I believe the song is about a girl who has this emotional wall built up but really likes this guy, though she won't let anyone in. This guy really likes her and knows she likes him too somehow, and he's trying to prove to her just how much he really likes her and cares about her (: I could be wrong, but that's my situation and I found my ability to identify with the song as I listened to it. But if you think about it, that MIGHT be what the song could be about.
