  "lyrics": "[intro]\n(Chords: B - F# - C# - D#m)\n(Inst: Main arpeggiated plucky synth hook enters immediately. Punchy electronic beat with 16th-note hats joins after 2 bars. Deep sub-bass.)\n(Mix: Wide stereo synths, centered beat.)\n(Sound-Design: Filtered vocal chop sample \"I'm thinking about you\" with heavy delay.)\n\n[verse]\n(Chords: B - F# - C# - D#m)\n(Vocal-Perf: Light, breathy, conversational delivery. Very clear enunciation. Lower in the register.)\n(Inst: Beat continues, but pads are softer. Sub-bass holds root notes. Lead synth is absent.)\n(Mix: Vocals upfront and centered with noticeable reverb. Instruments create a spacious bed.)\n弥漫的烟\n散不出留在房间\n我在窗前\n捧着书本和茶点\n我总是失望对于自己和明天\n灯光下的微点\n又晃了我的眼\n\n[pre-chorus]\n(Chords: B - F# - C# - D#m)\n(Transition: Filtered synth riser builds into pre-chorus.)\n(Vocal-Perf: Intensity builds slightly. More sustained notes. Layered backing vocals enter.)\n(Inst: Snare becomes more prominent. A new pad layer adds harmony. Sidechain pumping on pads is more audible.)\n耳机播放着鼓点\n保持我们初见时的新鲜\n找个舒适的距间\n可我的性拾总让我感觉亏欠\n\n[chorus]\n(Chords: B - F# - C# - D#m)\n(Transition: Snare roll and riser FX.)\n(Vocal-Perf: Stronger chest voice. More open and melodic. Backing vocals create a full texture.)\n(Inst: All elements are present. The main plucky synth hook returns, playing counter-melodies around the vocal.)\n(Melody-Contour: Ascending melody line, memorable peak note on key words.)\n不确定的地点和一个待定的时间\n我怎么也会走进一场未知的沦陷\n一想到你就没有任何不适的感觉\n未来的每一天\n都多爱你一遍\n\n[verse]\n(Chords: B - F# - C# - D#m)\n(Transition: Brief instrumental hook phrase leads into the verse. Energy drops.)\n(Vocal-Perf: Returns to light, conversational style. Subtle variations in phrasing from first verse.)\n(Inst: Arrangement thins out again, similar to first verse.)\n弥漫的烟\n散不出留在房间\n我在窗前\n捧着书本和茶点\n我总是失望对于自己和明天\n灯光下的微点\n又晃了我的眼\n\n[pre-chorus]\n(Chords: B - F# - C# - D#m)\n(Transition: Riser FX builds energy again.)\n(Vocal-Perf: Intensity builds, matching the first pre-chorus.)\n(Inst: Drums and pads re-enter with full energy.)\n耳机播放着鼓点\n保持我们初见时的新鲜\n找个舒适的距间\n可我的性拾总让我感觉亏欠\n\n[chorus]\n(Chords: B - F# - C# - D#m)\n(Vocal-Perf: Full power, most emotional delivery of the song. Possible ad-libs in background.)\n(Inst: Full instrumental arrangement. High energy.)\n(Mix: Widest and fullest section of the song.)\n不确定的地点和一个待定的时间\n我怎么也会走进一场未知的沦陷\n一想到你就没有任何不适的感觉\n未来的每一天\n都多爱你一遍\n\n[outro]\n(Chords: B - F# - C# - D#m)\n(Transition: Beat drops out, leaving pads and vocal echo to fade.)\n(Inst: Beat fades out, leaving the plucky synth hook and warm pads.)\n(Sound-Design: The \"I'm thinking about you\" sample repeats with increasing delay and reverb, fading into silence.)\n(Mix: Elements fade out one by one, ending on a sustained synth pad with a long reverb tail.)",
