I think throughout Vansh's revenge journey in acting in front of Saras, he will fall in love with her simplicity and pure heart and just before he realises what he has done it will be too late. As by then, Saras would've found out about his lies and plan and separate. ( I wonder what song or music will be played when their love story starts)
In the meantime, through vansh she will come out of her comfort zone and explore the modern life is and its changes and how women are independent and not just being a doormat.
Then obviously Uma and Kanak will have arguments over Saras pain, and then its another mission for Kanak to sort out.
