Why does Niyati have to be so goody-goody?? Instead of thinking and coming up with a more smarter solution, she decides to take the blame. For her evil no good Buasa. If she wanted to help her Buasa anyway, why did she go to Amit and ask him to understand??? She knew how he was like to Buasa, does she expect special treatment?? She does things without even thinking about the consequences. She needs to use her brains more.
If she did it so the family wouldn't get bad publicity, then they will get bad publicity anyways bcuz she is the kulvaddhu to-be of the house and it was in the news and everything.
