Radhas role in the serial

I have been wondering for days how Radhas entry and role could possibly contribute to the serial. The only thing I can come up with is that after finding out how Samrat tricked her, he might be sentenced for rape.

idk why she's in the show for?

Radha is weird, who knows what role she's playing. You would think she got the last man on earth by her on cloud 9 behaviour. Maybe Radha will be the vindictive, psycho chick in Samrat's life who will make his life miserable, after finding out that she was Samrat's washcloth, who he used at leisure and then discard.

I kind off thought it was like to show how like in real life, once a woman escapes her abusive husband, he ends up finding a new prey somehow anyway. Idk, could be wrong though.
