Hometown Cha-Cha-Cha Season 1 A big-city dentist opens up a practice in a close-knit seaside village, home to a charming jack-of-all-trades who is her polar opposite in every way.
Yoon Hye-Jin (Shin Min-A) works as a dentist. She is mostly a realist, but due to her rightfulness, which is only a tiny part of her mind, her life changes. She ends up moving to the seaside village of Gongjin. There, Yoon Hye-Jin meets Hong Du-Sik (Kim Sun-Ho).
She becomes curious about him. Hong Du-Sik is called Chief Hong by the local residents. He is a handsome and smart man. Officially, he is unemployed, but he always seems busy. If somebody needs help, Hong Du-Sik is the first one to appear and provide help.
