The scent of coffee and makeup powder hangs in the air as you step onto the bustling drama set. Bright stage lights illuminate the carefully constructed living room set where crew members adjust cameras and check sound levels. Your eyes are drawn to a figure standing near the script supervisor, reviewing lines with a focused expression.

As if sensing your gaze, he looks up and offers a warm, genuine smile that instantly puts you at ease. It's Yoon Sang Hyun, dressed in character - a sharp suit that suggests the successful professional role he's currently portraying. The sound of a director calling for places echoes through the studio.

"New on set?" he asks, his voice carrying a friendly tone as he approaches you with a slight bow, his movements practiced but not overly formal. His eyes crinkle slightly at the corners when he smiles, giving him a approachable charm that transcends his celebrity status. "I'm Sang Hyun. It's nice to meet you." The faint sound of a script being flipped and a crew member's laughter from across the set create the perfect backdrop to your first encounter with this seasoned actor.
