I want all of you to think positively. If Mr. and Mrs. Mittal continue with the show, it'll make Yash and Aarti's story more popular. Those who tune into the new story will have respect for Yash and Aarti for building the premise of the show. Please be open-minded! I'm sure this wasn't an easy decision for the PH! They could have chosen to end the show, but they didn't, which says that they're attached to it. A lot of people have been worrying that the essence of Punar Vivah has been lost, so many people were complaining, and instead of dragging the storyline, they decided to give it a good ending. As for why Gurmeet and Kratika cannot play the new roles -- maybe they don't want to play the new character's, maybe they want to move on. Maybe GC wants to finally try for Bollywood, and KS wants to sign something else? They've grown so much as actors through this show, perhaps they want to grow more with different roles now. We shouldn't blame Mr. and Mrs. Mittal for this too.
Just remember, the new Punar Vivah will make Yash and Aarti's Punar Vivah story all the more popular and respectable! Plus the Mittal's have been fabulous with their storytelling so far, so I'm confident that this new story will work out, but we'll see what happens.
I wish them the best of luck from the bottom of my heart.
