I searched his profile on Wikipedia and he doesn't seem to have done any significant work in his career, however brief it is. He has mostly been cast in mythological shows but I don't they were all that popular that he managed to gain so many fans. Above all, he's a mediocre actor at best. So is Meera.
I hadn't even seen or heard of VJ before tuning in to Udaan and it took me only a moment to realize what a brilliant actor he is. Which is also the reason why I was left completely baffled when I realized Paras was one of the leads. And there is no bias in my opinion because I was unaware of both VJ and Paras before this show. My opinion is solely based on my observation of watching their scenes and after just one episode, I could easily declare VJ to be the better actor, both in talent and charisma.
So back to my original question, why is Paras so famous?
