  "lyrics": "[intro]\n(Chords: C#m - A - E - B)\n(Inst: Ethereal piano arpeggios, gentle synth pad swell.)\n(Vocal-Perf: Breathy female vocalise, high register, floating melody.)\n(Mix: Intimate, narrow stereo field, heavy reverb on vocalise.)\n\n[chorus]\n(Chords: C#m - A - E - B)\n(Vocal-Perf: Male tenor, clear and centered, mezzo-forte, sustained notes.)\n(Inst: Full band enters. Driving half-time drum beat with fast hi-hats. Soaring string section. 808 bass anchors the harmony.)\n(Mix: Wide stereo image, vocals upfront. Strings and pads fill the space.)\n(Melody-Contour: Ascending line, builds tension, resolves on the tonic.)\n让爱成为你我心中 那永远盛开的花\n穿越时空绝不低头 永不放弃的梦\n\n[verse]\n(Transition: Strings fade out, leaving piano and rhythm.)\n(Chords: C#m - A - E - B)\n(Vocal-Perf: Female vocal enters, breathy and soft, conversational rhythm. Then transitions to smooth male R&B vocal, slightly more on-the-beat.)\n(Inst: Instrumentation thins out. Piano becomes the main focus with the kick and hi-hats keeping time.)\n(Mix: Vocals feel closer, more intimate.)\n우리 너무 사랑해서 아팠었네요\n서로 사랑한단 말도 못했었네요\nOh baby I just want a love that will go endless forever\nThrough the dreams that we found we won’t give up never\n\n[pre-chorus]\n(Transition: Cymbal swell and subtle filter sweep.)\n(Chords: A - E - B - C#m)\n(Vocal-Perf: English male vocal, builds in intensity, slight melodic lift at the end of phrases.)\n(Inst: Drums become slightly busier, adding a quiet snare fill. Synth pad volume increases.)\n(Structure: Energy builds towards the chorus.)\nI,I can see you from my past life\nI,I see a star in the dark night\nEverybody has their own journey\nBut everything about you feels right\n\n[chorus]\n(Transition: Clean impact as full instrumentation returns.)\n(Chords: C#m - A - E - B)\n(Vocal-Perf: Male tenor, powerful and emotive, ad-libs from other vocalists in the background.)\n(Inst: Strings re-enter with a more dramatic, sweeping line. Piano plays block chords for emphasis.)\n(Mix: Expansive and full, maximum dynamic energy.)\n(Highlight: The blend of Mandarin lead with subtle English/Korean ad-libs showcases the multilingual theme.)\n让爱成为你我心中 那永远盛开的花\n穿越时空绝不低头 永不放弃的梦\n\n[bridge]\n(Transition: Abrupt cut of drums, leaving reverberant piano chord.)\n(Chords: A - E - B - C#m - A - E - F#m - G#)\n(Vocal-Perf: English R&B vocal, starts soft and vulnerable, grows in desperation and power.)\n(Inst: Starts with just piano and vocal. Drums re-enter with a slow, powerful build using tom-toms and cymbal swells.)\n(Mix: Dynamic shift from sparse to dense, creating an emotional arc.)\nMemories in the shadows\nIn a world so cold\nIt’s my heart I got to follow\nI can’t lose control\nI got a broken heart and it’s torn in two\nbut there is not a moment I would undue\nI tell myself to let it go\n\n[outro]\n(Transition: Music fades slowly over several bars.)\n(Chords: C#m - A - E - B)\n(Inst: Piano arpeggios return, echoing the intro. A single sustained string note holds.)\n(Vocal-Perf: Faint, distant ad-libs from all three vocalists, weaving together.)\n(Mix: Long reverb tails, slow fade to silence.)",
