I wonder what direction this story will eventually go - does Nat go the route, 'once you go black, you don't go back? Does she become a promiscuous hot wife with multiple lovers with Ethan as a happy but humiliated cuck? Or, does she revert to being Ethan's happy wife - with Ethan dumping Riya after Nat finds out she is pregnant - and the couple move on in their marriage after all their sexual adventures realizing you can't separate sex and love in a marriage. I'm not betting on the last option but it would be a satisfying conclusion.
