I wish they didn't do this to Kuhu. She was really a good character that had shown so much growth since the leap. But I am also so confused by her. She knew from the beginning that Mishti didn't love Nishant and to protect her Nanchak she was constantly trying to break the wedding coz she knew that Nanchak would never be happy in a one sided marriage just like she is suffering he too would suffer.
Maybe this is a way of Kuhu trying again to separate Mishti and Abir and then realising how wrong she was and finally getting over her hatred for Mishti and truely accepting her. Also it would be a way to redeem Meenu if she fights for Abir and Mishti's union. I just wish they didnt sacrifice Kuhu like this
