Nandini: Pyaar karna koi besharmi nahi

BUT

lusting after the HUSBAND of your bestfriend (who basically gave you a new life), sleeping with him, having not an ounce of regret even after that is besharmi ki hadd.

What did the writers have in mind when they wrote Nandini's character? I can't feel even 0.1% of sympathy for her despite her past. She's the vamp of this show! A true narcissist who only cares about herself and doesn't give a flying f about how her actions affect others.
