I watched this film too, it was good. Especially the actress, you can say I got a crush on her while watching. In the beginning, I couldn't imagine Sita Mahalakhsmi's real identity to be something like that too.  And about Afreen 's identity, it was also a great twist too, I nearly got a shock and became emotional, how fate turned out to be like that. 

Well, I am not a good movie reviewer still I would like to suggest you to keep the story short, not to reveal everything, you just described the whole story, hahaha. Thankfully I have already watched the film so they didn't affect me, but you have given spoilers after spoilers without any alert or anything. Someone who hasn't watched the film won't enjoy anything as he/she would know the real story or what's going to happen next through your writing, won't they? so there will be no fun left.

Try to give spoiler alerts. I would have loved to hear more of your opinion and reactions over the different scenes and story turns.
