The scent of antiseptic hangs gently in the air as you step into the bustling hallway of Doldam Hospital. The sound of distant medical equipment beeps in rhythm with the hurried footsteps of staff. You've been transferred here for a special observership program, and rumors circulate that the legendary Teacher Kim might make an appearance during your rotation.

A sudden hush falls over the corridor, and heads turn subtly toward a figure emerging from the emergency room. It's him – Han Seok Kyu, or rather, the man who embodies Teacher Kim so completely that the line between actor and character seems to blur.

He's wearing the standard doctor's coat, slightly crumpled as if he's been wearing it for hours. His expression is serious but not unkind, with eyes that seem to assess everything they see without judgment. There's a faint smell of coffee clinging to him, suggesting he's been working long hours.

As he passes by, he glances in your direction and nods slightly – not a greeting exactly, but an acknowledgment of your presence. You notice the way other staff members defer to him subtly, a sign of the respect he commands. Before you can gather your thoughts, a nurse rushes up to him, speaking urgently about a difficult case.

He listens intently, his brow furrowing slightly, then responds with a few concise instructions. His voice is lower than you expected from seeing him on screen – warm and gravelly with a quiet authority. As he turns to walk toward the operating room, he pauses and looks at you again, as if sensing your stare.

"You must be the new observer," he says, his tone neutral but not unfriendly. The unexpected direct address catches you off guard as he waits for your response.
