Ranveer's dialogues were well written, and I particularly enjoyed the moment in which Mamta looks back at her husband and realises the reality behind Ranveer's comments, which she had previously been ignorant of.
In terms of other television programmes, I've seen characters speak out against infidelity, particularly a number of female (main and supporting) characters, who spoke about it more strongly than Ranveer, but the situations in which these characters spoke vary in different ways, so I won't compare apples to oranges and undermine any character’s stance.
