The same way that I say people shouldn't try to force a dev to remove NTR content from their game just to please them, I also say that they shouldn't force a dev to put NTR content.
If later the dev feels different and wants to add NTR content, that will be another story and I would probably support them to do what would make them happy, but so far that doesn't seem to be the case with this game.
(if people don't like something, just don't play the game or ignore the content you don't like, if the game allows it. Criticism that can help build something better is fine, but don't try to force devs to your liking or send death threats because they are doing something you don't like. Go live your life somewhere else and let the devs be happy doing their things).
