No there is of course no NTR becauseevery girl that enters his harem is going to be a full blown yandere that wants to get in his pants(especially the first two girls(they pretty join forces later on to try to drive away every other girl that comes to like him- though they are pretty reluctant to team up at first) all the while the MC will just be dense and oblivious to all of it, the only thing that this story really has a lot of is tragedy, heart-breaking moments, yandere moments and tons of point of view changes though the MC still stays as the main point of view obviously.
