That went way too fast. 
Did the author not get a contract for more than 2 volumes? Or didn't want to continue? Because this really had potential for a whole series. So many things happened in the second half all at once and then it just... ended. The epilogue was just suddenly there, a huge time jump with almost no explanation whatsoever.

I'm not even angry, just sad, because it's really good and had the potential. And there aren't enough queer horror stories.

Also, the art, especially the background, improved a lot. As the author mentioned in the afterword: they hired a background artist for volume 2, and you can really see the difference! Not that volume 1 was bad, but there's still some positive difference.

Even with the sad conclusion, I'd still recommend this short manga series to basically anyone who's up for some GL, slight horror, bit of yandere, or all of it.
