Just finished it... loved the ending!!! I was worried that they were going to drop the ball or something at the end, but it was a beautiful ending. Despite it [the ending] being somewhat predictable, it was extremely satisfying, to say the least, to see all the tension resolved. I will probably write a detailed review later, but here's the bottom line: this show is excellent, from start to finish!
What an ending for Kou and Aoba!
