Also kinda tired of look at this family unit there's you your mother, FATHER, and sister.
And the father figure is only alive for SECONDS I want to be able to NTR our father.
The king, queen, and daughters are
unrelated to the MC. There is no incest in this game.
Maybe later the MC has a threesome with sisters or something and they do sexual things with each other, but I have my doubts. Even if that does come eventually, incest isn't in the game yet. Trying to force family ties between the MC and others doesn't even work with the game. The whole point is that the king potentially could marry off one of his daughters to the MC, placing him in a higher position of power and authority. Given the disposition of certain family members, that would cause civil war, not exactly and environment conducive to incestuous relations.
Also, the king is alive literally 8 of the 9 chapters in the game so far. That's not "SECONDS". So far, this game has no netori (unless you could the oldest daughter telling a prince in a foreign land to piss off, although that was before the game even started). The king was already cheating with the queen, so it wouldn't have been NTR anyway. He didn't care about her sexually anymore, so the MC would never have made him jealous. (Although the MC would've probably been killed or
at least imprisoned if the queen cheating with him became publicly known. But that would've only been to save face, not because the king actually cared.)
All other LIs either have never been married or are widows, and not one of them is in any relationship. There literally has been nobody for whom netori could apply.
