[12] It also became one of Netflix's most-watched non-English television shows, and one of its longest-running hits as it spent 16 weeks in global top ten rankings.

[13][14] Yoon Hye-jin, an accomplished dentist from Seoul, goes to the idyllic seaside village of Gongjin on her late mother's birthday after her life goes awry.

Feeling upset, she confides in her best friend Pyo Mi-seon over the phone, unaware that the microphone in the room is switched on, causing the entire village to overhear their conversation.

Upon learning about the situation, Pyo Mi-seon advises Hye-jin to consider leaving Gongjin due to the negative impression she has made.

While Du-sik is absent, Hye-jin, longing for his presence, attends a prosperity meeting for Gongjin shop owners in the hope of encountering him.

However, the crowded gathering and overwhelming atmosphere make it difficult for her to feel included, prompting her to pretend to be drunk to avoid conversation.

Their blossoming romance fills Hye-jin with excitement, prompting her to compile a detailed bucket list of activities she dreams of experiencing with Du-sik, including a memorable date in Seoul.

Meanwhile, a typhoon wreaks havoc, blocking all roads and forcing Ham Yun-gyeong to give birth at Hye-jin's home, adding unexpected excitement to the situation.

[44] On April 2, 2021, it was officially announced that Yoo Je-won will be directing the drama literally translated as Seaside Village Cha-Cha-Cha (갯마을 차차차).

It required a significant amount of time due to the involvement of a large number of people and the unpredictable weather during the rainy season.

The choreography for the song was created by Jo Young-seo and Kim Do-gyun, who are choreographers and dancers from a group called Dance of Soul (DOS).

[61] The Hometown Cha-Cha-Cha soundtrack album, written by music director Lim Ha-young, comprises 11 songs (including singles) and 32 score pieces from the series.

The album features vocal performances from artists such as Car, the Garden, Kassy, Cheeze, Choi Yu-ree, Kim Jae-hwan, Sandeul, Seungmin (Stray Kids), and Lee Sang-yi.

In addition to the 8 previously released OST songs, the album includes "Just a Feeling" by the fictional idol group 'DOS' in the drama, which was highly requested by viewers.

It also features two songs by "Oh Yoon," performed by actor Jo Han-chul as the superstar of 'Gongjin' in the drama, titled "Exercise at the Moonlit Night" and "End and Beginning."

The wine that Yoon Hye-jin gifted to Hong Du-sik in episode 5 received a sudden influx of orders and temporarily sold out.

[99] Kim Haeng-sook's poetry book, "Portrait of Echo," garnered renewed attention after one of its poems, "The Gatekeeper," was featured in the drama.

[100] Additionally, the Korean translation of Henry David Thoreau's Walden, which Hong Ban-jang read in episode 2 of the drama,[101] reached the 11th spot on Yes24's bestseller list in the essay category by the second week of October.

[105] Jan Lee of The Straits Times gave the drama a rating of 4/5 stars, pointing out three reasons to tune in to Hometown Cha-Cha-Cha were idyllic setting, charming leads and colourful supporting characters.

[106] Pierce Conran from South China Morning Post gave the drama a rating of 3.5/5 stars and said that the hit romcom kept things simple and though it occasionally indulged in some hokey dramatics to strengthen its wafer-thin narrative, it was never in danger of alienating its committed audience, which was hooked to the last.

[107] S. Poorvaja from The Hindu said, "Ultimately, Hometown Cha-Cha-Cha is a good example of how K-dramas can get romance right, even as it attempts to provide more nuance and depth into the struggles of its lead characters.

For everyone who has had their minds blown by Squid Game, this outing is a worthy representation of what else K-dramas excel at: slice-of-life goodness and wholesome romance of the best kind.

"[110] Joel Keller of Decider gave a mixed review, stating, "There's enough good things about Hometown Cha-Cha-Cha, including the seashore scenery and the chemistry between the show's leads, to recommend it.

Bang pointed out some disappointing aspects, stating, "The portrayal of men and women in the drama followed typical stereotypes, despite attempting to showcase the contrasting personalities of Du-sik and Hye-jin in three dimensions.

This was attributed to the development of not only the romantic relationships in Gongjin, a seaside town, but also the endearing and affectionate characters of the townsfolk, which created a calming and enjoyable atmosphere.

[114] Columnist Jung Deok-hyeon from Entermedia also expressed a similar sentiment, particularly regarding a scene involving a house trespasser that seemed to appear out of nowhere to further the relationship between Yoon Hye-jin and Hong Du-sik.

Jung Deok-hyeon mentioned that this particular aspect of the drama felt like a weakness, as clichés that may have been more acceptable in the past are now harder to embrace due to changing sensibilities.

Despite these perceived weaknesses, the viewer response was not bad, mainly because the fantasy depicted through the virtual setting of Gongjin in this drama was exceptionally compelling.

[118] According to Yangju's official, the museum caught the attention of viewers with its distinct white structure and its harmonious integration with the surrounding natural environment.
