No judgment, just sharing opinion here.
I'm the opposite, for me the cheating and going behind the back it the thrill that excite me.
Which is why i said i wished for the option

. Because i like the cheating aswell, just my real preference is for ethical non monogamy, be it romantic or just sexual. Now i know that for it to be added there would either have to be a quick scene where they talk about it and agree to it. Which can feel a bit hollow and maybe pandering. Or it needs several scenes to make a buildup for it, which could be hot as hell if made correctly, please note that i'm not interested in making Conner a cuck, more of a Stag (same thing, but remove the humiliation and femdom aspect of it, just getting turned on by the partner sleeping with other people, see the MC in Deliverance for example).
But that's both possibly not part of the vision the creator has for their game, and it's more work on the creators table. So don't see it as me being belligerent and trying to demand something, just like you voicing an opinion, and a wish ^^.
