"Polar Star" was classified as a medium-tempo rock song that describes a love that never changes, similar to how the location of a pole star never changes. "Fallin' for You" is an acoustic rock song that "depicts a man who isn't able to get close to the woman he loves". Lee was inspired to write the melody from playing his acoustic guitar. "Beautiful World" is a rock ballad that incorporates the use of a piano, which was described as having a sound not previously heard from F.T. Island. Choi composed the melody while thinking of the lyrics, which describe how "a man looks on at his lovely lover".
