Since the video has now been posted
here, I guess it's appropriate to have a thread about the PV itself.
Visually, the PV looks very nice. Ayu's outfits in the PV are very elegant and feel almost "supernatural" (as I believe in Japan, people with flowing outfits are perceived to be such). In most of the video, Ayu's sitting on a chair and singing. I believe Ayu is covered in oil or tar when you see her laying on the ground, and she isn't laying on ice, but on feathers.
The lantern she holds in the video seems to be symbolic for something (perhaps to light her darkened path), but I can't make it out at the moment. Anyways, she comes across a room filled with flowers and children playing with dolls. For some reason, the kids keep breaking the dolls (another symbolic thing, I suppose).
I guess I need a bit more time in watching the PV, as I'm sure there's more to it than that.
