That whole Champa in love with DV was a very poor decision on the part on the writers and just another way to make Sugni appear Mahaan.
In real life, no woman who was raped will fall in love with the man and want to marry him.
She would be behaving the way Champa was initially when she was raped. My personal view is that the CVs realised that Champa was getting alot of support from the viewers and decided to show this complete change in her to make us dislike her. After all no one must be better than Sugni.
If that is what they wanted to show, then they should not have have DV raping Champa but her agreeing to sardakai because she was in love with him.
Despite this turn in Champa, I still sympathise with her because after Sugni tried to use her, she never tried to help her at all. Sugni is only caught up in herself and torturing TVS nothing else.
