malhan's hidden sister

What if Abhishek, Nishchay, and Prerna Malhan had a sister,

A small mistake at the hospital changed everything, and her existence was erased before it could begin.

Seventeen years later, she is living a simple life in Mumbai with a middle-class family, believing they are her real parents.

She doesn't know she was adopted.
They don't know their sister is alive.

While she grew up loved and protected, the Malhans lived with the pain of losing a daughter they never got to meet.

When the truth finally comes out, will she accept the family that lost her before they could love her, or will she choose the parents who raised her?
