Wouldn't you want to do the same for your sister?
So yea, she could have thought of another way but what other way did she have?
Maybe she could have stopped the marriage half way but do you think the truth would have still come out?
Of course not
Because Mansi was unsuccessful, she was angry! And her anger caused her to speak the truth.
I think Purva is not to be blamed but it is all Kamini's fault! If it weren't for her smart idea of bringing a new bahu, this day would have not occurred
And now look how she is treating Purva
Yikes!
Well what would you do if you were in Purva's place?
