is "dead pool", I know right weird name but people gave me the name on my first fight I won. which I wore a mask and my hoodie over my head so people from the underground won't know who I'm in the real world and that is why, I dress like a nerd. Everything was going to the good, but that stop when Jake was in the hospital when he got shot in the head when was walking out of a store. Which was hard so I decided to move to New York, still have to be a nerd,which hopefully stay like that thought my last year of high school.

Do you think everything would be the same without Jake?
And will her nerd secret safe till high school is over ?
Will she has trouble in New York?

cause some bad boy have to ruin her secret,which the name he goes by " Kyle Jake".
