One winter, Yu Jun Sang and Lee Jun Hwa, the two members of a band “J and Joy 20” get on a flight to Japan with an impulse to film a music video. They set off to Japan, without any actors or themes prepared and armed only with an ambitious plan to make a song for spring. As Japanese musical actor Nakagawa Akinori and two Korean actors Kim So Jin and Jung Soon Won gather together, a joyful production of the music video unfolds on a snowfield with Mount Fuji in the background. Spring Song is a record of passionate creations and a pleasant aria about artists with simple and pure minds.
