The art was good and I liked the style that the characters were drawn in. It wasn't overtly shojo, with the obnoxious proportions and eyes, and no one seemed too over the top, which works considering that it is a simple high school love story.
In general I really enjoyed this anime. The only thing about it that I didn't really care for was the ending. It didn't really tie up all the loose ends that I was expecting and the OVA was random and didn't give me anything extra to add to the actual story either. I think a second season would be a great way to fix that problem, and give the viewer more insight to what really happens after the end of this show.
