The seaside village of Gongjin has exactly one dentist, and she did not plan to stay. Yoon Hye-jin arrives from Seoul on her late mother’s birthday, her city life in pieces, and opens a practice on impulse. That decision sets up Hometown Cha-Cha-Cha, tvN’s 2021 romantic comedy, and it is the rare show that knows a small town is not a backdrop but a machine with a hundred moving parts.

A Dentist From Seoul Lands in Gongjin
Hometown Cha-Cha-Cha stars Shin Min-a as Hye-jin and Kim Seon-ho as Hong Du-sik, the jack-of-all-trades the village calls Chief Hong. He is her polar opposite in every way, and the show leans on that contrast without apology.
Lee Sang-yi plays Ji Sung-hyun, a variety show director who circles the same orbit. The rest of the cast fills out Gongjin: Gong Min-jeung plays Pyo Mi-seon, and Kim Yeong-ok plays Kim Gam-ri. Cho Han-chul takes the role of Oh Chae-jun, while In Gyo-jin appears as Chang Yeong-guk. Lee Bong-ryeon is Yeo Hwa-jeong, Cha Chung-hwa is Jo Nam-sook, and Kang Hyung-suk plays Choi Eun-cheol. Lee Suk-hyeong appears as Kang Do-ha, with Lee Yong-yi as Lee Mat-i.
The series is a remake of the 2004 South Korean film Mr. Handy, Mr. Hong. Yu Je-won created it with Shin Ha-eun, and Yu’s history with Shin Min-a goes back to Tomorrow with You in 2017.
It ran for one season and 16 episodes on tvN, from August 28 to October 17, 2021, in the Saturday and Sunday 21:00 KST slot. Netflix carries it for streaming.
Chief Hong and the Case for the Slow Build
Here is the thing about the premise: it is not a premise. A big-city dentist relocating to a close-knit village is the setup for a hundred dramas, and most of them treat the village as wallpaper behind a single love story.
Hometown Cha-Cha-Cha does not. The romance between Hye-jin and Du-sik grows alongside the lives of the other residents of Gongjin, and the show gives those residents real weight. The synopsis promises a charming jack-of-all-trades who is her polar opposite in every way, and Kim Seon-ho delivers exactly that — a man who can fix a boat, a fuse and a neighbor’s mood, and who resists being known.
Shin Min-a’s Hye-jin is the harder role. She has to be competent and adrift at once, a woman who moved because her life went awry rather than because she wanted a sea view. The show does not make her a fish out of water for laughs. It makes her a professional in a place that has its own rules about what help looks like.
It is a remake of the 2004 South Korean film Mr. Handy, Mr. Hong.
That lineage matters more than it sounds. Remakes usually inherit plot and lose texture. This one keeps the bones and builds the village around them, which is why 16 episodes feel like a stay rather than a sprint.
The Ratings Told a Bigger Story
The numbers here are not trivia. Hometown Cha-Cha-Cha became one of the highest-rated dramas in Korean cable television history. It ranked first place in its timeslot for its entire run, and the last episode hit a 12.665% nationwide rating.
It also became one of Netflix’s most-watched non-English television shows. That combination — domestic cable dominance plus global streaming reach — is the part of this story that actually matters.
Consider what the show was working with:
- A remake of a 2004 film, which invites comparison before a single frame airs
- A 16-episode run on tvN, Saturdays and Sundays at 21:00 KST
- Two leads confirmed on April 2, 2021, after offers reported on December 21, 2020
- A director reuniting with his star for the first time since 2017
- Netflix releasing script-reading photos on June 23, 2021, months before broadcast
None of that guarantees an audience. Casting announcements began December 21, 2020, when Kim Seon-ho and Shin Min-a were reported to have been offered the lead roles. Lee Sang-yi was also reported to have been offered a role. By April 2, 2021, Kim and Shin were officially confirmed as the leads.
The show had a long runway and used it. Netflix put out script-reading photos on June 23, 2021, which is a small thing that signals a big one: the platform was treating this as a title worth promoting, not a catalog filler.
What the Show Gets Right, and What It Skips
The strongest argument for Hometown Cha-Cha-Cha is that it refuses to make Gongjin quaint. A close-knit seaside village in lesser hands becomes a collection of quirks. Here it becomes a place with an economy, a hierarchy and a memory.
The comedy and drama tags are accurate, but the balance tilts toward drama in the back half. That is a choice, and it mostly works, because the show has spent its early episodes earning the right to slow down.
The weak point is the same one that dogs most romances built on opposites: the opposition has to stay interesting. Chief Hong’s charm is that he is capable and evasive, and Hye-jin’s is that she is accomplished and unmoored. Once both are explained, the engine loses a gear. The show knows this, which is why it keeps handing scenes to the supporting cast.
Kim Yeong-ok as Kim Gam-ri, Cha Chung-hwa as Jo Nam-sook, Lee Bong-ryeon as Yeo Hwa-jeong — these are not decoration. They are the reason the village holds together when the central couple stalls.
The Verdict on Hometown Cha-Cha-Cha
This is a show that understood its assignment better than most. It took a 2004 film premise, cast two leads who could carry it, and then did the harder work of building a town instead of a set.
The 12.665% nationwide rating for the finale and the first-place timeslot streak are not accidents. They are what happens when a drama gives viewers a place they want to return to every Saturday and Sunday at 21:00 KST.
The Netflix reach matters too. One of the platform’s most-watched non-English television shows is a real achievement, and it says something about how far a Korean cable romantic comedy can travel when the writing holds.
What holds it back from a higher mark is the middle stretch. Sixteen episodes is a long time to sustain a will-they-won’t-they when the audience already knows the answer, and the show occasionally pads rather than deepens. The supporting cast covers for it, but the seams show.
Still, the seams are minor. Hometown Cha-Cha-Cha is warm without being soft, and it treats its village as a place where people have jobs, debts and histories. That is rarer than it should be.
Shin Min-a and Kim Seon-ho are the reason to start it. The residents of Gongjin are the reason to finish it. And the ratings record is the reason tvN will keep making shows like this.
