(Of course, Hisao/Hanako was always my favorite couple, so anything that attempts to continue/fix her Bad End is great in my book). Still, a very enjoyable and good read. It kept the spirit of the characters very well, which I like.
The only (and I seriously mean ONLY) minor nitpick I have is this:
Someone was playing classical music in the background? Wow, that does sound awkward indeed. XDFor several awkward minuets neither of us spoke.
