Neil a successfull young man in love with his best friend.
Samaira a well educated girl struggling with personal problems.
Radhika a young woman determined to make her own identity.
Arjun a man with nefarious motives, manipulative and calculating.
At the moment this Nandini revelation came, my sixth sense told me that perhaps she will enter in future as the main negative character. I had hoped a lot that it won't be so or else it will be very predictable. A handsome young man taking revenge and only for it to come out that someone else was pulling the strings behind the screen assuaging him of any guilt.
And that's the route cv's took.
At least one thing is sure Arjun will slowly but surely turn positive but not completely cuz Nandini will emotionally keep him tethered to her.
I have a feeling that Arjun being manipulated from such a young age doesn't realize Nandini's actual character.
Radhika will reveal it to him far into the future.
Only after that he can change.
