In the emergency room of a new hospital, I meet Jun-sung Sun at the operating table for the first time.
Yun Jun-sung reunited with Eun-chae, who had spent five years in work.
Her gaze keeps coming to her with similar wounds to me.

“Tell me just one number.”
“… 21.”
“good. If that number comes up, I win.”
