Every production house starts a serial with a basic story and the improvises with mini plots and variations and in some cases big variations depending on how the audiences react to the story.
For example, given that Naveen was in the first episode it is clear that the Naveen track was always meant to be. However his reappearance was added because the audience really like him.
I am trying to figure out which bits of the current mess that we are in are part of the original story and which bits were just you made to satify Hina's dates or TRP or something else.
You clearly made Shivani pregnant, because it was not your intention to make Prerna pregnant. And then why did you change you mind about her and Ronit and completely ignored them. What happened?
Why did you bring Mishka in? Your original idea was to have some unknown girlfriend for Anurag in his past called Sagarika (I think) and then you brought in her - We thought there was a purpose, but no...it turns out there wasn't. What happened?
You clearly planned to kill Moloy. You even released a promo with Nivi and Anurag crying. You then killed Rajesh and set in motion and ill thought set of events. What happened?
Did you always plan to get Anurag married to Komolika? I think you probably did. But if you changed direction so many times, why didn't you think time? Why didn't you leave it as him having done the saat feras with her and walking away. Why did you make Anurag this person we all now do not like? What happened?
