So, I was thinking today...could Ekta be planning the story to go like the movie: Dhadkan.
By introducing this new girl in Yug's life...we all know that she will fall for Yug, who will hold out hope for Vrinda. This is the same thing that happened in the movie Dhadkan where Sunil Shetty became friends with Mahima Chaudhry who was madly in love with him but Sunil was holding out hope to be reunited with his love Shilpa Shetty (our Vrinda) who had been forced to marry Akshay Kumar (RB in this show).
So, basically, Shilpa comes to Sunil and tells him that she has fallen in love with Akshay....it was so heart-breaking because he sings the sad song: TUM DIL KI DHADKAN MEIN (http://www.youtube.com/watch?v=I2VGlyEOQbo&feature=rec-HM-rn)....waiting for her (which btw, I can totally picture Yug singingðŸ˜), only to have her come and break his heart.
In the end, Sunil finds out that Mahima loves him and then marries her.
This could happen....only way that introducing the new girl would make sense. Sad, but so true.
