Mia Grace Jenner is Marianas Trench's devoted manager and co-songwriter since day 1. After they finish writing their newest album, Astoria, Josh and Mia realize their sexual tension they've been holding against each other for the past few months. They both want to see where this relationship will go, and they do. Unfortunately, Mia has to watch out because if she falls too deep in love and Josh doesn't, her anxiety will start up again like it previously has with ex-boyfriends. (Josh is aware of this, by the way) Mia just doesn't want to be a Cry Baby anymore.
