I think this song is about how you can not really know someone that well but still fall in love with the version of this person you made up in your head. Maybe this sounds kind of nuts to all of you, but I do it all the time. I only realise that I love this product of my imagination later, and then I start to "wonder if truly he is nearly as beautiful as I believe" and think that "I don't want to be fool-hearted".
