Haha, it's actually one of my favourite scenes in the PV! (next to the one where she pseudo-rips her coat at the glass breaking sound!) JUST LOVE watching Ayu look and go INSANE!
As in, seriously, I think she does A REALLY REALLY GOOD JOB of looking deranged, psychedelic and maniacal, yet retaining her pose and elegance! She's psychotic, yet she plays it well! Got to love her!
Seriously! The more I watch the PV, the more I love it!
