A mid-tempo Japanese pop track in E♭ major at 125 BPM, 4/4 time, blending alternative pop and urban ballad sensibilities, The arrangement is built on a steady 4-on-the-floor kick with a crisp snare on beats 2 and 4, and hi-hats shifting between 8th and 16th note patterns, Clean electric guitars provide rhythmic chord stabs and light arpeggios, while piano comping adds harmonic texture, Soft synth pads fill the background, and occasional lead lines from guitar or synth add melodic accents, Verses are kept minimal and intimate, focusing on vocals with restrained rhythm, while pre-choruses introduce syncopated snare hits and harmonic lift, The choruses open up with sustained chords, open hi-hats, and a wider stereo image, creating a sense of release, Harmony centers on E♭ major, enriched by modal mixture and non-diatonic passing chords such as E♭ – D – Gm, with smooth bass motion via slash chords and occasional diminished chords for tension, The structure follows intro → verse → pre-choru
