It's good that you specify that "You" don't consider it NTR, in any case it doesn't stop it from being NTR, it's not a matter of perception, I literally specified it in the message, it's a matter of the type of game it is, obviously everyone who plays it knows what they're going for and knows which characters are targets, so yes, it's NTR, the type of NTR where you see how someone else gets the girl, in this case, it's the player who witnesses it.
Nobody who doesn't like NTR confuses "plain ol' cheating and ntr", Ntr is ntr, there's nothing to confuse and those who don't enjoy that genre know it, nobody is judging you for liking NTR, everyone has their preferences, saying that everyone is confused won't magically make them like NTR.
