This manga's story ended with chapter 36. Everything had come full circle, the characters had completed their arcs, etc. Then the mangaka for some reason kept it going, but made the baffling decision to do so by effectively warping it into a completely different manga, nigh unrecognizable from what it had been up to this point. And now they're suddenly trying to bring everything back to earth for a second ending? I can only hope that they realized that, if they wanted to now make a surrealist ecchi comedy, they should make a new manga for that instead of taking what they had made and turning it into... whatever this has been.
There's nothing wrong with liking what's been done since chapter 36, but it would be better for everyone if it was its own manga instead of the bizarre tail-end of something that already finished.
