And still Kunal bht acche hn?

If Rajdeep was horrible as a husband, Kunal too is a horrible husband because of other reasons.

Just because reasons are different, doesn't mean Kunal is better husband.

Mind you, Kunal might be a better man but definitely not a better husband. So, Nandini saying Kunal bht acche hn, means she doesn't go by general but only by herself. If someone treats her good, he is good; otherwise bad.

That's the gray of this character. She is not like someone who wronged my family or my friends will be horrible to me too.
