I dunno, I thought it was phighly relevant to the topic - discussing whether romance is in the game and what people's expectations of it are. That the meaning of the very title of the game is being claimed to be related to this is pretty significant.
I agree....
"Original Sin" and a couple of humans that certainly look like a couple walking hand in hand on the game's box and every commercial sure checks the cultural checkbox.
Also note the background of the game's main art(also box art, the one poster seen everywhere) looks like a battlefield...looks like chaos and pain and pain and suffering there in their wake.
