Prerna's character, the main protagonist, being played by Sheweta Tiwari in Balaji Telefilms' KASAUTII ZINDAGII KAY is likely to end before the end of December. This is being seen by the Ekta Kapoor the only way to save the TRPs from falling, which she thinks might be possible after the aggressive promotion by Sony of its newly launched soap KULVADDHU, in the same time slot as 'Kasautii…'. Earlier, too at the time of launching of Bigg Boss on Sony, Ekta had successfully used this publicity gimmick to save GHAR GAHR KI KAHANI, by giving a make over to the Parvati's character.
