the only things that u cant prevent and maybe u can arguably say that is NTR as far i know is samson with beth, and grug with Ziva because there is a 3some scene grug and MC with ziva, also u can arguably say that as long as grug is alive he probably is fuking Ziva from time to time since they are living in his house after all, and if she had sex with him in front of u why not when ur not there, but like its very tricky tinking like that because after all u never get to see that.
Imo the game is really good how it is rigth now, maybe they can do a poll to see if there is a big group of patrons who actually want grug dead and give the option to kill him, i am no patron but actually i dont mind him alive, the poor dude recive a beat from u, from the orcs and then his house is used as a church, and all what he was doing was living his life without causing any harm
