Yes, Ocean knows what NTR means unlike some other devs. And that is why I stated there will be no "hard" NTR unless the MC invites it with being an ass all the time. Ocean will never make a NTR scene out of the blue, for NTR´s sake. We have more than one game on F95 where something like this happens, NTR without any prior events leading to it.
In WIAB the MC and lady in question need to treat each other badly and/or cheat and lie for a "real" NTR scene to happen. You will know why you encounter such a situation, not as in some other games where everything is sunshine and suddenly bang.
If the MC and the lady in question do not treat each other shabby and stuff, NTR scenes will be more netorase,sharing or swinging, depending on the circumstances.
I dont know what ocean has planned in the story or how he thinks but I can see in post that he knows what ntr means and the things you describe beaing a ass/ignoring girls/dont care for them/only sees them as sex partners no feelings/ending relationships(as a consequence of mass cheating harem fantasy or beaing a ass) or sharing/swinging is not ntr so for this things he dont need a ntr gallery or a ntr tag.
ntr can only work if mc has a strong conecction/feelings and relationship build up and care for the person otherwise its not ntr.
and on top of that this is a post form Ranting Old Man he describes it very good Iam not so good at english
„ If you aren't trying too or if you don't feel the emotions that NTR are meant to trigger then I hate to break it to you. You aren't into NTR.
It's literally that simple. Often times I read, "well i like watching the corruption of someone innocent or pure" Well that isn't NTR, you don't actually need any of that for NTR.
Others say, "Well I like the Domination part of it." Again Not NTR.
Some people like cheating or make him cuckold. This isn't NTR! You can have all of that and it still not be NTR.
NTR is literally an emotional struggle. It's the thoughts of the fmc as she's being tempted by an antagonist and is trying to stay it straight, it's the anxiety the mc gets when he's starting to figure out what's going on, it's the heart acke when he catches her in the act. It's the humiliation, resentment, anger and frustration he feels. It's the jealousy he feels. “
so in short ntr is particular about EMOTIONS that only work with good writting and realationship build up with a person you love and care about more than your life and a antagonist that ends your relationship/steal her.
