Music in our hearts: A Miraculous Fanfic

Melody is a princess from Luminia. She grew up and lived there her whole life, the oldest of 10 children (or so she thought), until she went to Paris to study, leaving her family behind. When she gets there, she befriends a kind and pretty girl Marinette. They look a lot alike, too much in fact. When Melody realises that Marinette is closer to her than she thought, her whole life just became more hectic.......

This is an AU.
I own nothing except for the plot, Melody, the royal family and the Music Miraculous plus Kwamis.
