You are absolutely right, it COULD happen So far.
Yoon was only offered the "free pass". She has not yet accepted it. She first went to her friend after an argument, she hasn't spoken to daniel since. Now, of course, we could still discuss: is a "free pass" only valid if accepted or already with the offer? I'm currently not 100% sure about that either.
There's actually is cheating in this game. At the moment it is not in the form of NTR, but that could still happen as soon as my mentioned requirement 3 is met
Examples:
Yoon has already cheaten on Daniel with a Zoe at the party, if we habe chosen so. There will definitely be more in the future. definitely not just with Zoe. We'll see where it goes.
Josef and Michelle can be played in such a way that they are not faithful to each other. Joseph is also interested in Yoon. This story, too, could theoretically lead to another "free pass", cheating and NTR as well. Yoon could steal Joseph from Michelle, Michelle could also enjoy someone else , maybe Yoon. I already said, NTR is not exclusive to the MC, anyone can do it.
Jasmine is cheating on her husband. Nor is that an NTR either. Because we don't know several things: maybe there is an open relationship there? And do Jasmine's affairs have a negative impact on your relationship? These questions are still unanswered.
So yes, there is already cheating in this game. That's why the game is taged this way. But as I said, cheating is not necessarily the same as NTR.
Since there is a "free pass", there will be an open relationship, this leads to sharing content in the future. So in theory a lot is possible. However, the developer always emphasized that nobody will be injured in this game. So I have my doubts whether we will really see completed NTR. I personally wouldn't mind that. Anyone who knows me here knows that NTR is one of my fetishes. Not because of the fetish itself, but because of the many great stories on which it can be built. A lot is possible there that is simply not possible with romantic relationships. We also get to see so many different sex partners here, men and women. And my wife would prefer to see men!
