The first half of the show was very sweet, enjoyable and promising. It was surprisingly romantic and I very much enjoyed the chemistry between the two leads. In the show's second half, more and more supporting characters got crowded in, the main couple's focus became fuzzy and the story started to drift around and lose its purpose and became less interesting.
Looking back on the show as a whole there was a story they wanted to convey and I can understand it and its emotional core, but it's too bad the later episodes weren't written as well as the foremost.
I love the main couple's art and design, animation started out good bet went downhill later.
