Regarding tomorrow:
I think Kumkum will go to jail and while she is in jail Nivi will try to poison Kumkum's mind that she and Sumit are having relationship. And Kumkum might start believing that ab toh usko fasi hogi so why not Nivi and Sumit remain together. So this thing will go on until creative heads get something else in there mind so when this will happen, may be Katara come alive and tell everything or that maid or some miracle and Kumkum will be freed and Nivs's true colours will be known to everyone.
So Creative Heads if you are reading please I am giving you another story of flashback which shows Kumkum Sumit romance and to finish this Nivi Story.
Thanks
Aditi
