Just now watched it. Mitsui was actually pretty I think. And I think that I would've also preferred a dance shot, but whatever. I hate that this song's starting to grow on me 
tsunku: "Fanboys want touching, right?"
random-business-associate: "Well, melodies didn't do so well-"
tsunku: "NONSENSE! LET'S JUST THROW THEM RUBBING ALL OVER EACH OTHER AND--"
random-business-associate: "Don't tell me, put NUDE in the title?"
tsunku: "We're on the same wavelength here man!"
random-business-associate: ".. I think you left your line of coke on the table."
tsunku: "NONSENSE! That's for, er, decoration!"
lolol that would explain everything!

funny sh1t!
And why do you hate the song growing up on you? It's nothing to hate! the song is totally ass-kicking!
And now my perceptions about the PV:
First time I watched I was kind of dissapointed half way of the video, specially since the dancing was so great on the utaban performance, but the girl touching got my attention
Then I watched it a couple more times and I like it, it has low budget but it has a better camera work than previous PVs, shows some reeeeally nice closeups. Did you notice that sayu touching the bed is really... suggesting??
Also all the girls look beautiful in it (and absolutely HOT!), and Takkity ownz!
Groping and self touching FTW!
Cool PV after all, I was just expecting a bit too much I guess. I think this song is much better appreciated with live performances, and I can't wait for more of those, this weekend we shall get the H!M one, and next week popjam... I can't wait!!
