I have been watching KZK only from Prem's entry, I am not sure about the past characters but I am assuming that Bajaj's first wife Menaka is still alive. In that case, one possible twist may be the entry of Menaka....which might force Prerna to leave Bajaj n his family.
Menaka's entry might be possible if ekta hasnt shown her death clearly to the viewers. What do u say guys?
