You're incorrect, but I believe you genuinely think that and aren't bullshitting me given the circumstances.
Allow me to explain.
The Artist for example is the most not evil looking Other. If you don't dive too deep, anyone would believe you try to portray the Other's as neutrally as you can. If you actually follow the red head's storyline however, you learn she is little more than his puppet, and he is planning to drag the entire town (your Uncle probably included) into his dimension against their will. If you try to stop it but don't want to kill her, the Artist tries to kill you through her meaning you have no choice. This is the least evil Other we come across, and he's still completely evil. From the framing and wording you didn't mean for it to come across this way, but there is no other logical conclusion.
Which means you have issues with trying to stay neutral even if you want to. Some part of you wants to write this way, and ends up slipping stuff like this in.
Which is why for Hana's case I genuinely do believe you accidently wrote NTR. I've provided the site definition, examples, and a explanation down below so you can see what I'm seeing.

Some notable examples are the following.
Needless to say the last one should have been a part of the FIRST vision, so we know she isn't a real love interest. With it being the last, along with everything else, you've accidently waded deep into NTR territory.
It isn't too surprising this has happened given your other writing tendencies and the fact the game has been in development for 4 years. You forget things, your opinions change, and the story suffers as a consequence, which is true for all writers.
You can pretty easily fix this issue by simple moving Mother's comment to the first vision, or re-writing Hana's dialogue and interactions early on so it's obvious she's a slut. Alternatives are removing NTR side of her sluttyness (there were other comments she made that did not follow the above vein, like really wanting to be raped for some reason). Branching paths. Working with the Trinity to spank Mother into being monogamous so Hana is, or just flat out kicking Mother out of the realm/killing her to free Hana from her influence.
You have a lot of options but if you continue down the current course, the game will get tagged with NTR, and you will continue to rub people the wrong way, leading to less support as at first glance it does look malicious.
Regardless of which path you pick I won't be playing anymore unless there's a non-sharing path because I don't tolerate any degree of sharing.
PS. I assume I missed a lot of scenes due to not buffing my non-combat stats? I noticed buffing perception allowed me to see more hidden items. If so, a note at the start of the game would help immensely.
