Who is Juhi?

can anyone please tell me who is Juhi? is she Rahul's sister? and why would she wants to hurt Rishab?

juhi is rohan's daughter and rohan is rishav's elder brother who had to leave home because rishav played some trick with them. juhi knows that.

Juhi is Rohan's daughter. Rohan is Rahul's and Rishab's elder brother, and because of Rishab he and his wife had to leave the house. Juhi blames Rishab that she did not get the love of her parents.

thats right rohan is back to take refenge on Rishab

Then why didn't Juhi leave with her parents?
