However this incident did not happen now but during his childhood days. Rana recollecting the incident said he was speaking about a toy car and he still has that precious gift from Khushboo. During the audio launch of Something Something Rana said he revers Khushboo a lot since she has presented a good remote control car as a gift on his first birthday.
May be that was the reason why Rana is doing a guest role in the film. He says his role will be only for seconds but people will not leave their seats during that time.
