There is no such love story. We first need to have a real - world existence of Chiranjeevi's daughter named Sushmita. But currently, there is no such information, so no love story exists in this regard.
There are no reports or information in the public regarding the love story of Chiranjeevi's daughter. It is likely that they are leading normal lives away from the public eye and their personal relationships, especially love stories, are not made public.
Since I have no information about this chiranjeevi and meghana love story, it might be a very personal or local story. Maybe you could give some more details like where they are from or some key events in their relationship to help me answer better.
If Chiranjeevi is a public figure, one possible aspect could be that his love story started in his early career days. He might have met his love interest on a movie set or at an industry event. Maybe they were initially friends and then gradually realized their deeper feelings for each other.
I'm not sure which specific 'Chiranjeevi' you are referring to. There could be many people with this name. If it's a well - known actor, for example, more details about his personal love story might be private and not fully disclosed in the public domain.
