i need a story update pls

please can someone kindly expalin is nikila and ipshita evil?

what was the first part of the raaz?

pls tell what is devika all about

So fare Nikky is evil coz she is a selfishness woman who want her son to live at the expense of another person's life. Isphita, we don't know yet.

The raaz is that in Shiv's kundali, whoever marries him will die and he most stay one year with his wife to get off his dosh.

devika is Gauri's nanni and tried of break Shiv-Gauri marriage coz she know about the first raaz.
