[Intro – Eun (whisper)] (Low synth hum, 808 heartbeat) EUN: 네 향기가 아직도 here, 붉은 자국, can’t disappear. I don’t need to ask what we are — I already wear the scar. ⸻ [Verse 1 – Ha-joon (smooth, lower register)] (Dirty-drum rhythm, bass line pulse) HA-JOON: Flashlight fade, midnight hall, 너의 웃음은 벽에 bounce off. Lip gloss smear, sweet like sin, 남은 흔적이 시작인 걸. HA-JOON (ad-lib): Oh baby, you paint me red, 잊으려 해도 replay in my head. ⸻ [Pre-Chorus – Eun (airy falsetto)] (Hi-hat roll, breathy layering) EUN: You say “it’s nothing,” but I know that look, 달콤한 chaos I can’t unhook. 손끝의 불빛 like fate attack, 남겨진 kiss — lipstick on my back. ⸻ [Chorus – Both (harmony)] (Full bass and drums drop, hypnotic tempo) BOTH: Lipstick on my back, yeah, you knew the track, Baby, 우리 사이 멈출 수 없어 like that. Red trace burns where you left your name, 사랑과 죄 그 사이에 flame. EUN (ad-lib): Stay — don’t fade like that, Lipstick on my back. ⸻ [Verse 2 – Eun → Ha-joon (call & response)] (Sub-bass + muted guitar) EUN: Every word you breathe feels slow, 밤이 우릴 감싸 또. HA-JOON: Mirror shows the mess we made, But I don’t care if it stays. EUN: 너의 손길 — a silent crime, HA-JOON: Still I crave that every time. ⸻ [Bridge – Ha-joon (low, whisper)] (Beat drops to just 808 + piano) HA-JOON: 붉은 색으로 남겨진 truth, 지워도 다시 나를 부른 you. EUN (soft echo): Can’t erase you off my skin, I let the memory sink in. ⸻ [Final Chorus – Both / Ad-libs + Choir Pads] (Slow crescendo; synths layer like smoke) BOTH: Lipstick on my back — we can’t turn back, 이 밤의 불빛 속에 길을 잃었잖아. Baby, our fire fades in black, Still you paint me red, like that. EUN (falsetto ad-lib): Like that … like that. HA-JOON (low): Lipstick on my back. ⸻ [Outro – Ha-joon + Eun harmonies] (Music fades to a soft pulse) HA-JOON: 붉은 흔적 사라져도, 기억은 남아. EUN: Love don’t fade … it just hides. BOTH (whisper): Lipstick on my back. (fade out to heartbeat bass)
