Adultery Tale of a lustful revenge

[THE EVIL]

I have completely agree with your view.What I thought Raghu will seduce nusarat and she will become crazy for sex with Raghu following kinky update.
But what happened suddenly she got married,Raghu returned and had an affair with old lady something doesn't match up.
May be you have delayed marriage part and continued with Raghu nusart part before marriage would had much fun.After marriage she is not sexually happy with Kabir remembers her affair with Raghu and suddenly he appears then they started sexual affair behind Kabir's back would had fun,that's my point of view.

Sudha isn't part of the plot, her charchter is a mere trap for nusrat to get seduced (totally unintentional) by raghu once again. Infact there are no more scenes of her & raghu. Everyone seems to have speculated this whole scenario horribly wrong.
