Netflix Greenlights “First Doctor” as Korean TV Leans Into High-Concept Medical and Action Drama

Netflix has officially confirmed production of “First Doctor”, a new Korean original series centered on pediatric surgery—just as competing networks continue to lean into big-genre programming and character-driven hooks. Meanwhile, MBC has unveiled the first look at “A Bona fide Killer”, an action drama starring Kong Hyo Jin as a working mother and legendary sniper, while JTBC announced a temporary pause in filming for “Rediscovery of Love.” Together, the updates point to a crowded 2026 slate where casting, concept, and production timing are increasingly decisive.

Netflix commits to a pediatric-frontline medical drama

According to Netflix’s announcement highlighted by Soompi, “First Doctor” is set to begin filming in the second half of 2026. The series is built around a medical crisis: a pediatric surgery department facing closure, and the physician at the center of the fight to keep it alive.

Jung Ryeo Won plays Heo Ji Wan, a pediatric surgery professor with exceptional skills and a blunt, straight-talking reputation that earns her the label of a “troublemaker” within the hospital. The character’s defining conflict arrives after an unexpected incident forces her to return to Yeonhwa University Hospital, where she must protect both children’s futures and the department itself.

Opposing her is Ha Yun Kyung as Ki Eun Gyeol, a bold and sharp third-year resident who develops a tense rivalry with Heo Ji Wan. The show’s interpersonal engine—mentor-mentee chemistry that’s constantly undercut by clashing methods—adds tension beyond the operating-room stakes.

A star-studded cast adds institutional weight

Netflix also confirmed a broad supporting lineup designed to make the hospital feel like a fully functioning ecosystem rather than a single-problem set piece. Baek Hyun Jin takes the role of Son Sang Baek, head of surgery, while Kim Jong Soo plays Lee Chang Gon, the hospital’s vice director.

The cast expands further with Kim Moo Yul as Bae Su Wol, a professor of anesthesiology and pain medicine who is described as friendly and good-natured—and a long-time colleague and acquaintance to Heo Ji Wan. Notably, Soompi notes this is the actor’s third collaboration with director Hong Jong Chan, following “Juvenile Justice” and Netflix’s “Teach You A Lesson.”

For Netflix, the pitch is clear: combine a high-stakes specialty (pediatric surgery) with a human-focused mandate (saving a department, saving patients) and anchor it with recognizable performances. With filming slated later in 2026, the production is also positioned to capitalize on viewers’ ongoing appetite for prestige dramas that mix emotional pressure with procedural expertise.

MBC’s “A Bona fide Killer” turns work-life balance into an action premise

While Netflix is committing to medical drama, MBC is pushing a different kind of intensity. “A Bona fide Killer” (working title) has released a first glimpse of Kong Hyo Jin in character, introducing Yu Bo Na, a working mother who leads a double life.

The series frames her dual identity as both relatable and dangerous. By day, Yu Bo Na is a manager of Sales Team 3 at Durumi Electronics. By night—and after a three-year parental leave—she returns to being a legendary sniper known as “Kingfisher.” The action is not presented as escapist fantasy so much as an extension of her daily burdens: trying to maintain work-life balance while moving between family responsibilities and lethal field missions.

Soompi reports that the newly released stills emphasize the contrast. One image shows Yu Bo Na aiming a sniper rifle with a cold gaze, while another depicts her focused at the office with the composure of a top performer. At home, she’s described as warm and approachable—caring for her husband and daughter and wearing a smile rather than the killer persona.

“A Bona fide Killer” is scheduled to premiere on July 31 at 9:50 p.m. KST, positioning it as a summer alternative for viewers who want action wrapped in domestic realism.

But not every production timeline is smooth

Even as networks announce major projects, the business realities of television production remain visible. JTBC’s “Rediscovery of Love” has temporarily halted filming, according to Soompi. The production team said it would take a one-month break to revise and improve the script, and pointed to seasonal conditions—specifically that it is the rainy season—as part of the reasoning behind rescheduling.

Starring Kim So Yeon and Kim Ji Suk, the series follows a divorced couple who end up living in a share house and working at the same hotel, where their lives become entangled again. While the drama’s release plans remain oriented toward the second half of the year, the pause underscores how even high-visibility casts can be affected by creative adjustments.

In a market where attention is increasingly tied to first impressions—trailers, casting announcements, and early story promise—the willingness to delay for script work suggests producers want fewer missteps later, even at the cost of schedule certainty.

What viewers should watch next

For “First Doctor,” the coming months will likely focus on additional casting, character-specific teasers, and how the show plans to treat pediatric care with both emotional depth and procedural credibility. Since filming is set to start in late 2026, early momentum will depend on Netflix’s ability to define the series’ tone—whether it leans more toward courtroom-level conflict, hospital politics, or family-centered doctor drama.

For “A Bona fide Killer,” the next milestone is promotional buildup ahead of its July premiere, particularly how Kong Hyo Jin’s dual portrayal translates into action set pieces that don’t erase the domestic stakes. And for “Rediscovery of Love,” the key question will be whether the script revisions translate into a more compelling hook—and whether the production can return on schedule after the one-month restart.

Taken together, today’s announcements show Korean TV continuing to double down on genre ambition—medical prestige and action-with-feelings alike—while also signaling that creative refinement and timing are critical as more platforms compete for the same audience attention.
