In the bustling corridors of Geosan University Medical Center, a dedicated doctor finds an unexpected patient in a deeply troubled boy. Intern Gang Dong-ju lends his assistance to Dr. Yun Seo-jeong, working alongside her to navigate the dem…

Dong-ju contemplates whether diligence alone guarantees advancement. Doldam Hospital welcomes a new physician specializing in general surgery. Seo-jeong encounters a face from her past.

Despite a deep respect for Teacher Kim’s remarkable abilities, Dong-ju harbors doubts about his methods. Meanwhile, Seo-jeong finds herself confronting the consequences of her choices.

Dong-ju recognized early on that he was simply outmatched by Teacher Kim, and a growing desperation to escape began to take hold. Meanwhile, Doldam received a visit from a distinguished guest. And Seo-jeong found herself taking on a new res…

The definition of principle can shift depending on the circumstances. In the aftermath of a significant highway accident, everyone must contribute. Dong-ju seeks to uncover more about the enigmatic Teacher Kim.

Teacher Kim operates under a strict personal code. Myeong-sim demonstrates the proper way of conducting oneself to the other staff. Colleagues from Seoul make a visit to Doldam. In-beom makes a decisive, instinctive decision.

A sudden surprise ripples through Doldam, and each resident navigates its impact in their own way. Dong-ju seeks clarity, a sense of his place within the unfolding events. Teacher Kim, too, finds himself with a desired outcome, though perha…

The patient always comes first, above all else. Seo-jeong receives an unexpected surge of encouragement. Teacher Kim’s kindness reveals itself to be profoundly complex.

Dong-ju placed a call to Chairman Shin. Meanwhile, Teacher Kim gently reminded Yun-wan of the necessity of fundamental principles. Seo-jeong, in a moment of frustration, troubled an old acquaintance. The day was Friday at Doldam.

An inspector from Geosan attempted to halt the Doldam staff's patient care. However, their efforts were interrupted by a multi-vehicle accident – a scene complicated by the presence of a driver under the influence.

Yun-wan seeks reassurance of Dong-ju’s loyalty. A soldier has vanished. Seo-jeong remains resolute, yet Teacher Kim demonstrates a more effective approach.

Misguided counsel leads Dong-ju to a difficult reckoning. Seo-jeong finds herself unexpectedly challenged. Yun-wan intensifies the tension, but Teacher Kim offers resistance.

As Chairman Shin's surgery looms, the staff begins their meticulous preparations, and Seo-jeong finds herself with a pivotal opportunity. A potential outbreak threatens to engulf Doldam.

Seo-jeong offered her assistance to the most demanding patient. Doldam skillfully averted a potential disaster. Dong-ju expressed his gratitude. Teacher Kim gently corrected In-beom’s error.

Within a world warped by its own rigid demands, genuine integrity and true skill are unwelcome. Shin’s surgery takes a turn for the worse.

Teacher Kim is embarking on a seemingly insurmountable task, and Yun-wan will stop at nothing to prevent it. In-beom, however, desires the surgery – not for his father, but for the good of the entire team.

Outside the operating room, a crowd had gathered, though not all present wished for a favorable outcome. Meanwhile, a suspicious reporter began to circulate near Doldam.

The significance of life’s small occurrences often reveals itself only with the passage of time. Finally, Yun-wan secures his desired outcome: the closure of Doldam.

Yun-wan refuses to let old hurts fade into silence, persistently revisiting them. The tenacious reporter continues his discreet inquiries. Dong-ju directly challenges Teacher Kim regarding events of the past.

Teacher Kim organized a trip to Seoul for the staff. Yun-wan was determined to prevent his former rival from gaining attention. Bu Yong-ju felt a sting of disappointment, yet remained steadfast in his commitment to love and his own convicti…
