I just want to preface that I'm not asking the game to change on that rule. If you don't want to explicitly depict rape on your story then power to you (but with the overwhelming amount of otherwise brutal and
extremely dubious consent nature of so many scenes in the game, it comes across like the strict cut around direct rape is more a matter of optics/censorship than any kind of moral stance by the developers, even if the intention was genuine).
The issue is only that if you're gonna make an adult game with a heavy focus on sexual content and strongly imoral themes, omitting/censoring rape as a story-element leaves a narrative gap. It is not an unworkable problem and you can absolutely craft a great story while skirting around it, but it takes careful work to make it so the absence of rape or other forms of non-concensual content doesn't stick out.
I'm sure eventually you can write some piece of backstory content that will explain why Andras might be secretly against rape even if he threatens it (something something his mom was raped by his father and he witnessed it and was traumatized by it/he believes a "real" man wins by getting a woman without resorting to rape) or whatever other explanation for why he is a massive bastard except in this one thing. But until then it will just feel a bit out of place with the rest of the game's universe.
Also Rein weren't you the one bragging a couple pages back about how you were the one who came up with the Delane content at the end of Werden's route? About how there "had to be consequences" for the player disobeying the twins and trying to be good? Feels a bit funny for you to go from that to "oh Alexia honey, all you have to do is just say 'no' to unwanted sexual advances, nothing bad will happen from that

"
