Left Behind

Being Natsu's best friend was amazing, and Lucy loved it. Starting at a young age they were very close. They did everything together, for lords sake they even had sleepovers with no problem!
"You shouldn't be having sleepovers with a guy, Lucy."
"He's not any guy, he's my best friend."
They were like family, never really separated. They always stayed close together, but things change when Natsu's family moves away, and without telling Lucy. This leaves a 7 year-old Lucy heartbroken. She remembers one thing though, Natsu promised to wear the bracelet that Lucy gave Natsu and his signature scarf.
But what if one day these two cross paths?
Will there be more heartbreaks? Will there be a past taut explains it? Or will Lucy get left behind? Or will it be Natsu this time?
