A sanjo gayageum with 12 strings and a harp with forty-seven strings. Gayageum player Joo Bo Ra and harpist Lee Ki Hwa form a duo named Il Sa Chil to arrange a meeting of two traditional string instruments linking East and West. The two people who are preparing for their first performance through the era of Corona 19 are getting closer to each other as they learn the differences between each other’sinstruments. Their music, who undergoes emptiness through learning and interprets this as artistic giving, sits down and takes root in the stage, the sea, the street and the living room. The voice of actress Jeong Ae Ri, who is the narrator, calmly harmonizes with the melody of the string instrument.
