Well, the idea is to have the NTR events happening in free roam events randomized. And you stopping them would need to find the girls first, but its mostly like a secondary thing, its still something like WARNING WARNING NTR, but you kinda need to find them first. The main thing will be the raid mechanics, which I will not share, but they will work similarly to "The perfect pair" game, but it won't be possible to reach all the sexy stuff in one raid, there will be corruption levels that will unlock different type of ntr for the main girls. There will be a stage where you can still stop the NTR fully, but if it goes over it, the girls will get corruption points which will lead to deeper NTR.
There will be 4 phases to a day cycle. First cycle you take a quest or decide what will you do, the second phase will be everybody working or doing stuff, the third stage will be people interacting with each other and girls being targeted by the antagonist and the forth stage is like corruption checker which leads to NTR scene that you can only find and view them.
With more corruption levels the girls will start doing lewd stuff on all the 4 day cycles. Plenty of stuff to add and do in long run, to make the NTR fans feel welcomed.
There is no plans on making NTR to be a bad results that would lead to bad ending and you needing to choose different choice.
And gameplay idea will be actually challenging and it will only trigger NTR chances after you take too long or do mistake 3 times. And its not shooting, quick time event or some button smashing.
