lol. Just saw it and I gotta say, this is why I love Ayumi.

She can never just let things be happy. Even her happiest of happy sounding songs have to have some kind of sadness about them.
I really liked the PV, though not as much as Alterna and I'm still not sure if this video should have cost as much as it did.(although it does look great.)
Also, yes the PV was a lot of dancing and looking pretty, but in the second half of the song, when the house burns down it becomes more serious.
