I am not going to discuss if it is ntr or not, my point is that in the harem version the difference is that you do not see what is happening but there are things that are evident that happen behind the scenes. A clear example is the case of Nena. We don't see her fucking Ajay but I think it's evident that this is happening from Nena's conversation with the mc thanking him for getting her to have a good cock. It really is the easy way to turn an ntr or voyeur game, whatever you want to call it, into a harem game. Delete certain scenes and parts of conversations. there is really nothing implemented in the harem part
