I can complaint when I see something that doesn't fit a character shown in the game. If I see a shy type of character, having an orgy in the next version I can express my complaint, or has this become an only good job dev post allowed?
If I see the way a character, the MC, is not fitting a future path, NTR, then I can express my complaint, I am even stating my points logically, not saying it doesn't match because I don't like NTR or things like that.
Characters in games, novels and all kind of stories should be consistent, coherent and believable, and in porn games there are some kinks that works in some characters and others that don't, in this case NTR doesn't fit the MC. ANd I say so far, because it's the only think we know about the MC, and instead of saying I think he should do this or that, I base my reply in what has been shown in the game, because as a player that's what I got, nothing more nothing less.
Also harem and polyamorous are different kinks. In harem the girls or boys are in love with one person, the MC, while in poly they love the MC and each other, it isn't the same.
So I just complaint because I see that path as a plothole that doesn't match with was has been shown of the character so far, same as dev saying that Rachel didn't cheat but seeing that cg makes you think otherwise.
