Because once there was a reason here that DC is planning to change the story of Eric and ms Johnson.Why? I don't see any indication why that has to or should happen. Eve is badly in love with MC, why on earth would she share him or fuck somebody else herself? I mean, it's fine if that's your opinion and your taste, but it's not like that's universal.
As far as I remember, DC's argument was that he didn't like MC lying to his friend.
The usual logic is that if MC does not have the consent of his "girlfriends" to fuck other women, then his every relationship with another woman after getting a girl will be cheating on her.
I assume DC does not want such hypocrisy in the SS if it is to be a light and pleasant game.
Definitely a better idea is simply to write a story in which he has permission to fuck other women.
In addition, there were leaks that the beach house MC would have a small harem.
If this turns out to be true then all his "girlfriends" should have the option where they allow MC to have sex with other women.
You can pretend that none of the women / girls know anything about other women in MC's life, but it would be very amateur behavior of the creators since in the MC game he doesn't behave as if he wanted to keep his relationship secret.
Personally, I think that all these pregnancies are not an impregnation fetish, but DC's way of adding to the SS the universal acceptance of MC women to share it with other women.
Simply in the MC game will ultimately guarantee women healthy child.
And most women want to have children sooner or later.
