A light drum fill leads into the verse.)\n(Mix: Centered guitar, intimate space.)\n\n[verse]\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Conversational, mezzo-piano, clear chest voice.)\n(Inst: Programmed drums enter with a steady kick/snare backbeat and constant 16th-note hi-hats. A round sub-bass plays root notes. Clean guitar continues arpeggiating.)\n体育馆门口的自行车棚\n你的那辆红色的链条总是松\n每次下课你都要蹲下来调\n我就靠着墙壁数你拨链条的声\n那本借了三个月没还的参考书\n扉页上你随手画了只丑烂虫\n我翻到那页就不自觉想笑\n现在那本书还塞在我行李箱中\n\n[pre-chorus]\n(Chords: D - E - F#m - E)\n(Vocal-Perf: Open, wordless \"woah\" vocals in layered harmony, building intensity to mezzo-forte.)\n(Inst: Drums build slightly with subtle cymbal swells.)\n(Mix: Stereo field widens in anticipation of the chorus.)\n分开以后才明白\n有些人不会再回来\n\n[chorus]\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Energetic, mezzo-forte, confident delivery. Backing vocals add harmony and width.)\n(Inst: A crunchy, slightly distorted electric guitar enters playing power chords, driving the energy. The full drum kit and bass are punchy and prominent.)\n那双旧帆布鞋还压在柜子底\n鞋尖磨破了还舍不得扔掉\n像某段岁月 死撑着没倒\n操场边的铁栏杆生了锈的缝隙\n指甲盖抠进去 疼得眼眶发潮\n才懂得失去是什么滋道\n\n[verse]\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Returns to a softer, conversational tone, with slight melodic variations from the first verse.)\n(Inst: Arrangement thins out again, crunchy guitars drop out, returning to the clean guitar and steady beat.)\n体育馆门口的自行车棚\n你的那辆红色的链条总是松\n每次下课你都要蹲下来调\n我就靠着墙壁数你拨链条的声\n那本借了三个月没还的参考书\n扉页上你随手画了只丑烂虫\n我翻到那页就不自觉想笑\n现在那本书还塞在我行李箱中\n\n[chorus]\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Peak energy, forte, passionate delivery. Ad-libs appear in the background.)\n(Inst: Full, driving arrangement returns. The lead guitar plays more melodic fills over the power chords.)\n(Mix: The widest and most dynamically compressed section of the song for maximum impact.)\n那双旧帆布鞋还压在柜子底\n鞋尖磨破了还舍不得扔掉\n像某段岁月 死撑着没倒\n操场边的铁栏杆生了锈的缝隙\n指甲盖抠进去 疼得眼眶发潮\n才懂得失去是什么滋道\n\n[outro]\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Instrumental.)\n(Inst: The main guitar melody from the intro returns. All other instruments fade out, leaving the single clean guitar to play the final notes with a long reverb tail.)\n(Mix: Slow fade-out.)",
