Where Episode 3 Left Off?
In the last episode, Gye Soo Jung averted a tragedy using her sharp powers of observation and exceptional surgical skills. Her talent is clear, but her position is still uncertain. Jang Hee Sook (Lee Jung Eun) pushed for a formal contract for her. Boo Seung Kwon (Son Hyun Joo) put the proposal on hold, announcing that he had hired a new surgeon, Na Dae Il (Jang Seung Jo). It’s a pointed move, and it suggests the hospital may be testing her.

Meet Na Dae Il
The newcomer arrives with a very different style from Soo Jung. In Episode 4, Na Dae Il launches a charm offensive to win over the aloof surgeon. Where she is blunt and guarded, he is friendly and warm, which makes the pairing a fun contrast.
The Coffee-and-Bread Scene
The new stills show his first attempt. He visits her at the emergency room front desk with coffee and bread, smiling and trying to start a conversation. The twist is that Soo Jung usually reacts to food with open excitement, yet this time she stays stoic. She keeps an indifferent expression and doesn’t even glance at the gift. If she’d turn down food, she clearly doesn’t trust him.
Is Something Hidden Behind That Smile?
The drama hints that there’s more going on. Viewers will find out what hidden motives Na Dae Il has for approaching her, and how she reacts to his suspicious behavior. Is he a rival, a spy for the hospital, or a genuine ally? The preview leaves it open, and that mystery adds tension.
Why Watch?
Medical noir works best when skill meets politics, and this show does both. Kim Ji Won plays a surgeon who lets her results speak, while the hospital’s power plays keep trying to box her in. With a charming new face entering the picture, Episode 4 promises sharper conflict and a few laughs. If you want more from the cast, you can watch Jang Seung Jo in Strangers Again and Kim Ji Won in Fight for My Way on Viki.
