Its not just about hating NTR, its also about lamenting the resources that are being wasted creating an H-scene with a girl NOT with the MC, if its not an NTR game, then animating other couples seems unnecessary. I prefer all the time and resources be devoted to the MC with the girls.
Besides, why is there a girl in any game that is not going to be a Li anyway? if you are trying to build a world, sure, some random here and there, but to go as far as to create an H-scene without the MC? it seems far too much of a waste.
Because there is also some people who has a fetish for "spying" on others and they would need H-scene ?
In the end it is just my opinion about the subject nothing more. I am not in to the fetish myself but I can see "a" reason why it was added beside world building.
say ... you sit in you room across the street with a spy glass trained on the neighbor's room.
The girl your age next door is in a lesbian relationship and is having sex with her girlfriend.
They will never be in a relationship with you
1) because they are in a relationship with each other
2) because they do not like men
3) you are a man in the game who like to watch others have sex
To put it simply Voyeurism is a fetish that people also enjoy.
and seems to be needed as a tag for this game, for those who does not like it can avoid it and those who want it can find it.
For me.... I am of the opinion that all fetish are welcome in a game and that every sex scene in should be skippable, No matter how vanila, So those who is not into them can avoid them.
Thought I do not mean it as they would still talk about it as it happens, but rather as it never happen in the first place
in the end it is up to you
If You feel the game waste too much time on something you do not like.
Then to not play the game it is quite simple.
