Well, I've just finished reading the contents of the update and I've read the last few pages of comments and for once, I'm adding my opinion, because, the discussion about the NTR looks civilized and, it's nice.
Personally, I don't mind the NTR, for example, I love “Long Story Short”, which would be pointless (for me) without it. But I'm not obsessed with that, what interests me is characters with a minimum of personality and consistent behavior, and if that requires NTR to justify it, no problem.
In this, Rin is in the continuity of her character, going into every possible fetishism, my problem is that she's only defined by this and that it becomes her only interest...
For me (it's just my opinion), the NTR is anecdotal, the problem is that the author doesn't really know where he's going with his story, and in the meantime, he fills in the gaps with Rin to keep his audience interested. Easier and quicker to do than to continue developing Lin and Annie's story, for example, I've come to wonder what other new fetishes of Rin we're going to get in future updates rather than the continuation of the story.
But I understand the anti-NTR stance in this case, even if it's avoidable... there's a problem
