Haikyuu Mafia ( A Tendou x Reader )

The Beginning... - Chapter 1

Y/N was just arriving at Karasuno High School for your first day. You could hear some of the boys who were talking about you,
Boy 1 - "Yh she's fine"
Boy 2 - "Don't try it she's gonna be mine.."
You just decided to ignore all the boys talking about you. Nothing really happened on your first day it was just like any other day. It was finally the end of the school day and you were waking home, you decided to take a shortcut through the ally way when you heard shouting from it. You decided to look and saw three cut boys.
???: "BOKUTO WTF YOU GOT BLOOD ON ME!"
Bokuto: "NOT MY FAULT UGLY!!"
???: "Kuroo and Bokuto stop now!"
Then you stepped on a twig and all their attention when to you..
Y/N: "F*ck"
You decided to make a run for it with the three pretty boys changing after you. A little while later the boys finally caught up to you and knocked you out.. Hours later you woke up with the two of the three pretty boys in your face.
Kuroo: "Hello chibi-chan my name is Kuroo and this dumb f*ck is Bokuto, oh Yh and the guy behind you is Tendou."
Y/N just stayed silent as you could feel a gun pointing at the back of your head.
Bokuto: "Mind telling us to your name..?"
Y/N: " Why should I, whats it to ya?"
Bokuto: "It's how a convocation works I tell you mine, which I already have, now I it's your turn :)"
Y/N: "Tch, my name is Y/N"
Everyone is silent for a second, then moments later you break out and grab Tendou's gun.
Y/N: "NO ONE MOVE OR I'LL SHOOT YOU!!"
Kuroo: "Cmon we all know you won't."
You shoot kuroo's foot and everyone just awes at you.
Kuroo: "you b*tch.."
Y/N: "DONT TEST ME!"
You run away to your apartment without knowing someone is following you...
