Paridhi may be a little crazy and childish, but, she is not foolish. But then again, she is not stupid to sign a wrong signature. And I don't know what happens in India to people who write wrong signatures. I am sure it's not good.
Anyways, I am sure that Paridhi did what she did to get Radhas guard down and once that happens, Paridhi will make her move. 😊
