Episode 1 recap: Zhou Xiao Feng and Lin Yi encountered a doctor-patient conflict when they first met.

At the operating room of Dongli Hospital, Zhou Xiao Feng, the deputy chief physician of the cardiology department (played by Zhao You Ting), is performing a heart surgery. Suddenly, Zhou Xiao Feng remembers what the cardiovascular surgeon, Lin Yi (played by Jin Shi Jia), said to him: "If it weren't for the failed surgery, Old Wang would have lived another twenty years."

The story goes back two days. Early in the morning, Lin Yi goes to the market to buy vegetables. Just as she finishes shopping, she notices a middle-aged man sitting on the roadside, feeling uncomfortable. He complains about shortness of breath. Being a doctor, Lin Yi pays attention and starts questioning the man.

Lin Yi notices that the man's heartbeat is very fast. The middle-aged man mentions a previous fracture, and Lin Yi strongly suspects a heart condition. Despite the man's denial and intention to leave, he is unable to proceed alone. Lin Yi kindly takes him to Dongli Hospital. Meanwhile, Zhou Xiao Feng is explaining the upcoming surgery to the patient's family, hoping to inform them about the entire treatment process. The surgery is successful.

Lin Yi brings the middle-aged man to the hospital, and Zhou Xiao Feng happens to receive him. Lin Yi explains the situation to Zhou Xiao Feng, who quickly leaves due to some personal matters. Zhou Xiao Feng plans to examine the elderly patient first. Although Mr. Wang insists that he is fine, Zhou Xiao Feng's examination reveals the possibility of acute myocardial infarction. When Mr. Wang learns that he needs to pay a hospitalization fee of 15,000 yuan, he refuses treatment and even claims that he is in good condition.

After returning home, Lin Yi promptly treats her brother, who is experiencing shortness of breath. Meanwhile, Zhou Xiao Feng receives a nurse's notification that a patient's heart rate is rapidly dropping. Zhou Xiao Feng rushes to the patient and performs emergency rescue. It is too late to transport the patient to the operating room, so Zhou Xiao Feng performs a puncture on the spot and installs a temporary pacemaker, gradually stabilizing the patient's heartbeat.

On the other hand, Lin Yi successfully stabilizes her brother's condition, causing her to sweat profusely. When Zhou Xiao Feng prepares to explain the situation to Mr. Wang, he has quietly left. After finishing her tasks, Lin Yi calls Mr. Wang, but he claims to be fine.

Back at home, Lin Yi receives a call from Lao Cao, inquiring about the medical examination report. Lin Yi is about to start working at Dongli Hospital; previously, she worked at Xili Hospital. Her teacher advises her to do a good job. Fang Xiao Ran (played by Mao Xiao Tong), a physician in the cardiac intensive care unit at Dongli Hospital, interviews and records information from each patient every day.

After finishing her outpatient tasks, Zhou Xiao Feng often visits the intensive care unit. It can be said that Fang Xiao Ran is Zhou Xiao Feng's super fan, sometimes even secretly taking pictures of him while he's working. During the morning meeting, Vice President Cui Jing announces that Zhou Xiao Feng has won the innovation award in the cardiology department for the first time. This time, both the cardiology and cardiovascular surgery departments will be rewarded, and everyone welcomes this news.

Subsequently, Cui Jing introduces Lin Yi to everyone. Lin Yi is considered a genius doctor, and Zhou Xiao Feng immediately realizes that Lin Yi is the person who brought Mr. Wang.

Zhou Xiaofeng quickly asked his colleague Zhang Zhen if there was an elderly Mr. Wang who had come for a follow-up, and told him to hurry up and practice. Zhang Zhen immediately came out of the meeting room to find Mr. Wang.

Zhou Xiaofeng then began to discuss the recent medical conditions, and the cardiology and cardiovascular surgery departments started their daily rounds. Zhang Zhen called and found out that the phone number left by Mr. Wang was incorrect and they couldn't contact him. Zhou Xiaofeng suddenly remembered that Lin Yi might have the correct phone number, so he quickly went to find Lin Yi and ask for Mr. Wang's phone number.

Lin Yi promptly gave the phone number to Zhou Xiaofeng. Zhou Xiaofeng called the number but no one answered. Zhang Zhen called and said they had found the person but he was now in the emergency room. Zhou Xiaofeng and Lin Yi hurried over, but by the time they arrived, Mr. Wang had already stopped breathing. The doctors had been trying to resuscitate him for half an hour, but there was still no response, and they had to declare his death.

Lin Yi questioned Zhou Xiaofeng about how the situation had escalated to this point. Zhou Xiaofeng said that the patient didn't want to cooperate with the treatment and left. Lin Yi wondered why Zhou Xiaofeng didn't keep the patient in such a serious condition, but Zhou Xiaofeng didn't offer an explanation. Lin Yi received a call from Director Jiang asking for help, so she didn't have time to argue with Zhou Xiaofeng and immediately rushed to the operating room.

At this time, everyone was racing against time to start the heart surgery. With Lin Yi's help, they managed to save the patient's life. Now, everyone is questioning Zhou Xiaofeng about Mr. Wang's case, and Zhou Xiaofeng provides an explanation. However, Lin Yi still feels that Zhou Xiaofeng didn't make enough effort to keep the patient. Zhou Xiaofeng didn't even have a chance to mention that he had also been rescuing a patient with a heart attack the previous day.

The son of the deceased is relatively reasonable, but other relatives are more impulsive. Because of this incident, Zhou Xiaofeng also faced accusations. The reason Lin Yi transferred from Xili Hospital to Dongli Hospital was to be closer to home. Mr. Wang's family members confronted Zhou Xiaofeng, and Fang Xiao Ran also stepped in to explain that Mr. Wang's son had fulfilled his duties as a son.
