well no as you say there is more going on. For me it is just that... and lust and insecurity but that is totally her.
I did not mean romance of any shape or style. Boss is not a simple monster. In my opinion. I wait for SC to show us what he really is.
For me Wife's behavior is not explained otherwise.
A parallel with white fantasy would be that Boss is the evil witch who brings the princess a beautiful apple and tells her, eat of it my dear. She does and immediately goes to sleep. Returning to the dark fantasy, what would it take for Wife to wake up? Can she even wake up? I would say another brutal betrayal should do it. Send her to be raped.
Or maybe Boss knows better than to do that again. No telling where this will go from here. My hunch is that it will be dark.
