it's always that. Anurag and prerna relationship is betrayal, lack of trust, misunderstanding, deceit, lies, disloyalty. If the theme is indeed betrayal and ekta said the darker side of love is being explored sacrifice doesn't fall in tune of that nor does it excuse anurag from what he did.
Betrayal just seems like a click bait to me. They won’t want to ruin their dear ML. Round and round we go with sacrifice mode
