I love this song, I think it's about a guy who loves a girl, and can't get her out of his mind, but can't really tell her how he feels, and he's diccided to try and tell her anyway. But it could be something completely different, it's depends on what situation you're in, and how you feel about that! I really love this song, and I've put it on my mobile phone, so I listen to it every day.
