Original
A young actor met a young reporter when both were getting started in the business. Years later, as the actor is getting to be a big name and the reporter has started working at a more prestigious publication, they reconnect. Slash or het; can do either role for this one.
A fan wins a contest to spend a day with his/her favorite actor. They hit it off surprisingly well and start seeing one another, despite paparazzi and tabloid speculation. Slash or het; would prefer to play the actor.
The son of a media mogul is sent to one of his papers to work undercover and "clean up shop." As he learns more about the news business, he finds himself drawn to it instead of wanting to cut costs. A couple of options for the second role: a reporter who helps teach him the ropes. An employee who figures out his secret and tries to blackmail him. Throw any others at me, too!
