That was a disappointing ending, in my view. :( Everything just seemed to patched together at the end. And the hopeless romantic side of me wanted to see at the very least, one last kiss between Chiaki and Nodame.
Oh well, let's hope the side story helps flesh out things a bit more.
At the moment, I have it rated 8/10. But for some reason, the last few chapters makes me want to drop it to a 7. We'll see how I feel about it in a few days.
