This is my personal opinion, and I understand there are many Arnal fans here. 😛 Its Murnal as Bulbul who had that spark, natural flair, liveliness and wonderful on screen vibes with other characters both from Arora and Mehra families and she also carried off that modern, beautiful, daring, yet chirpy girl's look and behavior that convinced why many men on the show fell for her..
In initial months of KKB Arjit as Purab clearly lacked in diction, acting, screen presence and looks compared to other able cast of the show. Did not feel any real spark of Arjit with Shikha or Mrunal even with Shabir at that time. 😳 After several months when he improved in performance and also sported a more matured built up look, Arjit fitted the ball as Purab the lover boy with most wanted Bulbul onscreen and also as dost and bhai of Abhi & Pragya. 😊
Coming to Vin & Ruchi as Purab & Disha they seem to be fine actors when given individual scenes, they both also did well as Rajasthani couple when they duped Taaliya and Raj in disguise to help Pragya steal property papers couple of months back. But Ruchi looks childish, short, dull and chubby when compared to tall, suave and slim Vin, that's one drawback on screen. Other being their individual characters of Purab & Disha don't have even one common interest explored on screen as friends till now, except both being helpful and good natured. 😳And they both hardly get any meaningful scenes other than fillers these days to develop that couple wala bond, right after property papers issue these two actually became guest actors of KKB..
