It's fairly obvious that Yuu and Miki are well suited, if not destined, for one another but even if the conclusion is known the path will be long and winding to get to that point. And, like much shoujo, the fun is as much in the detail and the travel as much as the conclusion. Much of the expression, even the actual cute value of the characters, is expressed in a sort of stylized way, almost like a shoujo manga. Once you become comfortable with the style it is very comfortable, and has some charm, but it's not initially very attractive. There's also lots of mechanisms, such as focus shots, symbols and still frames to comment on what is happening.
Action is minimal and tends to devolve into still frames quickly, which actually fits the style.
The voices are quite good and the music, while perhaps not too varied, is light and addictive. Other Reviews THEM review An excellent and in-depth review from THEM which seems to match my own feelings. Un-ashamedly shoujo and skilled production that some will love and some will detest. Anime Review review Always nice to see an entry from the Anime review, and the news here is positive. While he mentions he's only seen the first couple of hours he finds the series to be terribly involving and addictive right from the start.
