I'm loving the way in which all the three characters are shown in the show. Firstly:
Madhubala : very strong yet vurnerable (when it comes to love) in the forced dance yesterday DD showed both of them at a time, her mind telling her to go away and her heart is wants to stay near her love. Conflict was really good to watch.
RK : our right kameena was exactly what he has been from the beginning of the show, arrogant, selfcented and egoistic. He left Madhu just to take revenge, and till date he is missing her from the time he left her in Saturdays episode we where shown his realisation of his love, being egoistic he thinks he can get whatever he wants just because he is RK, for him just becz he loves Madhu, he thinks he can get her back, but doesn't realise yet that it is not going to happen that easily, he showed his haq on her yesterday, but didn't realise that he can't get her love back in that way, so soon we can expect his redemption track.
Sultan : as shown earlier is a fighter, he cannot let his 5 year old son to become weak and takes tough way to make his strong enough to face the world all by himself. Yesterday we were shown that he has already developed some soft feeling for Madhu, may be in the upcoming track after knowing Madhu's past he will not allow her to break or being forced anything by RK he will their to support her and fight along side in making RK realise his mistakes.
