Honestly, I get what you mean. I prefer games with both routes and preferably with a decent amount of both types of scenes. I play a stupid amount of NTR and don't care for what perspective MC, Fem MC or Bull. But there are plenty of good non-NTR games which are good.
Sure, NTR games get mass-produced with decent quality, but It's like eating the same food over and over again. you just get tired of it at some point.
The story of this game was okay in my eyes, but its execution was just horrible. There were a lot of features I felt were missing, and it felt like everything was rushed near the end. I wouldn't be surprised if more were planned or if I'm just missing content because there were a few empty rooms and areas that I haven't really seen be used.
If you're looking for fapping material I'm sure you know that there are better NTR and non-NTR games out there
