Bigg Boss ex-contestant and serial actress Reshma played the role of Vandana in the serial. However, she exited and a newcomer actress Vinodini replaced Reshma.
There's no official confirmation as to why Reshma was opted out of the serial. Notably, Reshma was recently cast as Radhika in another famous serial 'Baakiyalakshmi' on Vijay TV, replacing actress Jennifer.
