AANCHAL DWIVEDI a.k.a KAVERI is undoubtedly a VAMP on the screen, but in reality she is known to be a very soft spoken and kind hearted girl. She does not pick up quarrels with any body and plans to settle down with a boy of his parents' choice in 5 years from now. Regarding the role she is essaying she says " I can't believe spitting so much venom on screen. This is definitely not me."
So Aanchal as long as your Onscreen Self is poles apart from your Real Self , there is nothing to worry.
