Hometown Cha-Cha-Cha (Review) is indeed the popular 2021 South Korean romantic comedy-drama that fits the description. It centers on Yoon Hye-jin, a pragmatic and successful dentist from Seoul, who experiences a career setback and impulsively decides to move to the charming seaside village of Gongjin. There, she encounters Hong Du-sik, known to the villagers as "Chief Hong," an officially unemployed but incredibly capable jack-of-all-trades who helps everyone with any task, big or small.
