Umm , is NTR avoidable?
As the top of the page says : NTR (netorare) content is present but can be completely avoided depending on your decisions. So, yes, it can be avoided depending on the choices you make later on in the story.
If you just read, yk? You can't be illiterate, I hope? How are you expected to play a VN if you can't understand English? T^T
