In the last episode of Madhubala On Colors, RK ( Vivian Dsena ) has told Madhubala ( Drsahti Dhami ) that he will not come tonight.
It is the night of Karva Chauth when Madhubala wants to break her after looking at him . Madhubala has challenged Deepali as well that she will get her fast completed from RK hand only.
In the last few episodes , Madhubala clearly showed her for RK is also shown with a soft corner for Madhubala always taking care of her.
Even now he has angry because Madhubala is not well and not taking even water due to the fast.
Although RK does not believe in Karva Chauth but his care for Madhubala makes us assume that he will come to her for sure.
