I remember that one article had a pretty good ending. It should be this one. I also got to know the author from this article. If only he had been born a few years earlier.
Each ending is more sad than the last. I seem to have only read three of them and one more. I will try to finish it as soon as possible. This ending is a bit regretful.
This is the teacher's first work. I haven't read it yet and I'm really looking forward to it. The ending is pretty good [Blue Heart]. I'll revise it after reading it. It's really nice.
