Interesting, correct me if I'm wrong, but after reading some comments it seems that this game does not focus on ntr, it is rather a means to justify an end, that is, the MC's wife is forced to please the prince (avoidable as far as I read ), and the MC decides to take revenge on him by becoming strong...
1.- First, it's good to finally see a MC who seeks revenge after an ntr, even though he could avoid it, there should be more like that.
2.- In this case it seems to me that the MC will become stronger and seek revenge from the prince, and based on this I could assume that it will be the MC who in the end enjoys the girls more, including those of the prince (if at all is there a mother, sister girlfriend ... etc.)
I'll give it a chance, I don't mind the ntr as long as the MC can use that to improve and then he is the one who dominates the situation, and, of course, if there are few scenes.
.
However if in the ends up having "paths", or focusing on the MC losing his girls, I'll just drop it.
Good luck Dev.
