Oh no...
Portraying rape/pedophelia/child abuse is of course not a problem, but romantisizing them? That's a line that mustnot be crossed.
I don't think being a story can give it a pass. This story is very realistic, everything about it is so, then if the author just go and make them a couple... Jikes.
Other works being shitty, doesnt mean this is not, well, the same (if Jinno and Kousaka do end up together in that fluffy happily ever after way). Ppl are allowed to criticize what they've read, however niche. Sidenote, I mean yea it's a "niche yuri", but we've already got over hundred views on it.
Anw, I still hope the author doesnt avoid the problem and make this some mindless exploitation. Everything it needs is a reasonable ending. Welp, looks like Jinno won't open up to anyone except Kousaka now though.
