It's interesting.
Madhu seems to be a simple girl trapped into modern girl.waiting for the story to unfold. How RK is involved in Padmini's death.
I wouldn't put Madhu in either of the categories. Like most girls now, she's modern but still respects traditional values. :)
How Padmini's death is connected to Kundra, I shan't reveal now. :D
Thanks for reading!
