Word to the wise: if you approach this "Furo Girl" with any lewd thoughts (like how you're gonna watch Sakurai Hinako taking bath after bath), you'll be deceived; there's nothing even remotely lewd in this dorama, and believe me, it's probably better like that (besides, the main character being such a monomaniac simpleton with the mind of a small kid, it would be impossible to see her under that guise anyway).
Unfortunately, you'll probably be deceived (at least, so was I!) even if you approach this expecting it to be quirky-but-funny: because, well, quirky it is, all right...but funny...hmmm...not really, sorry; a coupla faint smiles in 6 episodes is all it got out of me...:/
Cast-wise, Sakurai Hinako does ok, all things considered. The kouhai is as annoying as they come (anybody else would have blacklisted her after the 5th "Senpai! Kiite kudasai yo!"), but then again, if that's what the actress was going for, kudos to her as well.
The music is kinda ok, but personally I can't help but associating Beethoven's "Ode to Joy" with that bureaucratic, neo-sovietic nightmare (all imho) which is the European Union (which adopted that as its anthem, in case you don't know) and, well, that's ruined that piece for me, like, forever.
The only reason why I didn't drop this and kept watching it till the end is that here and there it provides the viewers with some interesting and creative info/tip on bathing and, more generally, on "home ec" stuff like how to make inexpensive and environmentally-friendly cleaning products with baking soda and citric acid, and so on.
All in all, not enough to reach the passing grade, as far as I'm concerned. Not even close, alas.../.__.\
