I think Vidhi isn’t just naive, but mentally not quite there. I don’t know the correct medical term for it, but she isn’t just your regular, clumsy, naive FL, but has a legit psychological issue that makes her do child-like mistakes and get flustered more than usual.
I hope the writers would call it what it is, instead of terming it naadani and innocence. That would explain the OTT behaviour that she has displayed from the beginning and the earnestness with which she tries to follow orders to the T.
It may also be why her father is protective about her and gets worried about her marriage.
