Only 3 out of 5 chapters was scanlated by Sling, so chapter 2 and 5 are missing.

It has a rather weird concept and really doesn't seem to go anywhere but for whatever reason I liked it and would have wanted to at least read the last chapter (despite it being axed). I actually don't know a lot of loser MC manga in which the MC somehow stays a loser with the exception from some smut, adult thingy with lots of cheating or NTR in it. That might however be one of the reasons why not so many seem to enjoy this. I'll try to look for the raws of chapter 2 and the last one at least
Edit: Managed to find chapter 2 but nothing else

I can't link drop, but the entire series is findable if you look up MONOクロ (the japanese name). No usernames or passwords needed either, since this is technically not hentai (no visible copulation) but its definitely NSFW.

There are 6 chapters in total.

Damn. How pitiful it must be to get cucked by your own body
