Also Varsha's teachings. Ki she needs to tie her husband to her, she needs to secure her place in her sasural.
She was worried about this even before Mishti ka rishta got pakka. Mish had to constantly reassure her that everyone loves Kuhu in RJV house.
Even Kunal still thinks that surrogacy is right and supports Kuhu of being a surrogate.
Kuhu and Kunal are foolish enough to trust Meenu.
Kunal wants Meenu to accept him as beta. While Kuhu wants future should not be ignored. Where both are getting fooled as well as making everyone fools in the process.
Hopefully, they learn that Meenu cant be trusted at the end of this track.
