  "prompt": "Genre: Acoustic Folk-Pop Ballad; BPM: 143; Key: C# Major; Rhythm: Sparse, half-time ballad groove (kick on 1, snare on 3) with a gentle, fingerpicked acoustic guitar providing sixteenth-note momentum.; Instruments: Close-mic'd acoustic guitar, finger squeaks audible; Clean electric guitar, glassy ambient lead; Simple drum machine, soft kick & clap; Unobtrusive electric bass, clean tone.; Vocals: Multiple Male Vocals, ranging from intimate close-mic tenor to strained emotional falsetto, with a raw, breathy delivery.; Mood: The quiet hum of a refrigerator at 3 AM, scrolling through old photos on a phone you know you shouldn't be looking at.; Highlight: The first long, sustained note of the electric guitar solo in the bridge, hanging over the sparse chords with a touch of vibrato, wordlessly crying out the song's central regret.",
  "lyrics": "[verse]\n(Mix: Intimate, centered mix. Vocals dry and upfront with light plate reverb. Wide stereo acoustic guitar. Warm low-mids, controlled highs. Minimal bus compression, preserving dynamics.)\n(Inst: Close-mic'd steel-string acoustic, fingerpicked arpeggios, fret noise audible.)\n(Vocal-Perf: Breathy, gentle male tenor, vulnerable and close to the mic.)\n(Chords: C# - G# - A#m - F#)\n그녀가 떠나가요\n나는 아무것도 할 수 없어요\n사랑이 떠나가요\n나는 바보처럼 멍하니 서있네요\n멀어지는 그 뒷모습만을 바라보다\n작은 점이 되어 사라진다\n시간이 지나면 또 무뎌질까\n옛 생각이 나\n니 생각이 나\n\n[chorus]\n(Mix: Drum machine enters, adding weight to the center. Vocal harmonies subtly widen the stereo field.)\n(Inst: Acoustic guitar shifts to light strumming. Soft drum machine (kick on 1, clap on 3). Subtle bass root notes.)\n(Vocal-Perf: Intensity increases to an emotional, strained chest voice. Backing harmonies enter.)\n(Chords: F# - C# - G# - A#m)\n(Hook-DNA: Core motif is two quarter notes on the title phrase, landing on beat 1 & 2, followed by a rest; anchors on the 5th and 3rd; repeats twice before a longer concluding phrase.)\n(Melody-Contour: Ascending arch, peaks with a leap of a major 3rd, resolves downwards.)\n(Melody-Rhythm: Phrases start directly on beat 1, deliberate and on the grid.)\n(Melody-Harmonic-Tension: Melody holds the 3rd over the IV chord creating a stable, yearning feel, before a stepwise descent to the root over the I chord.)\nIf you\nIf you\n아직 너무 늦지 않았다면\n우리 다시 돌아갈 수는 없을까\nIf you\nIf you\n너도 나와 같이 힘들다면\n우리 조금 쉽게 갈 수는 없을까\n있을 때 잘할 걸 그랬어\n\n[verse]\n(Inst: Drum machine continues its sparse pattern. Acoustic guitar returns to arpeggios.)\n(Vocal-Perf: A second male vocalist takes the lead, timbre is slightly fuller but maintains the strained, emotional delivery.)\n(Chords: C# - G# - A#m - F#)\n그대는 어떤가요\n정말 아무렇지 않은 건가요\n이별이 지나봐요\n그댈 잊어야 하지만 쉽지가 않네요\n멀어지는 그 뒷모습만을 바라보다\n작은 점이 되어 사라진다\n누군갈 만나면 위로가 될까\n옛 생각이 나\n니 생각이 나\n\n[chorus]\n(Mix: Vocal harmonies are more prominent and wider in the mix. Overall level lifts slightly.)\n(Inst: Drum beat becomes slightly more active with a ghost-note hi-hat.)\n(Vocal-Perf: Lead vocal is more powerful, with emotional ad-libs layered in the background.)\n(Chords: F# - C# - G# - A#m)\n(Hook-DNA: Core motif is two quarter notes on the title phrase, landing on beat 1 & 2, followed by a rest; anchors on the 5th and 3rd; repeats twice before a longer concluding phrase.)\n(Melody-Harmonic-Tension: Increased vocal power heightens the tension on the IV chord before the resolution on the tonic feels more cathartic.)\nIf you\nIf you\n아직 너무 늦지 않았다면\n우리 다시 돌아갈 수는 없을까\nIf you\nIf you\n너도 나와 같이 힘들다면\n우리 조금 쉽게 갈 수는 없을까\n있을 때 잘할 걸 그랬어\n\n[bridge]\n(Mix: Instruments pull back, creating an open space for the electric guitar solo. Reverb on the guitar is more pronounced.)\n(Inst: Acoustic guitar holds down-strummed chords. Drums simplify. Clean electric guitar enters with a lyrical, melodic solo.)\n(Vocal-Perf: Delivery shifts to a half-spoken, reflective tone before dropping out for the guitar solo.)\n(Chords: F# - C# - G# - A#m)\n(Melody-Harmonic-Tension: The electric guitar solo creates tension by holding long, bent notes (e.g., the ♭7) over major chords, delaying resolution and mimicking a pained vocal line.)\n오늘같이 가녀린 비가 내리는 날이면\n너의 그림자가 떠오르고\n서랍 속에 몰래 넣어둔 우리의 추억을\n다시 꺼내 홀로 회상하고\n헤어짐이란 슬픔의 무게를\n난 왜 몰랐을까\n\n[outro]\n(Inst: All instruments become sparse, fading out on a final, sustained acoustic chord.)\n(Vocal-Perf: Final sung phrase is delivered with a sense of quiet resignation, almost a sigh.)\n(Sound-Design: Final reverb tail of the acoustic guitar fades slowly into silence.)\n있을 때 잘할 걸 그랬어",
