I was a bit disappointed in both the PV and song.
The song I thought was pretty good. I just felt that the chorus could have been stronger; and by stronger I mean that there should have been something in it to make stand out more from the rest of the song. Sorta like (don't)leave me alone, for a comparison. So it was good, I just wish there was more oomph in the chorus.
As for the PV, I was just a little...confused, is probably the best word. I was a bit weirded out by the horses (though I understand they're supposed to be the chess pieces from Alice in Wonderland), and the timing of some of the lyrics to the images was a little...uh...weird, I guess, for lack of a better word. And the dancing was rather lackluster for her abilities, I think. Also, someone mentioned this before, but her hairstyle is very similar to Ayu's 'Because of you' one, and her clothing mimics Ayu's, as well. I'm not saying she IS mimicking Ayu, just that they're similar and that's that. Just an observation.
