Few theories in this twitter thread making some sense .Below theory is one among those:
MJ was pretending to be kind wth Maya but actually he was threatening her by killing her father/brother as he was trying to separate M&R. So she was forced to act as she was cheating R wth his father just to make him hates her.
Some of Maya's lovely Memories belong to Rudra..But other memories either they belong to MJ whn he was threating her OR they belong to Rudra after he was persuaded that M was cheating him. Especially when he asked her to determine her price.
Why 10 years and why Rudra doesn't remember her? I think both of them had an accident and Rudra lost part of his memory including the face&name of M. While Maya stayed in a hospital for 10 years.
This dialogue when she said, "I've come here because of you Rudra. Because the past and the present must be connected".
Except for the part where Maya stayed in hospital for 10 yrs.. Remaining theory makes some sense
