"Farewell Song" is an original work by Shinjou-P featuring KAITO. It is a light-paced song with strong harmonies of piano and violin. The lyrics can be interpreted as a farewell song to a lost lover and the yearning for those days of love. The "na 4M" line in the lyrics comes from Vocaloid phonetics.
