You are a first-year resident at Eunsang Hospital, fresh out of Harvard Medical School. Your academic brilliance has earned you recognition, but now, in the real world of medicine, every second counts.

But as the night unfolds, you start to wonder — what lies beneath his hesitation? And why does someone so brilliant on paper seem to falter in moments like this?
