Varsha has always been one of the best characters of YRKKH. In fact the only reason I watched that show was for varsha and shaurya, they had a really sweet love story going. Anyone who has watched the initial period of the show would have noticed that.
Now coming to mishti’s sudden character change, this is just my understanding as to why she is okay with KuKu. Somewhere subconsciously I feel she wants to be accepted by kuhu as her sister. This girl has always pointed out that she is the outsider and made her feel the same. Maybe she feels helping kuhu with her love might, if not erase, at least reduce the bitterness between them and truly be accepted by her. It could also be mishti’s way of making up for sharing everything which kuhu believes only she is entitled to and has been snatched by mishti.
As for the kuku relationship, the reasons for mishti-kunal breakup have been all personally about mishti’s individuality. Firstly the job which kuhu has no idea of doing. She is the kind who would be happy with a husband who provides for her. Here, they have a common opinion.
The next reason was the surgery - if kuhu had glasses and kunal gave her the option of surgery, she would have jumped at it. Both kuhu and kunal give importance to their appearance. So yet again their opinions match.
Lastly mishti’s father, mishti has a dark past, which was the final nail in the coffin for the major showdown between mishti and kunal. As of now in the story, kuhu doesn’t have any baggage with her. So, technically their match would be perfect socially too. Two people from a stable rich family getting married.
According to mishti, kuhu is just a spoiled girl with the usual marriage dreams of every girl. Also the constant guilt trip of dumping kunal (the perfect match according to kuhu) could also have played a part in this.
As of now, I would like to justify mishti for these reasons, but I would like to wait and see what happens when kunal knows about kuhu’s parentage and how he reacts, also I’d like to see if mishti still feels kuku are made for each other. In our society, orphans would be accepted easily, but kids from extramarital affairs are treated worse. So I will wait for that drama to unfold and see what happens.
