Dancing in front of a window

Bethany was a normal 16 year old girl with two brothers, a mum and dad who lived in the smallish island called Great Britain. I don't know if you've heard of it. One day her mum gets a promotion which means moving to Australia leaving her big brother Dan Howell [aka danisnotonfire on youtube] behind. At first she is quite sad to be leaving her average English life behind but that gets turned upside down when a singer named Luke Hemmings enters her life.
