My mom watches Deiva Thirumahal, and she told me that they have shown another actress overtaking her role now, so she's not doing it anymore. It's quit sad considering Naagin for being a finite show and she has been doing the role for over 2 years.
she quit deivam thanda veedu serial in tamil before one month my mom also watched it in that serial sudha mam plays a important role character get weak due to crap story line so she close the agreement
