When you think about it, Savita and Sulochana are alike. Sulochana too was greedy. She was so obsessed with wanting Archu to marry a wealthy, educated guy that she refused to see the good in Manav. All Sulochana could see was how poor he was, she insulted him and made a huge scene at the wedding hall. It took a while for Sulochana's greed and stubborness to stop, hopefull Savita too will get a wake up call.
Manav and Archu are too quiet, too kind hearted. They are two people who love and respect their elders and would never want to hurt them, but at the same time they are suffering because of their mothers. Their quiet nature is what makes people take advantage of them.
