The episode opens with Oh Yi-young abruptly waking from a nightmare in which she witnesses a woman dying from postpartum hemorrhage (PPH). The vivid fear from this dream lingers as Yi-young and the other first-year residents attend Professor Seo's class, where the day's lecture is on PPH. Professor Seo sternly reminds the class that they recently lost a patient to this condition, setting a somber and urgent tone for the session.

Meanwhile, Professor Kong, learning about Seo's lecture on PPH, becomes visibly upset because PPH was her specialty just a week prior. She covertly manipulates the surgery schedule by instructing Nam-kyung to schedule her surgery by 3 p.m. and to delay Seo's case until 6 p.m. Nam-kyung, sensing the brewing conflict, collaborates with Yi-young to manage the increasingly chaotic operating room bookings. The tension escalates as it becomes clear that the scheduling conflict is less about patient care and more about a power struggle between Professors Kong and Seo. This pressure causes friction between Yi-young and Nam-kyung, who begin exchanging sharp remarks while trying to satisfy their superiors.

In the hospital corridors, Yi-young and Ku Do-won are shown carefully concealing their romantic relationship. When Oh Joo-young inquires if Yi-young is seeing someone, Yi-young vaguely confirms it is someone from the hospital but then downplays the seriousness by claiming she was joking about marriage. Later, Yi-young and Do-won narrowly avoid being caught by Min Eun-won while together at the hospital, quickly hiding their closeness. Toward the episode's end, Um Jae-il spots Yi-young and Do-won walking hand in hand down a dimly lit corridor, though it remains uncertain if he fully recognizes them.

Back in the hospital, Sa-bi, a first-year resident, grows increasingly frustrated with her senior resident Da-hye, who micromanages her and frequently looks over her shoulder. Sa-bi feels insulted by Da-hye's lack of trust and dismissive attitude, especially when Da-hye fails to provide clear guidance. This tension culminates when Sa-bi becomes concerned about a patient's chart and, after Da-hye insists on waiting until morning, Sa-bi bypasses her to report the issue directly to Professor Jo. Although Da-hye's initial assessment was correct, she is reprimanded for Sa-bi's insubordination. Both Sa-bi and Da-hye reflect on their strained relationship, acknowledging the challenges of trust and responsibility with their limited experience difference.

Sa-bi also faces ongoing public reprimands from her professor for observing an obstetrics surgery despite being a gynecology resident. This professor's petty behavior escalates until the obstetrics professor intervenes, defending Sa-bi and chastising the other professor, which surprises everyone and garners support for Sa-bi. Jae-il and a nurse advise Sa-bi to feign tears to ease the situation, hinting at her possible desire to transfer departments.

Throughout the episode, the residents are caught in the crossfire of their professors' rivalry, which exacerbates their stress and complicates their duties. Yi-young's nightmare and the real loss of a patient to PPH weigh heavily on her, intensifying her emotional burden. The episode closes with the mounting tension among the residents and the secret romance between Yi-young and Do-won becoming increasingly difficult to conceal, setting the stage for further developments.

At the end of Resident Playbook Season 1, Episode 10, the residents face intense professional and personal challenges. Oh Yi-young and Ku Do-won finally acknowledge their secret relationship by holding hands in the hospital corridor, though it remains unclear if others fully realize it. Nam-kyung confronts the death of her first patient, Yeom Mi-so, accepting the harsh realities of medicine. Meanwhile, tensions between residents and professors escalate, but the group begins to mature in their roles as doctors, embracing the difficult balance of life and death in the hospital.

Expanded narrative of the ending scene by scene:

The episode opens with Oh Yi-young waking abruptly from a nightmare where a woman is dying from postpartum hemorrhage (PPH), a traumatic event that haunts her throughout the day. This nightmare sets a somber tone as the first-year residents attend Professor Seo's class, where the topic is PPH--the very condition that recently claimed a patient's life. Professor Seo's stern reminder about the loss underscores the gravity of their work and the stakes involved.

Meanwhile, a power struggle unfolds behind the scenes. Professor Kong, upset that Professor Seo is lecturing on PPH after she had just covered it, manipulates the surgery schedule to assert dominance. She instructs Nam-kyung to schedule her surgery by 3 p.m. and delays Seo's case until 6 p.m. Nam-kyung, caught in the middle, teams up with Yi-young to manage the chaotic operating room bookings. Their collaboration is fraught with tension, as they snap at each other under pressure, reflecting the larger conflict between their superiors rather than patient care.

Sa-bi faces her own challenges, repeatedly reprimanded by her professor for observing an obstetrics surgery despite being a gynecology resident. The professor's petty and public scolding escalates until the obstetrics professor intervenes, defending Sa-bi and turning the tables on the critic. This confrontation highlights the departmental politics and the struggles residents face beyond medical duties. Jae-il quietly supports Sa-bi, hinting at a growing bond between them.

In the hospital corridors, Yi-young and Do-won carefully conceal their budding romance. When asked by Oh Joo-young about her relationship status, Yi-young hints at someone from the hospital but denies seriousness when pressed. Later, they nearly get caught by Min Eun-won but manage to hide their closeness. The episode closes with Um Jae-il spotting Yi-young and Do-won walking hand in hand, though the dim lighting leaves it ambiguous whether he fully recognizes them.

The emotional climax centers on Nam-kyung's experience with Yeom Mi-so, her first patient at Yulje Hospital. Mi-so is dying on New Year's Eve, and Nam-kyung stays by her side, confirming a Do Not Resuscitate order and playing Mi-so's favorite hymn as she slips away. This moment is raw and intimate, showing Nam-kyung's vulnerability as she breaks down after filling out the death certificate. Yet, the hospital's relentless pace forces her to compose herself quickly when a patient in active labor arrives, symbolizing the continuous cycle of life and death that defines their work.

The episode ends on this poignant note: the residents, who began the season fearful and hesitant, are now confronting the realities of their profession with growing resilience. Nam-kyung accepts that sometimes saving a patient is impossible, and the others are learning to navigate the complex dynamics of hospital life, both personal and professional. Yi-young and Do-won's secret relationship adds a tender human element amid the clinical challenges, while Sa-bi and Jae-il's interactions suggest new emotional developments.

In summary, the fate of the main characters at the end of Episode 10 is:

• Oh Yi-young and Ku Do-won: Secretly together, cautiously navigating their relationship within the hospital environment.
• Nam-kyung: Faces the death of her first patient, growing in emotional maturity and acceptance of medical realities.
• Sa-bi: Continues to struggle with departmental politics but gains support from peers and possibly considers shifting her path.
• Jae-il: Shows protective and caring feelings toward Sa-bi and becomes aware of Yi-young and Do-won's relationship.

The episode closes with the message that life in the hospital is a continuous, challenging cycle of loss and hope, and the residents are beginning to find their footing within it.

Yes, Resident Playbook Season 1, Episode 10 does have a post-credit scene. In this scene, Ik-Joon and Song-Hwa are walking through a dark, deserted outpatient hallway in the hospital, which Ik-Joon describes as a secret spot where hospital staff come to date discreetly. He refers to the couples as "cockroaches" because they quickly scatter if someone unexpectedly appears. As Ik-Joon and Song-Hwa leave, Jae-il and Sa-bi emerge from hiding nearby. Sa-bi questions why Jae-il made her hide when they are not dating, hinting at some romantic tension between them. Then, when Jae-il returns to retrieve his lab coat, he unexpectedly sees Oh Yi-young and Ku Do-won exiting a room holding hands, revealing their secret relationship. Jae-il realizes they are dating, but they do not know that he knows yet.

Oh Yi-young's nightmare about a woman dying from postpartum hemorrhage (PPH) sets a haunting and grave tone for Episode 10. It reflects her trauma and guilt after witnessing a patient die from excessive blood loss, which deeply affects her emotionally and mentally throughout the episode. This nightmare also foreshadows the episode's focus on PPH during Professor Seo's class and highlights the high stakes and pressures the residents face in handling such critical cases.

The conflict between Professor Seo and Professor Kong creates a tense 'turf war' that directly impacts the residents, especially Oh Yi-young and Nam-kyung. Professor Kong manipulates the surgery schedule to prioritize her cases over Seo's, forcing Nam-kyung and Yi-young to juggle operating room bookings under pressure. This rivalry causes friction and sniping between the two residents as they struggle to manage their duties while navigating the professors' power struggle.

In Episode 10, Oh Yi-young and Ku Do-won begin a secret romantic relationship within the hospital. They are cautious about keeping it hidden, especially from colleagues like Min Eun-won.

Their romance adds a personal and emotional subplot to the episode.

Oh Yi-young and Nam-kyung experience increasing tension and conflict throughout Episode 10. They are forced to work closely together to manage the complicated surgery schedule amid the professors' rivalry, but their stress leads to frequent sniping and clashes. Their strained relationship reflects the broader challenges the residents face in balancing professional responsibilities with interpersonal dynamics under pressure.

Sa-bi struggles with Da-hye's micromanagement and perceived lack of trust, which frustrates her. When Sa-bi becomes concerned about a patient's chart, she bypasses Da-hye to report to Professor Jo, leading to Da-hye being reprimanded despite her correct assessment. This incident highlights the mutual lack of trust and communication issues between the two residents, underscoring the difficulties of hierarchy and responsibility within the hospital setting.
