The form of the video, in my mind, begins as an admittance of it's being. That is a wordy way of saying it knows it's a music video, nothing more spectacular than that. As it begins it's about the music (as most good music videos should be [unless it's a radiohead video, because those are almost always great and don't make any sense at all, much less as a vehicle for the music]). But as the video progresses we see that it has a lot of story, which is heavily important to the song. The spectacle moves away from the playing of instruments, though not completely lost (and for the better I think, 'cause damn, those kids can play), and into the fairy tale world. And as we delve deeper and deeper into the world, we see that the song isn't about the man like the words woudl superficially suggest, but about the woman. It's the woman's love song to her secret lover.
I feel that this is expressed by my focusing on the music at first, moving past the music to it being a story, then within the story focusing on the woman. The song and the video do not overtly explain my conclusion of it being the woman's song, but they subtly hint at it more and more as the video progresses, as I did with my 300 words.
