You want to know the difference between her and other girls? She smiles even though she's going through a rough time. She has the most fun with her friends. She puts everyone's happiness before hers, she's not afraid to be herself. When she looks in the mirror, she doesn't see a pretty, hot, sexy, etc. girl. She sees a beautiful girl who has yet to find her place in this world and she lights the whole room up whenever she steps in. That's what made him fall for her in the first place.
