Afterall, who knows its creation more than the Creator. Rajan Shahi is the Creator of the Bidaai World. The inhabitants of the world of Bidaai are servants of Rajan Shahi's will. The CT can be described as the Angels (Farishta) who carry out the wishes of the Superior Power (Mr. Rajan).
For us this is entertainment (or atleast its supposed to be)....for the CT and RS ... its more... much more.
Sadhna is doing her role. This has been the main characteristic of this particular person. Her role is supposed to go through such period repeatedly.
Infact, Ragini is a character who is nice, ceteris paribus. She cannot be nice without that factor.
Ragini is shown to be a girl who would like to stay out of issues. She is concerned and defensive about her own life and wishes. Perhaps because its her dream-come-true. She is so much lost in her world, and her possessions, that she cannot see anyone - even when her own zameer (conscience) threatens/scholds her, her mother is ill but she forgot to mention that to Ranvir or anyone ... her father has a broken hand, she still doesnt interract with him.
Sadhna is someone who has faced horrific pressures and confinements since her childhood. Her dreams were made secondary by the sheer importance of her duties. Because she was living with her Mama-Mami, not her parents. This makes a GREAT difference (not to mention the Mami).
Its easy to go ahead and blame it all on the CT or RS. Mr. Rajan points it clearly and simply 'Are beautiful people more happy than ugly bettys?'. If we consider this as a title of an essay, than the Bidaai story fits in harmoniously.
Lets look at Bidaai in a more cool and careful manner. And not loose our identities, trying to attach ourselves with a character which we may appreciate alot, but are not.
