Well, I might be grossly misinterpreting something, but I'm about one hundred percent sure that this anime provides more of what I've definitely been missing from my anime lately:
Seriously though, what the hell! In this one, we've got a brother-sister relationship that is openly endorsed by their mother and sister.
Moving on! Animation is pretty (with the exception of some badly-integrated CG at the end), and generally pleasant to look at. Only one episode, so we're not exactly talking great character development, and it's actually all really pretty shallow. This is another show based off of a game, and it definitely exudes that particular quality (if you've watched a few based off dating sims or H-games, you know what I mean) that all shows of this genre give off.
The story is about a long distance relationship that is slowly breaking down over time, and some of the missteps they encounter along the way. Toss in some other characters to add to the confusion, and see if distance makes the heart grow fonder.
