The poor dear.
Not only is she sick with this epidemic influenza, but with her running a fever there's no telling how many parents/nurses/doctors must have put a hand to her forehead, which I am sure also embarrassed her to no end.
(She is, for some unexplained reason, VERY self-conscious about anyone so much as catching a glimpse of her forehead, you know.)
Got the same impression. Hopefully the studio version is much better and end up liking the song. I would like for Berryz to try more j-rockish songs, to fill up the void left by Buono's inactivity, and I truly think this type of songs fit Berryz the most.
