Lol the overview actually does sounds like a cuck game set-up .I thought I was the only one . Atleast dev put the NTR warning in the first release itself so you know what you are getting into.
also the femdom and blackmail tag to go with it.

After trying it, in addition to the fact that they kill the only girl the MC has had sex with during the game to blackmail him (which made me directly close the game to possibly not return), it seems, due to the variables, that you are either trying to have a relationship with all the LIs or you will end up having NTR, since you either gain points with them or you gain NTR points, which, if there is no harem ending, will possibly make the game hell in the end if you go for all the LIs. So it would be interesting to know if the game is going to be a harem or not.
On the other hand, if a LI doesn't interest me, because, for example, she has femdom, and therefore ends up having NTR scenes by avoiding giving her points, then I will have done well to leave the game. Personally I think NTR should be avoided by having a button at the beginning of the game that makes him outright non-existent for those who don't like it.
