After reading the whole post I have to agree with you. And also thinking yes it has been already 7 months to the show, still female lead is where she is before in terms of her characterization, I have to agree with U.
I am still hoping soon it will hapen, soon CV's are going to work on her character. I am sure the actress too must be waiting and in every interview of hers she said she is going with the flow and waiting for her heroine track to start. So like her we fans are also waiting for that day.
But I guess it's been a long time now with 7 months passed, it is really time for them to work on her character. I am just hoping with Ballu's entry CV's might concentrate more on Madhu's character. So waiting and hoping for that to happen in the following weeks.
