For those Who are saying, married woman pe nazar dalna dekh ke log bhag gaye, let me remind them, Anurag has made it pretty clear that he wants Prerna back with full dignity and when she realizes she still loves him, and not at the cost of her badnaami.
Waise married women pe nazara dalna galat hai but pregnant woman ko blackmail karna chalta hai. Kyunki he accepts he is no saint.
