I guess RK feels MB is keeping the fast due to tradions and not coz she thinks him as his husband it was always RK who said Madhu meri Biwi hai I consider her as my wife but MB never voiced her feelings maybe that's teh reason why he is trying to distance himself from his biwi by sleeping on the couch as wellJhooth muth ka pati is simple bcoz he feels mb does not consider this marriage complete she is doing thsi for d sake of tradition and not out of lovethe promo clearly tells that madhu is going to starve till death and acc to the sbs videos mb was saying i have trust on our relationship u will comeSo mb will faint and most probably land in rk's arms rk will realize that this is not mere tradition but mb has loyally kept the fast and he will break her fast 😃 thus both of them will winlove-Piya
