This one was the hardest one to get through so far. It was so mind-numbingly boring that I had to take breaks and switch to other books in between. I think it's the Prince Ten-yuu plot, I honestly just couldn't care less about him. He was entirely uninteresting and took up 70% of the book for doing absolutely nothing. Luckily, the short stories at the end made up for my frustrations but it definitely wasn't enough.
