Son Ye-jin
Cha Mi-jo

Leaning on each other through thick and thin, a trio of best friends stand together as they experience life, love and loss on the brink of turning 40.
I have been thinking about how we mark time. The big birthdays are noise. The small shifts are the story.
A friendship that deepens over coffee that turns into confession. A career that used to feel like a sprint and now has no finish line. People will file Thirty-Nine, the 2022 South Korean drama, under turning forty.
The series is more interested in the slow ache of the year before.
It follows three women. Cha Mi-jo, played by Son Ye-jin, is a dermatologist. Jeong Chan-young, played by Jeon Mi-do, is a struggling acting teacher.
Jang Joo-hee, played by Kim Ji-hyun, manages cosmetics in a department store. They move through the unglamorous, often heartbreaking facts of approaching middle age. No single bomb starts the plot. Thirty-Nine unfolds the way a year unfolds.
A missed call. A doctor's appointment. A text left unanswered.
Those are the things that shape them.

The show has little interest in the usual K-drama women. These are not fresh-faced rom-com leads, and they are not stoic suffering mothers. They are allowed to be selfish, scared, and sometimes hard to like.
Mi-jo, the most financially stable, carries family expectations and her own unmet wants. Chan-young, the dreamer, chases an acting career that never quite arrives, and her optimism turns brittle. Joo-hee looks the most put-together and hides a loneliness that leaks into every room.
Netflix’s 2022 Korean drama Thirty-Nine arrived with high expectations, thanks to its star-studded cast and a premise centered on three childhood friends navigating love, careers, and mortality in their late 30s. Headlined by Son Ye-jin (Crash Landing on You), Jeon Mi-do (Hospital Playlist), and Kim Ji-hyun, the series quickly became a talking point—but not always for the reasons fans expected. While its ratings soared, rumors of behind-the-scenes tension and controversy swirled, latestnetflix.com contends, leaving viewers to wonder: Was Thirty-Nine as smooth a production as its trailer suggested?
One of the drama’s biggest draws was its ensemble cast, particularly the dynamic between Son Ye-jin and Jeon Mi-do. Clips from the script-reading session showed the two leads sharing playful banter, fueling speculation about their off-screen friendship. However, not all cast interactions were as seamless. Rumors of friction between Son Ye-jin and another lead, Yeon Woo-jin, surfaced early in the press cycle . While neither actor addressed the claims directly, the timing of the gossip—just as the drama premiered—raised eyebrows. Some fans dismissed it as tabloid noise, but others pointed to the lack of joint promotional appearances as potential evidence of tension.
Adding to the intrigue, sources highlighted that Son Ye-jin and Yeon Woo-jin had worked together before (The Pirates: The Last Royal Treasure), but their chemistry in Thirty-Nine was noticeably subdued. Whether this was a creative choice or a sign of off-screen strain remains unconfirmed.
Ahead of its release, Thirty-Nine found itself at the center of a minor scandal. A video titled "Son Ye-jin’s 'Thirty-Nine' In Controversy?" circulated online, teasing unspecified drama. The clip’s thumbnail and title suggested a major issue—perhaps a script leak, a casting dispute, or even a feud—but the actual content of the video (based on available snippets) never delivered concrete details. Instead, it leaned into vague insinuations, a common tactic for driving engagement.
The drama’s official trailer , which promised a heartfelt story about friendship and aging, offered no hints of behind-the-scenes strife. Yet the controversy narrative persisted, with some outlets framing it as a "ratings ploy" . Whether the buzz was manufactured or rooted in truth, it undeniably boosted early interest in the series.
Despite the noise, Thirty-Nine delivered where it mattered: with audiences. The series earned a solid 7.5/10 rating on SensCritique , with viewers praising its emotional depth and the performances of its leads. Son Ye-jin, in particular, was lauded for her portrayal of Cha Mi-jo, a dermatologist grappling with a terminal diagnosis. Jeon Mi-do’s turn as the free-spirited Jang Joo-hee also resonated, with fans calling her the "heart" of the trio.
Critics, however, were more divided. Some found the pacing uneven, while others felt the romance subplots overshadowed the drama’s more poignant themes. Still, the show’s ability to blend humor and heartache kept it in conversations long after its finale.
With Thirty-Nine now in the rearview, its stars have moved on to new projects—though none have publicly addressed the rumors that dogged the production. Son Ye-jin has since taken on roles in The Glory (2022–2023) and Sweet Home (2020–present), while Jeon Mi-do returned to the medical genre with Doctor Slump (2024). Yeon Woo-jin, meanwhile, has kept a lower profile, fueling speculation about whether the alleged tension played a role in his career trajectory.
For now, Thirty-Nine remains a case study in how a drama’s off-screen narrative can overshadow its on-screen story. Whether the controversy was real or exaggerated, one thing is clear: the series left a mark—not just for its emotional storytelling, but for the questions it left unanswered.
