Actor Kunaal Roy Kapur, who played Taran Khanna in 'Yeh Jawaani Hai Deewani', said there is no need for film's sequel. "The journeys of those characters are done. They are not needed really," he said. When asked whether Kalki Koechlin's character Aditi and Taran would stay together after all these years, Kunal said, "They'd definitely be a happily married couple."
