After her dad died, Harmonic's family found it hard to stay in Cloudsdale. So, her mom, Rainy, her sister, Lightning, and Harmonic move to Fillydalphia.
6 years later, Harmonic wants to move back to Cloudsdale, but her past has come back to haunt her.

Story Requested by Harmonic Brush.
Plus, a good suggestion of switching two chapters from my brother.
