[Intro — Member 1 (Falsetto, airy + vocoder)] Aurora spills across the sky, 숨 쉬어봐, 불길이야. [Verse 1 — Member 2 (Smooth Tenor)] Aurora runs the midnight veins, Your gaze cuts deep through quiet planes. 숨결이 닿을 때, I lose my ground, 불안한 마음, but you pull me down. 감춰진 진심이 손끝에 남아, 너의 불빛에 타올라. [Pre-Chorus — Member 1 (Falsetto) + Member 4 (Playful Tenor) harmony] Step closer, lines begin to fade, 금단의 paradise, we’re unmade. 숨결이 닿을 때, I drop my guard, You and I — dangerous and hard. [Chorus — Member 3 (High Range) + Full harmonies] We’re burnproof, baby, even if we fall, 금기 속에 we give it all. Your touch’s a crime, I’ll take the flame, In this fever, we stake our name. 불타는 맘, we scream and call, We burnproof — no fear at all. [Verse 2 — Member 4 (Playful Tenor) feat. Member 2 harmonies] Street echoes thrum, a honeyed snare, Every look a secret we can’t bear. 몰래 피는 꽃처럼 숨겨진 진실, 너와 난 끝없는 청춘의 필연. 이 감정은 독 같아, but it tastes so right, Every scar shines under aurora’s light. [Pre-Chorus 2 — Member 1 (Falsetto lead)] Every border crossed feels holy, 죄의 향기, slowly, slowly. 심장이 타올라, can’t turn away, Heaven closed, but we still stay. [Chorus — Member 3 lead + Group] We’re burnproof, baby, spark and sin, 금단의 문을 넘어 we dive in. Chains fall off where the heat creates, We collide — can’t hesitate. 숨겨진 낙원, feel the call, We burnproof — we risk it all. [Bridge — Member 1 (Falsetto) + Member 2 support] 너의 손끝이 나의 불안이야, 비밀처럼 번져가. If love’s a sin, I’ll testify, 너 없인 난 존재가 없어. 별빛 아래, our hearts collide, Every heartbeat — we come alive. [Rap Break — Member 5 (Trap-Funk tone, distorted bassline)] Bassline grinds under glassy nights, Guitars melt, aurora flicks our lights. 너의 눈빛, like a wire to my veins, Distorted truth, I drink the pain. 심연 속에서 네가 불러, 타락해도 좋아, Sin city pulse — we write our law. Broken beats, ghosts in the air, We confess, we risk, we never spare. [Verse 3 — Member 2 (Smooth Tenor) + Member 4 echo] After hours fold, the skyline hums, Tremors linger where the secret drums. 감춰둔 말들이 밤을 채워, 거리에 남은 우리 기억이 번져가. 너의 손길에 난 또 무너져, But rising ash, I learn to shine. [Instrumental Interlude — falsetto & vocoder textures] (half-measure silence → warped synth arps → metallic conga fill → falsetto spiral) [Pre-Finale Lift — Member 1 lead, all breathe] 타오른 심장, 다시 불러내, 나의 죄를 노래해. [Final Chorus — Member 3 lead, full stacked harmonies, Member 5 ad-libs] We’re burnproof, baby, fever bright, 금기 속에 we steal the night. Your sin, my name, we stake the claim, Ash to flame — we fan the flame. 끝없는 밤에, 우리 불타올라, Burnproof — we’re unbreakable. [Climactic Coda — All (brass + disco drums + glitch synths)] 달빛 속에 every vow confessed, 숨겨둔 마음, 이제 폭발해. We call our faults and wear them proud, Together loud — we shout it out. 영원한 불빛에, our shadows fall, Burnproof — we answer every call. [Outro — Member 1 (Falsetto echo) & Member 2 (soft ad-lib)] Aurora fades into the dawn, 불빛 속에, 우린 사라져가. 너의 숨결, 내 마지막 기도, Burnproof — begins again.
