The trailer for the 12th Jecheon International Music & Film Festival captures the image of a child who accidentally discovers the beauty and joy of music. The guitar performance by film music director Mog and the intense rhythm of percussion instruments blend perfectly in this trailer, which showcases the emotional direction of director Lim Pil-seong. Young actress Kim Ha-na, who had no prior acting experience but gave an outstanding performance in the film *Detective Hong Gil-dong: The Vanished Village*, also beautifully portrays the moment of falling into the beauty of music and dance with her unique emotional expression in this trailer.
