C'mon it seems simple for us to say that she should simply accept Shashank but imagine the turmoil of ruining another girls dream(Sumo) specially when you know that person, and also you were introduced to her fiance(shashank) wen they were already a couple.
On top of it her promise to Aziz too makes it difficult!
Personally I cant wait for Prateeksha to courageously confess her feelings to Shashank and put the guy out of his misery, but Damn! the terrible scene when everybody gets to know and all question her character and not Shashank's, is somthing I m definitely not looking forward to.
