Right. I agree. In reality, I don't think any of us care about off screen dynamics. We are all here watching a show. To put it roughly, hame Paisa vasool entertainment chahiye. Rest is vicarious gossip.
Only if their reality affects the show will it become a problem. And it does look like the show is getting affected.
It is the channel & the PH's responsibility to sort things out. Theirs is not the first show where leads have a problem. But the concerned PH always solves the issue.
Noone would leave a show because of not getting along. Nor would they be asked to leave. They don't have that luxury especially with shows flopping left, right & centre.
Oh well, we can't do anything. There's a logical course of action to follow, if they don't do it, it is their cross to bear.
