Don't you see that whole blame of EMA is going on Kunal only, showing Nandini had no part in it?
Nandini not fighting Rajdeep and getting ready to die because she didn't wanna break her promise to Mauli?
Audience's reaction will be against Nandini because when a woman is shown to respect her friend so much that she'd die before she breaks a promise made to her is a woman is great strength, but the same woman slept with her friend's husband, how ridiculous is that?
