I'll write a comment here to explain a bit more on the reasonings.
When I started developing this game months ago, I had no idea what NTR was, and didn't know it was one of the most disliked kinks too. After reading about it the first time, it said it was when a girlfriend or a wife was cheating on you. I guess I should have done more research but this is the information I got for it... So I never saw my game as being NTR because the "crush" of the MC is the one who gets taken. That is my bad, but I still won't change this, it's a key part of this game to drive the story forward and I'll stick with that, in the future when I'm better at everything, I could most likely make a update that makes paths to other choices to prevent this.
And the comment about Harem for this game, I see comments saying that the MC probably would not be able to start one or is too weak and pathetic, this is true. He is a 19 year old guy who just wanted to have some fun with his friends. This is update 0.1 which contains 1777 renders. 0.2 Will contain 1000+ renders, 0.3 will contain 1000+ renders... This will continue up to 1.0 which is the full release, if you don't think there will be any kinds of "Character Development" or "Time Skips", then I understand your reasoning for thinking this. But remember that the harem ending is in 1.0, so lots of stuff could have changed by then.
I'll update my itch.io page to show about the NTR to stop any confusion, but I don't have any power over this thread, that is up to thread owner. Adding tags or changing the developer notes and more.
Thanks for reading, and I do hope people give the game a try. As the NTR in this game is going to be small and also late into the game, can't really say exactly when because that would be huge spoilers. <3
