Found this a while back. as far as I can tell it is not on here currently (and is particularly difficult to find)

I have no idea who published this (and feel free to comment if you know)
I hypothesize that this may have been a DA and/or Tumblr artist that has since been deleted

I am also unsure if this is translated (although the title I found it under suggests it may have been, but I do not actually know)(nor do I know if such a translation was the official version of not)
(found as Modern teaching / Moderner Untericht (Unterricht))

I also do not have page 1 or the cover page

If anyone can find a more complete and/or higher quality version of this feel free to replace and expunge this one. but I've not since been able to.

Alright so with @atasitian's comment I did a little digging about michel69890 on deviantart. and with a few leaps this is Hanging 101, by Möbius or mobius. and is for sale along with others on his gumroad page.

(oops, but I have no way of deleting this etc so it's here unless it gets expunged or deleted now)
he may also have a dolcettish account. but that website appears to need a registration to determine that and I am not registered with it.

This may have been posted by "michel69890" on deviantart, who may have copied it from a site called dolcettish. At least that's what I get from a quick search.

His stories are way overpriced, over 10 bucks for 20 pages of content.
