I've watched this show up through Vol. 3 so far and this review is spot-on so far. This anime is produced in a style that excels at portraying relationships between the girls and slowly builds up tension and conflicts in everyday situations, and resolving them in a believable manner. I'm not really a classical music nut, but here classical music just...fits.

It's interesting that this hasn't been licensed in the US yet, considering how much interest there is in similar shows. (Anyone from Geneon paying attention?)
