The seeming wilful density of the people you're replying to is starting to feel like thread derailment to me.How is him fucking others not the point. Your response to a post stating NTR can be turned off was there's no game if you do that "Yeah you can do that but then you dont have a game. MC is designed as a spineless cuck that will be dominated. Majority of the content is for that.". Your point was literally that turning NTR of means there's not a game because that's the majority of the content. Turning NTR on or off does not remove scenes with Rowan interacting with the twins it removes the NTR.
That aside he does act against them yeah. Of the top of my head he can fight Andras when Andras says his going to fuck Alexia (result dependent on stats) can turn Shaya and Clihona to his side and can undermine the twins with his actions during Rastedel (Werden and Patricia) and the Orciad (Tarish or Delane) Rowan can go against the twins and undermine them. They have his wife and he'd get squashed in a head to head confrontation. That's the hold they have he can't get Alexia off them without him or her been killed or go get help without her been killed, once the amulet went on he can't even attempt it. He is not Goku a power up isn't falling from the sky that'll let him suddenly smash them so he has to work against them in other ways. Rowan isn't in charge but he isn't submissive, coward or a cuck unless you make him so.
The most recent update the changes in the opening made him more aggressive towards them and fighting them doing well, that's not something a change a game intent on making the MC a cowardly sissified cuck does this late on.
As has been said, one can avoid every single sexscene including the twins and Rowan being bossed around and threatened to do their bidding does not in any way constitute 'NTR'.
A360, one could also mention how Rowan can help Heleyna, how he tries turn one of the maids to spy on the twins (very unsuccessfully), random events around the castle where for example you can divert supplies to dangerous routes so they are lost (could perhaps do with some more direct reflection ingame), the many many random events on the travel map where we can be good people.
Rowan is only a spineless coward if played as such.
At some point it sounds essentially like complaining that this isn't a completely different game, goodhearted vanilla romance or something, which is more than a little disingenuous and whiny.
