I was thinking that maybe they will make the story like an english movie Dairy of a Mad Black Woman, in that the heroines husband is a very bad guy, she leaves her husband, then falls in love with someone else, just when she almost gets divorced, her husband gets paralyzed, she goes back to him and makes him get better, the husband changes to a good guy, but she tells him she is in love with someone else and signs the divorce documents and goes to the man she loves.
Along those lines, Kumud might go back, get Pramad back healthy, he will change for real this time and become a good guy and will think that Kumud is back with him, but bam then she tells him nope sorry, still love Saras and then goes back to him...
I strongly feel this might be a possibility...what do you guys think.
