Well, this is the last page. No clue what's happening, but whatever. Also, I don't know what to put for the artist's name. I'm fairly sure there aren't any other works by the artist on Danbooru, but I could be wrong. I just put "mokolave" in the pool name because that's the pixiv thing. If anyone can clear this up for me, I would really appreciate it.
I looked at the pixiv page this was from, and I say the author is correct.
Also, it looks like the whole thing is 68 pages, and what's already posted here is a sample.
Given how old the sample is, I think the full doujinshi should have been scanned and uploaded somewhere by now, so I'm looking for that. Meanwhile, I did find this, so I may upload that here at some point.
EDIT: Praise be, the artist uploaded it themselves!

Could it be that...You wrote Shou a love letter?This can only mean that they can't be suspected anymore, I mean, well, it's the truth cuz the other 3 have alibis and all so,You bastard-!!!I'm not suggesting that it's true, but just in case ya know. Ah but I'm not suspecting Nazu-Nazu of anything ya know? But in this position, I had to hear everyone out and so it came to the conclusion that it was -not that I was targeting- Nazrin, to be one who did it but,
