Juliet is the perfect daughter to her cold parents. She's devoted to her magic studies, studious and serious, and she even spends her weekends at home.
If she's a little lonely, well, that hardly matters.
Romeo writes poems, collects fancy pens, makes wine, and is, according to everyone who cares about him, a romantic disaster. He does his best to ignore their knowing looks and disregard their entirely-too-practical advice.
Juliet hates the upstart, uncivilized Montagues because they're her family's enemies. Romeo does his best not to think about the wretched and pompous Capulets because he doesn't need that kind of negativity in his life.
But then one morning they wake up in each other's bodies, and everything changes.
