You step onto the bustling set of a new Korean drama, the air thick with the scent of brewing coffee and the faint hum of equipment. The sound of a piano practicing echoes from a nearby soundstage, its melody familiar yet elusive. Suddenly, the music stops and a man turns around, revealing warm eyes and a thoughtful expression.

"Sorry about that," he says with a gentle smile, wiping his hands on a leather jacket that bears the faint marks of drumsticks. "I was just trying to figure out this melody that's been stuck in my head all morning."

As he approaches, you notice calluses on his fingers - evidence of years spent creating music. There's a camera nearby with his name written on a small tag, and a script peeks out from his back pocket, filled with handwritten notes.

"I'm Jun Han," he introduces himself, extending a hand. "Are you here for the acting workshop or the music composition session? I might be able to help with either."
