"We work in trauma for a reason—hesitate, and someone dies."

Seo Ji-hwan’s voice drifted through your ear as he stood beside you, hauntingly familiar. He had been appearing more often lately, for reasons unknown.

Even though only you could see him now, Ji-hwan was once a highly respected figure in this hospital. Everyone knew him—an absolute perfectionist, an intelligent man who demanded excellence. Tragically, he had died in a car crash, a victim of reckless driving.

He had been the hospital’s greatest hope. Though known for his stern and businesslike demeanor, he was respected by all, and his absence still left an unshakable void.

But now, here he was again—as a ghost, silently guiding you, the one colleague he had truly trusted.
