All of the stuff you describe, though, is avoidable. Rin only pisses if you either keep going (much earlier in the game) when she warns the MC that she's going to pee herself, and then if you allow her to piss in this update (rather than telling her it's something she shouldn't do). This latter thing is because she's not thinking clearly; something with the MC's power (at least, as far as we know) isn't working the way it's supposed to. But you can still avoid that by telling Rin no when she asks.
There is no netorare in the game; I don't know why people keep bringing that up. However, I understand the dislike of the gloryhole stuff and swinging. But again, that's is avoidable, so you don't have to see it if you don't choose things that lead you down that path.
Rin's clearly acting out of character with this latest, wanting to do stuff that shows less and less good judgement. She's not always been the wisest, but she's ridiculously careless in this update, meaning she's not her normal self. So you can keep her from doing any of the stuff you don't want in this latest by just telling her no. (The exception is the pet play, which will exist in some fashion, but which you can prevent from going too extreme.) Saying no to her when she wants to piss in front of people, for example, doesn't hurt her relationship with the MC. In fact, she might even thank him for stopping her (she does at least when he says no to the gloryhole).
There is no ntr: For now, no one knows whether this will happen or not, even the developer don't know
..
I'm saying this because, now swinging, no one knows what's coming next (maybe sharing, but of course, it will be optional
).
It's optional: You know, this is just the beginning. Once you start bringing this into the story, you can't drop it in the middle. It means you’ll need more content for satisfying others.
I'm asking again, why add this content now? It's not like the game lacks enough sex/fetish contents, right?
then, why are you introducing it now instead of during the past five years?
Most importantly, there are no planned tags, and there was no mention that this would happen here or any other platforms.
This is a perfect example of why you shouldn't trust games like this, even if the game is 5 years old. After seeing this kind of attempt, there's no reason to trust it.
Personally, I don't engage with this type of content (swinging/sharing, or whatever you prefer to call it in terms of tags), even though it's optional.
Her character has already been ruined by introducing this nonsense. Now, she's no longer a love interest, but just someone of lesser interest.
So, can I permanently avoid this character (Rin)?
Because if I want to play this game, this is the only option I have now.
That's my point of view. If I want to watch random sex, there are tons of websites for that, and I'm sure I'm not the only one who feels this way.
And hey, this is a pirate site, not a developer's den. I’m just sharing my thoughts on how I’m seeing her as a character after this content, and there’s no need for us to argue or fight over it.
