Oh come on! MC's dad is back in town and gets more action in five minutes than MC in the whole game (not really, but it very much feels that way). Ashley was by far the hottest girl I've seen in the game and then twenty seconds later I have to see that literal motherfucker getting his dirty paws on her! Why do that? Why show me a cake and then shit all over it?
This is why so many people, myself included, call stuff like that NTR: I couldn't care less about MC's in-world relationship to people, the moment you show me a hot girl that's obviously not just a random background character in a non-NTR game/path, she instantly becomes a LI for the PLAYER. The player's experience and feelings are what matters, not MC's, which is something that needs to find it's way into tags imho. Games like this cause serious emotional whiplash to people like me. And while I've learned to read the signals early on, I often can't stop myself from reading on, because I want to continue the story unless it's really bad. I really hope that one day soon we can have some tag for games with scenes like these. I agree that NTR is not technically correct and therefore another tag name needs to be found. Personally, I often just use "NTR-ish" or "NTR-related" in my notes.
I understand that there is no financial drive for such a tag, quite the opposite, but I also think that the almost constant turmoil that the missing of such a tag causes is not worth it.
