My brothers band mate

Lily is a girl who has a famous brother Michael Clifford. Michael is in the band 5 Seconds Of Summer with Lily's boyfriend ashton Irwin who is also the drummer of the band but there is one tiny problem. Ash is 23 and Lily is 17 which means Michael does not like their relationship. But the age gap doesn't stop Ashton and Lily from dating. Lily has a little problem at school though. She gets picked on and beaten up every time Ashton goes on tour with his band.
