The song's second half features a more dynamic and rhythmic brass arrangement along with a prominently featured nostalgic tone. Pre-release single "Phantom Pain" is the second track of the album. Classified as an indie pop song, the track features a soft electric guitar and rhythmic drum sound in the background with its lyrics likening a breakup into a medical condition of the same name as the track. "Corazón Perdido (Lost Heart)" is a dream pop song fused with rock flavor featuring a lyrical acoustic guitar and a heavy bass in the background before the song became more energetic due to Yesung's vocals.
