The show has always been about ViTharv. Phase one was them falling in love and separating. Phase 2 was Vividha trying to bring Atharv back to normal. Phase 3 was them separated again and Atharv's memory loss but finding their way back to each other. And now phase 4 is them married and now coming up against KK.
Ravish was part of their journey and the drama in the show. He came when KK left. Now his character is not required as KK is coming back.
As for the TRP's, if SP were really bothered about the low TRP's, they would never have extended the show. Maybe it might end in a couple of months, but at least we will get to see a proper conclusion with ViTharv and KK.
I don't know why one set of fans keep harping on about the TRP's cos no one cares except them. And what should it matter to them now anyway as their favourite is leaving.
Have some dignity and leave the show and forum gracefully and look forward to your favourite's new show.
