That depends of which ntr you dislike, sorry.
You could find groped, slutty situations and some things like that in the no-NTR route. Aside that, if you follow the hearts option you can avoid the hard NTR.
I told you this because I found diferent people who have diferent levels of dislike about that.
If you don't like to watch the girl with doubts or being teased foe other guys I recommend you not to play.
Thanks for your comment and let me know if I can help you with something more.
