That woman never loved Vivaan first she got obsessed with Suraj, than Vivaan and now power. She is a sick and selfish woman who only loves herself.
Really Suraj saved himself from this disgusting woman by doing the bride swap. He got the best and most loving wife ever who will always stay true, loyal and go to whatever extent needed for him.
To be honest I don't care if Imli-RV are pretending to be married or actually are married. All I care about is my Sukor and excited to watch this new phase of their love story.
