Hello dear!
firstly, let me welcome you to the forum! 🤗
Ok, now, Anupama is hated by her father because, when she was born, her mother died while giving birth. So Vikram thinks that it is because of her that the mother died. He blames it on her, and calls her manhoos.
Now, after the wife died, he married this lady Maya who was able to convince him that she takes good care of Anupama but the reality is that she treats her like scum. She is doing this because Anupama is not her real daughter and she wants that Anupama and her dad will never have a relationship (very evil). Maya's mom is also that way too. They both want only the good things happening to Maya's children. And they always try to prove to the world that Anupama is really manhoos. And Vikram does not know what is going on behind his back, but he hates his own daughter...
Hope that helps!
