As much as I liked the Ro-K pair, I am glad that Kasturi took this decision because Robbie fell in love but never tried to understand it or its responsibilities and limitations. I am a huge fan of the original Sujal-Kashish pair and hated her for choosing Piyush. But I believe that Kasturi is justified. While in KTH both Sujal and Kashish entered into a misunderstanding due to their respective siblings, and realistically chose to believe their siblings whom they had known their whole life over the unknown prospective in-law whom they had not much info about, in Kasturi how easily Robbie allowed himself to be manipulated was hardly worth applauding. And even if the pregnancy report was true, what right did he have to question her past when his own past was so colorful. If he had loved her then he should have thought about their present, their future and not get hung up on a probable past.
And I have slowly started liking Raunak better than I ever warmed upto Piyush. His offer of withdrawing back seems a lot genuine than Piyush's half hearted and guilt-inducing attempt. After all Raunak was never in love with her, and wasn't even a very close friend but when he saw her plight he stepped up. Kasturi was very right in pointing out that his suppport got her through the worst phase of her life. She was termed as a *****, her parents were on the brink of suicide and she was to be married off to a man twice her age. Raunak could have chosen to stand by and watch, he had no obligation to do something but still he made the effort. I am hoping that the Raunak-Kasturi pair survives because they both have a backbone and right attitude towards relationships.
