At the risk of being labelled as a negative person, I’d still go ahead and say that can’t be the only reason. Even in Rishta, the lead couple is separated but do you see that having an impact on their performance in RWSP.What I observed is that rwsp follows the current plot. Ofcourse they can’t give any clue from the ongoing plots. Now sairat are separated. Virat is longing for her. That’s why that song. They will place virat pakhi close because the story shows the same!!
there is nothing to fret! This is the current status of the families of starplus. So they will show only that. Anything else will reveal the plot.
Imlie’s Arylie ship has stopped existing as of last week, so ideally they shouldn’t even be there forget giving couple performances! While I do believe that the show’s plot may play with character interaction on RWSP but that couldn’t the sole reason of Ghum audience not getting leads performance.
