Doctor Slump (TV series)

Main

• Park Hyung-sik as Yeo Jeong-woo
  • Seo Woo-jin as young Yeo Jeong-woo

A plastic surgeon who achieved academic and professional success early in life due to his academic aptitude, graduating from South Korea's top medical school and gaining public recognition through a documentary about his overseas volunteer work performing reconstructive surgeries. He views plastic surgery as a means to improve patients' self-esteem and quality of life, a philosophy that helped him build a prominent public profile and co-found a medical YouTube channel that earned a Gold Creator Award. However, his career faces a crisis when a patient dies during a facial contouring surgery under mysterious circumstances, complicated by the unexplained failure of the operating room's CCTV cameras during the procedure. Struggling to cope with the sudden downfall and seeking escape from public scrutiny, he unexpectedly reunites with Ha-neul, his intense academic rival from his school years.^[1]

• Park Shin-hye as Nam Ha-neul
  • Yu Ha-yeon as young Nam Ha-neul

An anesthesiologist who was recognized as an academic prodigy from a young age in Busan, consistently ranking at the top of her school through extreme, self-sacrificing study habits and eventually scoring first in the nation on a high school mock examination. Driven by a strong competitive nature and the belief that temporary self-deprivation would secure her future happiness, she eschewed social relationships and leisure to focus entirely on her education, leading her family to relocate to Seoul where she encountered her academic rival, Jeong-woo, before successfully entering medical school. Despite achieving her goal of becoming a doctor, the prolonged psychological strain and lack of work-life balance eventually cause her to experience severe burnout, prompting her to abruptly resign from her position to re-evaluate her life. Unaccustomed to leisure and struggling to adapt to free time, her routine shifts when Jeong-woo unexpectedly moves into the rooftop apartment of her family's building. Although they initially resume their high school animosity, Ha-neul develops empathy for Jeong-woo upon witnessing his night terrors and isolating legal battles stemming from a mysterious medical malpractice incident, leading her to provide emotional and legal support while he teaches her how to relax, which gradually transitions their rivalry into mutual romantic interest.^[2]

• Yoon Park as Bin Dae-yeong

A plastic surgeon running La Beaute Plastic Surgery Clinic in Gangnam, though his practice struggles financially despite his attempts to attract patients through billboard advertisements and a personal lifestyle vlog on YouTube. As a university classmate who is older than Jeong-woo due to entering medical school late, Dae-yeong harbors a complex mix of envy and affection toward his more successful peer; though he initially leaves malicious online comments out of jealousy rooted in a past misunderstanding from their college days, he defends Jeong-woo against public backlash and assists in his eventual professional return after Jeong-woo's downfall. Additionally, Dae-yeong is a single father raising a middle-school-aged daughter following a difficult divorce from his wealthy ex-wife, whose family subjected him to demanding personal requests. While struggling with the challenges of raising a teenage daughter alone, he develops a mutual support system with Hong-ran, a neighboring gynecologist who helps him navigate parenting dilemmas while he assists with her young son.^[3]

• Kong Seong-ha [ko] as Lee Hong-ran

An obstetrician and gynecologist, a university classmate of Ha-neul, and her closest friend since their residency. She is a divorced single mother raising her six-year-old son, struggles to balance her demanding medical career—which involves frequent night calls—with her efforts to fill the absence of a father for her child. Due to her schedule, her mother cares for her son during the week, while Hong-ran takes over on weekends, often finding herself unable to fulfill certain requests like taking him to gender-segregated public baths or participating in activities she dislikes, such as insect collecting. Despite her heavy drinking habits and aggressive socialization style, she was the one who initially initiated contact with the solitary Ha-neul, forming a lasting bond. In her professional vicinity, she repeatedly crosses paths with Dae-young, a divorced plastic surgeon operating a clinic across from hers, after discovering his YouTube channel and experiencing an accidental introduction that eventually leads them to support each other through their respective personal shortcomings.^[4]

• Oh Dong-min [ko] as Min Kyung-min

A medical professional who shares close connections with both Jeong-woo and Ha-neul. He originally met Jeong-woo while working as his medical student tutor during Jeong-woo's senior year of high school, eventually becoming a close, familial figure to him and later working dedicatedly to help clear Jeong-woo's name following his medical malpractice crisis. Professionally, Kyung-min also served as a hospital senior to Ha-neul and Hong-ran during their residency. Due to his kind demeanor and professional competence, he earned the deep respect of the otherwise reserved Ha-neul, leading others to perceive a romantic connection between them and leaving Ha-neul with lasting memories of their past interactions.^[5]

Supporting

Ha-neul's family

• Jang Hye-jin as Kong Wol-seon

A single mother who gave birth to her daughter, Ha-neul, at nineteen, and values the youthful, close relationship she shares with her children while living with her late husband's family. Her primary source of pride and fulfillment is Ha-neul's career as a doctor, which helps mitigate other family stressors, including her late husband's absence and her nearly thirty-year-old son's prolonged unemployment. However, Wol-seon faces an emotional challenge when Ha-neul is diagnosed with depression, transitioning from initial denial to acceptance as she focuses on supporting her daughter's mental health recovery.^[6]

• Yoon Sang-hyeon as Nam Ba-da

Ha-neul's younger brother. Unlike his academically successful sister, Ba-da possesses neither an aptitude nor an interest in studying, operating under the belief that one top student per household is sufficient. Officially an unemployed job seeker, he lacks the ambition to find employment and instead hopes to inherit his mother's building to live comfortably, maintaining a cheerful attitude despite regular criticism from his mother and sister. To attract romantic interest, he intentionally alters his dialect depending on whether he is speaking to women from Seoul or Busan. Following Ha-neul's burnout and subsequent unemployment, Ba-da finds amusement in the situation, jokingly arguing that he is the more dutiful child for never raising their family's expectations in the first place.^[6]

• Hyun Bong-sik as Kong Tae-seon

Ha-neul's maternal uncle, who runs a milmyeon restaurant on the ground floor of their building after learning the craft as a kitchen assistant at a top restaurant in Busan. Despite his imposing build and strong regional dialect, he is dedicated to his business, maintaining strict quality controls such as refusing to offer delivery to prevent the noodles from getting soggy.

Development and casting

The development of Doctor Slump began under the direction of Oh Hyun-jong [ko], known for his work on Weightlifting Fairy Kim Bok-joo (2016), and writer Baek Seon-woo [ko], whose previous credits include What's Wrong with Secretary Kim (2018). Produced by SLL and HighZium Studio, the series was envisioned as a "medical-human" drama that focused more on the psychological recovery and "slump" of its protagonists rather than traditional hospital politics.^[9] The project was initially slated for an October 2023 release on JTBC but was later moved to the first quarter of 2024 to anchor the network's weekend lineup.^[10] The first script reading was held on March 4, 2023, where the creative team established the show's tone as a blend of nostalgic romantic comedy and modern-day healing drama.^[11]

Casting garnered significant media interest as it marked the first on-screen reunion between leads Park Shin-hye and Park Hyung-sik in eleven years, following their roles in the 2013 teen drama The Heirs. The project also served as a high-profile comeback for Park Shin-hye, marking her return to the screen after a two-year hiatus following her marriage and the birth of her first child.^[12] By March 2023, the main cast was rounded out by Yoon Park and Kong Seong-ha [ko], who were cast to portray the secondary lead couple.^[13] Park Won-sang and Lee Sung-kyung were cast to make a special appearances.^[14][15] Lee's casting was due to her professional relationship with director Oh, with whom she previously worked on the 2016–2017 MBC TV series Weightlifting Fairy Kim Bok-joo.^[15]

Filming

Principal photography took place between March and October 2023.^[10][16] To capture the contrast between the characters' past academic success and their present-day struggles, the production utilized a mix of historic and scenic locations across South Korea. The high school flashback sequences were filmed at the historic Choong Ang High School [ko] in Seoul. To emphasize the "healing" theme of the series, several pivotal scenes were shot in nature-centric locations, including the Samyang Roundhill ranch in Pyeongchang, as well as the coastal areas of Gaetmaeul Beach and Yongho Starlight Park in Busan.^[17] Campus settings in Soonchunhyang University in Asan served as the spring backdrop for multiple sequences; the staircase next to the Hakseongsa Hall 2 dormitory was used for the scene where the characters share their drunken confessions, while the school's cherry blossom-lined Phoenix Square was the site of their high school racing scene.^[18] Urban filming took place at various landmarks in Seoul, such as the Deoksugung Palace Stone-wall Road and the Yeouido Saetgang Ecological Park [ko] bridge, providing a grounded, contemporary atmosphere for the characters' adult lives.^[17]

South Korean media critics focused heavily on the show's relatability and its depiction of "mental wounds". Ilgan Sports noted that the series effectively used the irony of doctors—who are typically viewed as "healers"—struggling to care for their own mental health to create a deep sense of empathy with the audience. The review highlighted that the transition from academic competition to mutual comfort felt realistic to viewers who have experienced South Korea's high-pressure work culture.^[33] In a comprehensive review by Maeil Business Newspaper, the series was described as a "sunshine-like drama" amidst a flood of provocative content, though it was criticized for relying on a "predictable romance" as the primary cure for professional burnout.^[34]

Internationally, the series received generally positive reviews, with particular praise directed at the chemistry between the lead actors. On the review aggregator website Rotten Tomatoes, 100% of 6 critics' reviews are positive, with an average rating of 7.2/10.^[28] Writing for Decider, Johnny Loftus gave a "Stream It" recommendation and noted that the lifelong rivalry between Park Shin-hye and Park Hyung-sik provided a compelling foundation for the evolving romance.^[35] S. Poorvaja of The Hindu echoed this sentiment, stating that the lead performances and the show's sensitivity largely compensated for its inconsistent pacing.^[36] While Nandini Iyengar of Bollywood Hungama lauded the "funny yet strong leads",^[37] and Pierce Conrad of the South China Morning Post offered a more tempered assessment, praising Park Shin-hye's "balanced and grounded" performance but felt that Park Hyung-sik's more "showy" portrayal occasionally bordered on caricature.^[32]

Critics were divided regarding the show's narrative focus and its handling of mental health. Tanu I. Raj of NME and Joly Herman of Common Sense Media both awarded the series three out of five stars, describing it as a "fast-paced" and "catchy" watch driven by witty banter.^[30][31] However, Raj observed that the writing occasionally diluted the story's impactful and realistic treatment of mental health.^[31] This sentiment was shared by Conrad, who argued that the series failed to fulfil its promise of addressing the stigmas surrounding mental health in South Korean society, focusing instead on the central romance.^[32] Sarah Musnicky of But Why Tho? gave the series a 6.5/10 rating, criticizing the plot as "directionless" and suggesting that the show's primary messaging became "muddied" as it struggled to find its footing.^[29]
