Six years ago, Mi-kyung, who was in a workplace romance at Wonjin Retail, lost both love and her job due to her boyfriend’s betrayal and impulsively ran away to her younger brother’s guesthouse. One day, while researching potatoes in the fresh air of Daegwallyeong, news comes that Seonnyeo Foods is acquired by Wonjin Retail, and an attractive yet cold-hearted figure, Baek-ho, is appointed as the new head of the Potato Research Institute. Kim Mi-kyung and So Baek-ho don’t get along and they have conflicts on pretty much everything.
The Potato Lab: A Love Story That Grows Underground
I’ll admit it: I wasn’t expecting much from a show called The Potato Lab. The title alone sounds like a rejected pitch from a corporate brainstorming session—something you’d scroll past on Netflix while searching for the next Crash Landing on You. But here’s the thing about potatoes: they’re humble, unassuming, and, when given the right conditions, they sprout in ways you don’t see coming.
This series does the same.
Set in a rural potato research institute tucked into a mountain valley, The Potato Lab follows Kim Mi-kyung (Lee Sun-bin), a scientist who’s spent 12 years cultivating not just tubers but a life in this quiet corner of the world. Her routine is upended when So Baek-ho (Kang Tae-oh), a corporate restructuring executive, arrives with orders to shut the lab down. What follows is a rom-com that’s equal parts Pride and Prejudice and The Office, with a dash of Napoleon Dynamite’s deadpan absurdity.
It’s a story about clashing worlds—Seoul’s glass towers versus the muddy fields, efficiency versus tradition, and, ultimately, two people who don’t realize they’re both just trying to survive in systems that don’t value what they do.
The first thing that strikes you about The Potato Lab is its tone. It’s loud. Not in the way of a Michael Bay explosion, but in the way of a family dinner where everyone talks over each other, and the dog is barking, and someone’s phone keeps buzzing.
Lee Sun-bin’s Mi-kyung is a whirlwind of physical comedy—pratfalls, exaggerated reactions, and a voice that could cut glass. She’s the kind of character who might annoy you in real life, but on screen, she’s magnetic. There’s a moment in the first episode where Baek-ho, fresh off the bus and already disoriented, gets ambushed by a magpie, tumbles down a hill, and lands in a wheelbarrow.
It’s ridiculous, yes, but it’s also the kind of slapstick that feels earned, not forced. The show isn’t afraid to make its leads look foolish, and that vulnerability is what makes them endearing.
Kang Tae-oh, meanwhile, plays Baek-ho like a man who’s been emotionally neutered by corporate life. He’s the “Tin Man” of the series, a nickname that sticks because he moves through the world with the same stiff precision as his parking-lot ballet (yes, there’s a scene where he directs cars with the grace of a figure skater, and it’s as delightful as it sounds). His performance is all about restraint—tiny shifts in expression, a raised eyebrow here, a flicker of a smile there.
Audience Opinions
Audience 7.2/10
"A quirky blend of comedy and drama with a unique premise, but uneven execution leaves some wanting more depth."
The series stands out for its offbeat concept and the charm of its lead performances, particularly Lee Sun-bin and Kang Tae-oh, who bring energy to the unconventional setting. However, the balance between comedy and drama feels inconsistent, with some episodes struggling to maintain momentum or emotional weight. latestnetflix.com's read is that the supporting cast occasionally fades into the background, leaving the leads to carry the narrative.

Buzz & Rumors
Public reports
The Potato Lab: Off-Screen Heat, On-Screen Potatoes – All the Real-World Tea
latestnetflix.com's take is that the drama might be about healing, romance, and humble spuds, but behind The Potato Lab’s cozy vibes lives a much messier story: low ratings, global obsession, viral dating rumors, and a lead actress whose real boyfriend kept wandering in from another drama entirely.
Scandals & Controversies: The “Flop” That Wouldn’t Die
Ratings humiliation at home, cult hit abroad
In Korea, The Potato Lab quietly crawled along in the 1–2% ratings range, with news reports bluntly calling its numbers a “shocking slump” as episodes dipped to 1.4–1.8% nationwide . Viewers on Korean Facebook groups called it “disappointing” and “probably my least favorite of all the K‑Dramas I’ve watched” . But then came the twist even K‑drama writers would call “too on the nose”: allkpop reported that the show was seeing “remarkable global success on Netflix despite its low popularity in Korea” . Domestic flop, international girlie.
“Crass” humor and character assassination?
A widely shared Substack review dragged the series for “crass humour and lack of character development,” arguing it “didn’t deliver the rom-com we were expecting” . International fans on Facebook piled on, slamming the female lead’s behavior and saying they only stuck with the show “because of Kang Tae-oh” . No lawsuits, no boycotts—just the modern career hazard: getting ratioed by drama fans.
Romance Rumors: A Love Triangle With Reality Itself
The fake ship everyone wanted… that could never sail
YTYouTube·Kang Tae Oh And Lee Sun Bin (The Potato Lab) Rea…
From the moment Kang Tae-oh and Lee Sun-bin were announced as leads, Korean outlets were already nudging the rumor mill. One Daum article basically winked at the audience with the headline, “Kang Tae-oh ♥ Lee Sun-bin, will dating rumors explode?” while praising their “exciting playful chemistry” on The Potato Lab. TikTok edits, YouTube videos, and fan comments kept asking the same thing: “Are they dating in real life?” Many fan-made “real-life partners” videos tried to stitch together clues from press cuts and behind-the-scenes footage .
Reality check: Sun-bin’s very real, very public boyfriend
The catch? Lee Sun-bin has been publicly dating Running Man star Lee Kwang-soo for years. In March 2025, during The Potato Lab promotion cycle, an English-language Chosun Biz piece highlighted that she has been in an eight-year relationship with Lee Kwang-soo and described her romantic style as “all-in, straight-forward” . Around the same time, Facebook fan pages shared clips gleefully titled “Lee Sun-bin Jokes About Boyfriend Lee Kwang-soo at ‘The Potato Lab’ Press Conference!” where she referenced him while sitting beside Kang Tae-oh . So while fans continued to ship “SunBin x TaeOh,” the only confirmed love line was still “SunBin x Kwang-soo.”
Breakup rumors… immediately killed
As the drama aired and the on-screen chemistry soared, some fans speculated online about a possible Sun-bin/Kwang-soo breakup. That fantasy didn’t last: in late 2025, Lee Kwang-soo went on SBS and flat-out said there was “no breakup” and that he and Lee Sun-bin “won’t break up,” addressing marriage rumors and confirming they were still going strong after eight years .
On-Set & Press-Conference Tea
The earpiece incident that became meme material
YTYouTube·Instead of saying something, Kang Tae Oh was jus…
At the drama’s press conference, Kang Tae-oh had a moment that fans turned into a running joke. In a YouTube video covering the event, he’s seen repeatedly adjusting his earpiece instead of answering questions, leaving the mood adorably awkward and giving stan Twitter and TikTok enough reaction material for weeks . No screaming fights, no walkouts—just a shy lead and a malfunctioning monitor feeding the meme machine.
“Healing rom-com” vs. “crass comedy”
While tvN and international promo reels sold The Potato Lab as a “healing romantic comedy” set in a rural lab, online discussions (especially Reddit and Facebook) split into two camps:
Those who praised the chemistry and “laugh-out-loud” moments
Those who felt the humor was too loud, too crude, and undermined the romance, calling it “not the rom-com we were promised”
The tonal whiplash became its own kind of gossip—was it a healing rom-com, or a chaotic B‑grade screwball experiment?
Wild Trivia & Behind-the-Scenes Nuggets
Kang Tae-oh’s big comeback vehicle
The Potato Lab was Kang Tae-oh’s first role after completing his mandatory military service in March 2024. Korean and international outlets explicitly framed the show as his “comeback project,” noting this was his first drama post-discharge . That made the lukewarm domestic response a hot topic among fans who’d waited 18 months for his return.
Real farmers, real fields, real potatoes
IGInstagram·The Potato Lab (2025) — This romantic comedy sta…
Promotional content on Instagram revealed that the production team actually worked with agricultural experts and filmed in real mountain valley locations to make the Potato Research Institute feel authentic . For a rom-com about potatoes, the commitment to agronomy was oddly hardcore.
From “generic” to “symbolic”?
Not all commentary was just about ratings. An allkpop feature on evolving K-drama storytelling noted how The Potato Lab turns its rural research center into a kind of microcosm of Korea’s urban–rural divide, drawing unexpected praise from critics who saw more under the surface than just spud jokes . Fans seized on that angle in discussions, spinning theories about capitalism, aging, and burnout—proof that even a “failed” romance about potatoes can spark think pieces.
Fandom Fallout & Legacy
Love it, hate it, can’t stop talking about it
On r/KDRAMA and multiple Facebook groups, The Potato Lab became a “should I watch this?” lightning rod. Some called it a light, fun rom-com worth your time ; others suggested it was only bearable because of Kang Tae-oh, citing frustration with the female lead’s behavior . That messy split between domestic viewers, international fans, and critics gave The Potato Lab what every show secretly wants: a long tail of discourse, edits, and arguments that kept its name alive long after the finale.
No arrests. No Dispatch cheating scandals. Just a ratings underdog with global clout, weapon-grade chemistry between co-stars who are definitely not dating, and a lead actress whose real-life boyfriend kept showing up—in headlines, if not in the lab.
