Yuri-ism received a request for this title before but they refused cause 'diaper fetish'. A miss for them, almost a loss for us readers. Thank you, yuri-ism.
Well obviously, as you can tell by the comments, the the title doesn't reflect the content, and everyone thought it was gonna be some fucked up kink. If they had to base their decision on something, oh i dunno, the title maybe, I think their decision is understandable. It's not like they'd purchase the doujin and check juuust to make sure that surprisingly, the focus wasn't on diapers at all.
It's likely that the one who suggested the title had a similar assumption on what the contents would be. That it happened to be a rather nice, not-diaper-focused doujin doesn't mean that it was a good call on the suggester's part.
If they suggested it "cause diaper fetish", and it was refused, "cause diaper fetish", and it turned out to be a good read and not about that fetish, well, it really isn't Yuriism fault, nor something you can applause the suggester for.
I know they say don't judge a book by its cover, but with a title like this, surely it isn't a stretch to say that it was very misleading.
