Tu biwi hain, aur hamesha rahegi.
In short Kanha had no intention of leaving Sayuri ever. There goes Saroj's intentions, Anjali's dreams and Sayuri's promise for a toss.
Today's episode had that ridiculous group of people coming to see Kusum. All they do is eat and praise Sayuri's beauty. The guy calls Kanha a lucky man and Kanha glares at him. Of course the fiasco happens with Sayuri describing that beauty lies in character.
They get offended. Kanha waves them a bye. They leave. Kusum shouts and blames Sayuri. Calls her a bad luck.
Saroj tok shouts. Dhanraj rebukes her.
Kusum cries in room, Dhanraj tells her she is crying unnecessarily. The people didn't deserve her etc etc etc.
Sayuri keeps sobbing and Kanha tells her he is glad she was there or else they would have never known about the real mentality of these people. He tells her that he will get a better proposal for his sister. Sayuri mentions about Anjali.
On the other side Anjali is dancing thinking about Kanha. Her graph is slowly mutating and Sayuri is definitely to be blamed in this. Anjali has fixated on the promise Sayuri gave her. This is going to be troublesome.
Kanha tells Sayuri clearly that Anjali was a friend and will be one. She is his wife and will forever be one. He uses the word 'forever' to describe his and Sayuri's marriage. Sayuri gets stunned.
In a way nothing is as permanent for him as this marriage. He has no intention of leaving Sayuri. As I said all these people fail to realize that his devotion to Sayuri has its roots in his love for Chiru. There is no one he loved more than his brother and he is not going to choose Saroj Or Anjali over Chiru.
