The album's first single, "Twins (Knock Out)" is a rap rock release. Featuring eagle-like dancing, the dance choreography arranged for the song became warmly welcomed and extremely popular. The follow-up single, "Miracle", is a typical K-pop bubblegum pop song, a genre still very welcomed by children and young adults. Like the song itself, the dance choreography for the single is also simpler and softer. The rest of the tracks in their first studio album mainly consist of pop love ballads and also R&B-influenced dance tracks with rap and fast drum beats.
