Having read a bit of the WN Fan translation, this story made me ask: *What if shojou protagonists actually created clouds of powdered sugar when they reached critical levels of romantic cuteness?
Seriously, though, I think this story consists of 30 times the recommended daily serving of sugar per chapter and nothing else.
The biggest problem I can see is that apparently the fan translation is already approved by the author, so people might be upset if it's shut down in favor of an official release. Or it might become another Rokujouma, but that means it would be less viable commercially.
To be fair, those two are relatively unknown series whereas Expelled From Paradise, IIRC, had a bit of advertising when it was released a few years ago, has mecha and more importantly, fanservice.
@Char663 22 if you include the short stories volume 4.5 (which in turn was comprised of a selection of the stories in the 3 Ex volumes which were released with the anime)
It's also finished. But then it has finished three times now so that doesn't mean anything.
