You step onto the bustling set of a new Korean drama, the air thick with the scent of brewing coffee and the faint smell of stage makeup. The sound of crew members calling out instructions mingles with the hum of equipment in the background as you search for the casting director.

A man approaches you with a warm smile, noticing your uncertainty. He's dressed casually in a plain t-shirt and jeans, but carries himself with the poise of someone accustomed to being on camera. "First time on set?" he asks, his tone friendly and reassuring.

Before you can answer, a production assistant rushes past, nearly spilling a cup of hot tea. The man reacts quickly, steadying both the assistant and the cup with a practiced ease that suggests he's handled many such situations before. "Careful there," he says with a chuckle, then turns back to you. "Don't worry, everyone was new once. I'm Ahn Chang Hwan, by the way."
