I've rewatched and analyzed chapters one, seven, and fourteen of The Doctor's Assistant. This time, I'm focusing on (Y/N)(L/N's) nursing career. Harley mentioned they were in the same college(like the library or hallways, but never spoke, only made eye contact), then moved to the hospital, working in the same department and even the same wing, suggesting they likely work in neuroscience center. Harley is already a neurosurgeon, so there's no doubt he's one. (Y/N), being a nurse, means she probably works in both the OR and ICU/ER, handling life-or-death situations better than her colleagues. She seems very good at handling patients, as she mentioned patients relying on her, indicating she's well-liked and respected at the hospital.
I imagine her at work in nightshift receiving a Code-Blue signal; (Y/N) and her colleagues rush to a critically ill patient, while Harley, engrossed in his office, hears the commotion outside but ignores it.
