Episode 6 of "Resident Playbook" unfolds with the residents meticulously organizing their weekly shift rotations. I-yeong's spirits dampen as she finds herself assigned to a different shift from Do-won, while Nam-kyung gently but firmly reminds Jae-il of his obligation to reciprocate her shift coverage next month. However, Sa-bi interrupts, asserting that Jae-il ought to settle his debt within the current month. Their contrasting temperaments quickly escalate into a frequent and fiery exchange of barbs.
Later, as Nam-kyung releases her frustrations about Sa-bi to her first patient of the day, cautiously omitting names, fate plays a cruel trick—Sa-bi inadvertently eavesdrops on the entire conversation upon her arrival for her rounds. The air thickens with unspoken tension.
Elsewhere, Ju-yeong, I-yeong's sister, undertakes her final attempt at conceiving through a fertility clinic, her heart brimming with hope. Tragically, the embryos fail to thrive, rendering the procedure unsuccessful. The news shatters Ju-yeong, whose dream of becoming a mother crumbles into heart-wrenching disappointment.
Meanwhile, Jae-il's patient, a mother-to-be, returns for another ultrasound, her anxiety about her baby's wellbeing palpable. In a separate scene, Do-won and I-yeong share a companionship as they walk home together. Yet, Do-won's serene mood is abruptly shattered by a call from Dr. Myeong, informing him that his credit on their research paper has been demoted from first to second author, justified by the necessity of a rewrite. The blow casts a shadow over their otherwise harmonious moment.
Though clearly troubled, Do-won elects to remain tight-lipped. The ensuing day unveils another blow: Dr. Myeong neglected to mention their paper's selection for an impending conference. As fate would have it, I-yeong's patient soon goes into labor, amidst concerns that had already prompted the medical team to caution her husband about potential excessive blood loss. Should a crucial procedure falter, a hysterectomy might become inevitable, a harrowing prospect that evokes an emotional upheaval in the devoted spouse, renowned for his doting nature around the hospital corridors.
Mercifully, the surgical team's adept handling averts the dire necessity, stemming the bleeding without resorting to the drastic measure. The husband, relieved beyond measure, pours out his gratitude. However, upon his wife's revival, his revelation of a desire for another child prompts a torrent of colorful curses, relayed through I-yeong with venomous venom.
Elsewhere, Jae-il's anxious patient reappears, seeking solace yet again in another ultrasound. Seizing the moment after his senior's departure, Jae-il offers a meticulous and soothing scan, dispelling her lingering fears. Yet, days later, she insists on his presence during a routine check-up. This time, Jae-il spots a worrisome blood vessel and swiftly alerts Professor Seo. The diagnosis: a uterine tear, necessitating immediate surgery. Thanks to Jae-il's vigilant eyes, both mother and child are rescued from impending doom. Later, the grateful patient presents a gift to Jae-il, only to find him in the nursery, where serendipity introduces him to Dr. Jang Hong-do from the Cardiovascular Surgery department.
Meanwhile, the tensions simmering between Nam-kyung and Sa-bi reached a boiling point, causing Nam-kyung to inadvertently miss a long-awaited rendezvous with her seven-year-old boyfriend. Torn between hope and doubt, she hastily made her way to the café, only to be ensnared by the demands of her job and Sa-bi's reluctant grip that wouldn't let her go.
Later, Sa-bi sought out Do-won, determined to resolve the lingering issues. She tracked Nam-kyung down at a nearby convenience store, where she candidly laid bare both their shortcomings and hers, offering a heartfelt apology. Moved by the gesture, Nam-kyung returned the sentiment with an apology of her own.
As part of her residency, I-yeong was tasked with attending a medical conference where Dr. Myeong was set to present a paper largely authored by Do-won. Do-won too was mandated to be present. Despite Dr. Myeong's attempted excuses, I-yeong, who had overheard their exchange, confronted her directly, insisting on an apology to Do-won. Reluctantly, Dr. Myeong complied before departing.
In the closing scenes, Do-won and I-yeong shared a tranquil moment together. Do-won was entertained by I-yeong's animated retelling of the curses her patient had entrusted her to convey to the husband. As they shared laughter, it became evident that Do-won was beginning to thaw towards I-yeong's affections, bringing the episode to a heartwarming close.
