Charlie Peterson is Hannah's boyfriend.
Charlie is a not-so-rich boy from Queens. When he was eighteen he moved to Brooklyn to pursue an acting career. He also goes to college, but it is not known where. Hannah gets into a relationship with him after they bump into each other (very cliche) on the street. He is shown to be a very normal boy with only a few friends. He is added to Chucks group of friends soon, but he is shown to not know what to do when they go to very high class parties or so. His relationship with Zach isn't very good, but that is evident due to their past with Hannah. He lives on the Upper West side now, and Hannah moves in with him there. In the flash-forward it is shown that he now is a successful actor and is still together with Hannah.
