SO it seems.. this is the base for Madhu to become heroine..
I think...in this Ballu track...while fighting with Ballu.. RK will get badly hurt...some major injury...may be problem with his spine or he may face partial or full memory loss and to treat him there is no money left with RK or Madhu...Even if Radhaji having some money on her name...that too Bhatia family will snatch from her...so RK will be total Kangal...
So Madhu will try to find out ways to earn money to treat RK and in course she will join films as junior artist and then get chance to act in lead role which will make her super star heroine...
Then in course she will be able to treat RK and get him back in life...marry and they will live happily forever!!!
---------
Other possibility is that if RK gets hurt badly and Madhu not having money to treat him..then Deepali will tell Madhu that she will give money to treat RK but she needs to go out of RKs life and she will get RK only when she repays the money... so that will be the reason for Madhu to become heroine...
During the period Deepali will again influence RK about Madhu leaving him as he is not having money and so on...
We will get to know another hate-love passionate story again...till RK comes to know real reason of Madhu's going away from his life.
Its what I think from past few episodes.
