First The teach having sex with principal is really not ntr as Mc don't have any sort of feelings for her and then they have this kinda relationship before the Mc cough them (not all girl wait mc with a spread legs) and second what's the dev mean for ntr is avoidable is for other main girls : the risk of getting rapes( till now only ruby) , or Mc set them for money or maybe in future update save luna from gentleman club patron(brothel), the game is nice and if the ntr is justified and not the solit "u have much big cock more the my bf let's fuck" I don't think it's big deal to see 1 or 2 not give their holes to Mc, and for the people don't have tried yet coz there's some ntr, give it a fair shoot and try this game
As I said before, you completely totally missed the bloody point.
The Dev calls that first blowjob and dicking the teacher gets right off the bat NTR! But you can "avoid" this "NTR" by looking away!
In game box: Do you watch? (NTR) or Turn your head away? (No NTR)
It's clear the MC does have a thing for Luna, even before the start of the game. He wants to get with her. If she was a nobody to him, he wouldn't have cared that she was carrying condoms. He wants her to stop getting dicked by other guys. Your only option to get with her is to earn 1k and fuck her as a client. At this point, this is nothing less than Unavoidable Netorare, but clearly the Dev doesn't think it's NTR because you aren't there to witness her getting dicked by others.
The Dev seems to subscribe to this: "If you ain't watching it, it ain't NTR."
Oh, and by the way, the quest to knock out the B so he can dick her, is NTR as well, just a different perspective. Sure, you can simply choose not to do it, and have it glare at you the entire game. If a player is anti-NTR, they should be able to drop that quest before reaching the point of no return.
I said this 3 times, if you were ever going to understand you would have by now. I guess my only option is to block/ignore you. Don't even know why I bothered to reply to you this time.
