Maya never knew mamsahab

If maya was mausi
How did she not
Know who is mamsahab
And how come she never knew that
There are Tara and arohi look like she
Never knew arohi had a look like how cime

I had the same thought.

I guess Deep kept Tara hidden from his family and no one knew about her except Prithvi. Or maybe Mausi didn't live with Deep until two years ago when Deep needed her to act like his mother. Or as Tweeg said, maybe it's her new role?
