First of all sorry for my poor English...
Hmmmm it's Just a thought...
I think the drama will be just like Veer-Zaara.
Karan will fall in love with Arohi and he wants 2 marry her. Karan wants Arjun out of Arohi's live.
Somehow Karan will play the nagative roll (Manoj Bhajpai in Veer-Zaara)
U know na what happends in Veer-Zaara...
Hmmm Arohi's Om-Locket (Taweez of Sharukh in Veer-Zaara) hmmmmmmm
Karan will make a deal with Arjun. KARAN WILL SEND ARJUN IN TO JAIL!!!
But what kind of deal...
Well Ekta Knows ;-)
I can be wrong, but it's just a thought :D
Thanks do replay.
