Who is Anjali?

Who really is Anjali? is she sumer and gajri's daughter or vikas and sunerhri's daughter? who is she and how is she shamsher and arjun's sister?

I'm so confused can anyone please clarify?

supposedly she is Arj/Sham's sister. But don't ask me how it is even possible! No logic 😆😆

I have not watched before entry of new aaradhya , no idea exactly if she is real / adopted / cousin.

Probably will be paired to aradhya bro who is yet to be enter.
Hope anjali n aradhya bro turn big catalyst for bonding of aradhya n shamsher.

I just now urfi did play anjali before seen some pics.
