Kasturi - Mausi is the bad one

It is real fun how things keep on happening in Indian TV serials (and how they keep on copying each other). So, from a time when Kasturi was in the bad books of Robbie because she had blamed him for Raunaq's death and vowed to take revenge (and as a part of the anger that Robbie felt, he had got engaged to Anita (who was actually plotting against Robbie and was in cahoots with Raunak)) (did you not see something similar to this happening in 'Kahin to Hoga'), to the point where she learns that Raunak was alive, and this was all a plan by Raunak to get hold of Robbie's wealth.
Well, soon things start to change away from Raunak's and Anita's favor; inspite of the best efforts of these 2 (and Mausi supporting them), Robbie soon starts to get the old feelings for Kasturi again. He breaks off his engagement with Anita, and moves closer to Kasturi (but Raunak has re-emerged on the screen in terms of trying to break the things between Robbie and Kasturi).
Raunak is torturing Kasturi a lot while pretending to be ill and bed-ridden to others, and Robbie can only watch when this is happening. Eventually, Raunak and Anita decide that they have to get rid of Kasturi, and they decide to try and kill her (Raunak has already made a number of people believe that she is mad). However, Robbie also reaches there, and it is believed that Robbie was guilty of shooting her. The police get involved, Kasturi's parents are also very angry and tell a lot of things to Robbie's parents.
And then they find Kasturi, she is in a ashram and has reverted back to a child like mental state (remember Saat Phere, anyone ?). Soon, Raunak decides that she has to go, but this time he is caught along with Anita. Mausi also abandons them, and Raunak is really angry at this, but is unable to do anything. Mausi is still planning, scheming, how to get Devika's and Robbie's wealth. And so the serial moves on, with newer villains (and maybe some element of black magic getting added).
