When late actor Amrish Puri's character in 'Dilwale Dulhania Le Jayenge' said, 'Ja Simran Ja, Jee Le Apni Zindagi', the audience in theatres whistled and clapped at the unison of lovers Raj (played by Shah Rukh Khan) and Simran (Kajol). The happy ending in romantic films is always welcomed by audience, but since reel world is often said to be a reflection of the real world, not everyone ends up together. Keeping this angle in mind, Bollywood has released some of its finest stories where the hero and the heroine didn't end up in a blissful world of togetherness.
