Is Pihu a all positive character?

Hi Friends,

Its my very first post in this forum as I am not a regular viewer of the show. i know its nice but I watch only one or two shows at a time (Balika Vadhu and Diya Aur Bati Hum)

I caught glimpse of few episodes before this leep when Priya got to know about Pihu's lie (She framed some guy for Rape or something like taht) And then I followed one or two updates wherein I gotta know taht Priya and Pihu met an accident in which Pihu slipped out and Priya collapsed. an dended up in coma ...I didn't watch teh episode So I was confused ?
And after that day I followed an update wherein found Pihu is head over heels to marry Ram with some Juhi!


I felt irked...and then I thought probably Pihu was behind that accident...I doubt! I know she is the lead now...she cant be that negative but as i haven't watched i feel suspicious. I think both Juhi and Pihu are negative! Am I wrong or AM wrong! :) If so cud you brief me about the happenings...Like, was everything shown about that accident! Why Pihu is so frustrated about Juhi Ram wedding! Is it coz she can't see Priya in coam and Ram living Alone or something else!

That guy Pihu framed, was son of Priya's vicious ex- lover and he might have told some false story to Pihu also and probably she started hating Priya!
