First of all I too cannot understand how Sarla is loud and a yo yo and can run here and there and nobody knows. Her smart mother too is so focussed on putting Bua Dadi down that she has given up on Kaushi and Sarla.
I was dizzy the other day when they showed Sarla sitting with Amit, then next second with Rani then next second with Riya and then next second dancing with her husband and then soon in the rick after Shivam.
Very confusing but give it to her for her optimism that her Amitwa will marry Riya no matter what.
