Prem ko yahaa maarke, fir if he wakes up somewhere else minus memory.. and Sanjana meets him.. that would be another track.. and then later obviously he'll meet Heer..
I'm saying this also coz I read in an article about Dimple J (Sanjana) taking up some new Balaji serial. They mentioned that she's on a high as along with this new role, she also recently bagged a parallel lead role in KDMHMD. It would be called a parallel lead only if she's more role, right?
