Judging by the name of the dev i guess Is an ntr game?
Yes, without a doubt this game is going to have ntr, it is even going to focus on this, the same description makes it clear when mentioning that "But there are will be many who will try to fulfill their needs also. So, you better keep an eye on her!", basically another ntr where the son should be taking care of the mother more time than enjoying her.
At least make the point clear from the beginning, if you like the theme play it and if not just ignore it, very simple.
