I'm quite neutral on NTR, however for it to be NTR it should be the MC's girlfriend or something like that, for me this is just a storyline, bad things are happening around you and what will you do?, stop them?, ignore them? try to profit from it?.
Sometimes you can be helpless, others you can stop things from happening and many times you can only have an influence on it. If something is unavoidable I just hope to get revenge in the future, making a character disappear, killing him slowly... it's funny to play but... not so much if you just want porn.
I like to have a bad beginning and starting to change things around you, but without being so MC centered... personally I just hope that the MC isn't the center of the world and that things just happen. Most games want to give the player full control over what happens but the bad thing is that everything else feels frozen because it needs the player to initiate any storyline or event. For me that's kind of boring.
