I think most of us play this for Melinda. That the rest of the girls fuck with one or the other gives us a little the same. And now I think the dev had a bad idea putting Melinda's ntr in with the MC. The situation of Sundays being blackmailed now has to have a continuation, because although the logical thing is that we kill the blackmailer, if you do not do it, it has to follow the story and in a game that was more or less vanilla and harem is getting into the swampy waters of the ntr when there was no need. I hope this decision does not have a negative impact on the followers of the game. I think that when the ntr starts, even if it's optional, it turns the game into something darker and I don't think were the better for some game like this.
It is only my opinion, obviously
