I'm on the same boat as well, ZWG made me curious. Although I'll most likely not read based on some of the comments post that I have seen.
If you don't mind being semi spoiled about their relationship development I recommend to read this -> https://www.mangago.me/home/mangatopic/20085539/
So yes the story is absolutely good, one of my favorites, I was thrilled to see Rix and Nuah show up in Zerowakes especially in the story! So I can say that it is always consensual with the two of them. But in the story zrix is cursed to be out of his mind sometimes so others attempt to sa him a few times, if that is something you're ok with its great story.
OK so im trying to recall, that chapter was the incubus, there was one other time the two get captured and almost sa happens and another when the curse makes him lose his mind and some random dude attempts sa until Nuah stops it like the other times, im pretty sure that is it, and yes it was because Banam is a full divine being and not because Rix found him attractive

I've been a BL Yaoi reader for 12 years, but I never tried reading this. I play ZeroWakes Gates and Rix Vanus is one of my strongest Espers (SSR) so I looked him up and saw this now. Is the story good tho?
