The conversation between Saxesna and his son, Adarsh tells it all. They want Komal to bring back because it might create problem for their daughter. Not because, they want their Daughter In Law to be back. Thats not a good thing for a family which taunts others for being insensitive. At one point they say they have accepted this relationship but in reality they still treat it as an unwanted marriage.
Ok, Komal is an extremely bad girl. She has no manners. Agreed. But, did Adarsh ever looked at her as his wife? Has he tried everything from his side before concluding she is bad?
I would say, since he went out married her just to safegaurd his sister's life, he is ignoring the Komal . It was him who approached Thakurs for asking that girl's hand. Doesn't he has any responsibility?
Mr. Saxsena nor Ms.Pratigya even for a moment want to see why Krishna is being so protective of his wife and her family. They are also as ignorant as Thakurs in distinguishing black and white. Thankurs doesn't want to behave good with Saxsena family due to their ego so as Saxsena family doesn't want to behave good because they are so much into negativity.
