Rajrani
Rajrani is a desperate mother who is consumed by the sufferings of her son who is jilted in love. She tries to ease his pain by resorting to drastic measures without any thought for other's feelings including that of her own son.
For her, Gauri is just a pawn in her plan and she is 'sweet' and 'nice' to the girl in the beginning. But when her plan fails, Rajrani wants to get rid of Gauri and is furious when Gauri re-enters her house as the bahu.
Rajrani now begins to hate the girl and her family intensely. As a mother, she had never shown interest in bringing up her children. That's the reason why her children were never brought up like normal children.
For her, love and marriage are materialistic propositions. She is always maintaining relationships so that they can help her husband's business flourish. She is a control freak and is the strong matriarch running the household.
