 The title song is described by CDJapan as "a ballad perfect for the love story in the film", and came with a special, limited letter from Hitomi.The coupling track on the single, "DRIVE", was labeled as "special", because of the many different other artists who worked on the song.Such people include SHOGO (175R) arranging the music, TAKUYA producing the music, TEPPEI (from 3.6MILK) on the guitars, SATOSHI (from 3.6MILK) on the bass guitar, and MOBY (from SCOOBIE DOO) on the drums.
