Appearances can be deceiving

GEEK - NERD - MYSTERIOUS - WEIRDO - STRANGE

These are names Quentin has been called in highschool. What they don't know is that behind all that geekiness and nerdiness, there's a thoughtful, selfless person who is just trying to get his best friend back.
Margo has been a mystery to Quentin since she stopped talking to him, but there's nothing he likes more than solving them. So when she shows up in his window pane after a few years, asking strange question to just disappear the next day, he takes it to heart to find her and bring the girl he once knew back home.

People label you, that's a hard truth. Sometimes you can choose whether you want to give them what you want them to think and say about you, or you can chose to let them think whatever they want. Margo chose to let Q decide whether he is up for the challenge or if he is just going to let her be labeled as a crazy person and disappear forever.
