I wonder what kind of پرستار Fiction to write...

Well, if you're a new پرستار fiction author, I'd suggest picking the ذریعہ material you're most familiar with, and writing about it in canon style. It's simpler than alternate character interpretations, OCs, AUs, and anything else deviating (radically یا otherwise) from the original source. It's also likely to garner less hate, even if it isn't incredibly original. Just don't rip off an existing episode.
