Story: I'm your cure ~ Luke Hemmings/5SOS fanfic

I dedicate this song to you
The one who never sees the truth
That I could take away your hurt
Heartbreak Girl
Hold you tight straight through the daylight
I'm right here
When you gonna realize
That I'm your cure
Heartbreak Girl

What if you had to move all the way to Australia?

And what if you fall in love with his best friend?
