Thanks, but I’ve already read the sequel, and didn’t like it much either.

In fact, pretty much the first thing I did after the shit ending of the anime was to track down the manga in the hope that there was more. But nope - the manga has the same shit ending. But it does have a sequel. But Hanabi doesn’t fare much better in the sequel than she did in the original. Even the slut still gets a better ending than she does.
