As the situation got worse, Oh Yi-young called Min Eun-won, but she did not pick up. When Min Eun-won finally answered, Oh Yi-young told her they must do a surgery and disconnected immediately.
As Min Eun-won rushed to the patient's room and checked the situation realized they were behind schedule. Min saw the cameras and yelled at Oh for not setting up the OR for the surgery. Min Eun-won advised Oh Yi-young to study hard on camera and asked her to ask for help when needed.

2) Um Jae-il and Kim Sa-bi's experience with fellow medical professionals
In Resident Playbook episode 9, Ki Eun-mi (Lee Do-hye), a 3rd-year resident, got yelled at by a professor due to Um Jae-il's mistake.

He later met the new intern, who made several mistakes due to a lack of knowledge. Um Jae-il went easy on the intern and even did some of his tasks. He soon overheard the intern talking about him at the hospital cafeteria.
The intern thought Um Jae-il was a pushover and made him do all his work. The intern apologized, and Um Jae-il let it go, but he was disheartened deep inside. Later, Ku Do-won explained to him that the intern took his kindness the wrong way.
In contrast, Cha Da-hye (Hong Na-hyun), a second-year resident working under Kim Sa-bi, made continuous calls and double-checked everything to avoid mistakes made by first-year residents.
However, Cha Da-hye spoke in a forceful tone and never responded to Kim Sa-bi's doubts. She even handed her books to get her doubts cleared. In one instance, Kim Sa-bi's and Cha Da-hye's judgments on a patient's diagnosis conflicted.
Cha Da-hye was persistent on waiting the night and taking action after observation the next morning. Kim Sa-bi asked her twice if they should take action immediately, but Cha Da-hye told her to wait. Kim Sa-bi, being impatient, called Professor Jo in the middle of the night. The next morning Professor Jo scolded Cha Da-hye for Kim Sa-bi's actions. Cha Da-hye was eventually correct.
Later, Kim Sa-bi, in Resident Playbook episode 9, apologized to Cha Da-hye. She said that in return she would continue asking her questions so that all her queries would be solved.
