The PV is really fantastic. I think the reason why I liked it a lot because it felt so much like the older Ayu... no dramatic facial expressions or crying... no overload of her dancers (none here actually)... there's something very simple in the midst of the confusion that goes in the PV. I like how there's only Ayu in the whole video... it's really nostalgic.
EDIT: one thing that bugged me though. the little "jewels" she has all over her body made her look more oily than sparkly.
