  "lyrics": "[intro]\n(Chords: Eb - Bb/D - Cm - Ab)\n(Mix: Wide stereo field; Strings and bell synth prominent)\n(Inst: Dreamy bell-like synth ostinato enters, joined by a lush orchestral string swell, establishing the romantic theme.)\n(Sound-Design: Gentle tape hiss for warmth.)\n\n[verse]\n(Chords: Eb - Bb/D - Cm - Ab)\n(Vocal-Perf: Conversational, breathy, mezzo-piano delivery)\n(Inst: Strummed acoustic guitar and simple root-note bass enter, drums play a light backbeat on the rim.)\n(Mix: Vocals centered and upfront, intimate feel.)\n(Transition: Hi-hat opens up slightly at the end.)\n窗外的麻雀在电线杆上多嘴\n你说这一句很有夏天的感觉\n手中的铅笔在纸上来来回回\n我用几行字形容你是我的谁\n\n[pre-chorus]\n(Chords: Fm - Gm - Ab - Bb)\n(Vocal-Perf: Volume increases slightly, more melodic and less conversational)\n(Inst: Strings re-enter with a sustained pad, building tension. Drummer moves to full snare.)\n(Melody-Contour: Ascending line to build anticipation for the chorus.)\n(Transition: Subtle cymbal swell.)\n秋刀鱼的滋味猫跟你都想了解\n初恋的香味就这样被我们寻回\n那温暖的阳光像刚摘的鲜艳草莓\n你说你舍不得吃掉这一种感觉\n\n[chorus]\n(Chords: Eb - Bb/D - Cm - Gm - Ab - Eb/G - Fm - Bb)\n(Vocal-Perf: Mezzo-forte, smooth, sustained phrasing, clear tone)\n(Inst: Full band enters. Soaring, cinematic string melody becomes the main counterpoint to the vocal. Drums are solid and driving.)\n(Mix: Expands to full width, strings panned wide, creating a lush, immersive soundscape.)\n(Highlight: The orchestral strings create a cinematic, romantic layer over the pop-rock groove.)\n雨下整夜我的爱溢出就像雨水\n院子落叶跟我的思念厚厚一叠\n几句是非也无法将我的热情冷却\n你出现在我诗的每一页\n\n[bridge]\n(Chords: Ab - Bb - Gm - Cm - Fm - Bb - Eb)\n(Vocal-Perf: Returns to a more intimate and reflective tone, then builds back up)\n(Inst: Dynamics drop. Clean electric guitar plays gentle arpeggios. Bass becomes more melodic.)\n(Mix: Narrows slightly to refocus on the vocal narrative.)\n(Transition: Drum fill leads powerfully into the final chorus.)\n那饱满的稻穗幸福了这个季节\n而你的脸颊像田里熟透的番茄\n你突然对我说七里香的名字很美\n我此刻却只想亲吻你倔强的嘴\n\n[chorus]\n(Chords: Eb - Bb/D - Cm - Gm - Ab - Eb/G - Fm - Bb)\n(Vocal-Perf: Forte, most passionate and powerful delivery of the song)\n(Inst: All instruments playing at full intensity. Cymbals are more prominent. Strings are at their most epic and layered.)\n(Mix: Widest point of the mix, maximum energy and emotional impact.)\n雨下整夜我的爱溢出就像雨水\n窗台蝴蝶像诗里纷飞的美丽章节\n我接着写\n把永远爱你写进诗的结尾\n你是我唯一想要的了解\n\n[outro]\n(Chords: Eb - Bb/D - Cm - Ab)\n(Inst: Music fades out with the bell synth ostinato, strummed acoustic guitar, and the final sustained notes from the string section.)\n(Mix: Gradual fade to silence, leaving the listener with the lingering romantic melody.)\n(Sound-Design: The bell motif echoes softly as it fades.)",
