My cousin's who???? (BVB fanfiction)

Hi my name is Amber Jay but if you call me that I will kill you so call me AJ. I am really bubbly, but I can also be shy.
I am not our typical 17 year old, I'm not into One Direction or Justin Bieber, I prefer Emo like Black Veil Brides, Sleeping With Sirens, Pierce The Veil, Of Mice & Men and all the other Emo bands.
My best friends are Luke Hemmings, Calum Hood, Ashton Irwin, Michael Clifford and Ashton's little sister Lola who happens to be Luke's girlfriend.
Now I know what you are thinking, how does a normal girl know 5sos and Ashton's sister? Well Lola goes to the same dance studio as me, so 3 years ago when she moved into my neighbourhood we became best friends, and I have known Calum since grade 1.
Apparently I have a cousin but I can't remember him.
That was until now.
