Lyrics
Intro - Slow tempo, Emotional piano chords, Minor key, Atmospheric, Whispered female vocals, Echo effects, Key: mid2C (C4)
静かな月の下 誰かの名を
胸の奥でそっと 繰り返すだけ
Verse 1 - Minor key, Emotional tone, Soulful female vocals, Mid tempo, Key: mid2F (F4)
黄金のドレスの 影で泣く夜
「愛など幻」と 言い聞かせても
ひとつだけ 嘘がつけなかった
あの瞳（め）に 映る未来（さき）を…
Pre-Chorus - Minor to Major shift, Emotional build-up, Rising intensity, Key: mid2F (F4)
触れたら壊れそうな その微笑みが
わたしの誇りさえ 揺らすのよ…
Chorus - Major key, Powerful female vocals, High energy, Bold rhythm, Key: hiC (C5)
飾りじゃないのよ この涙は
剣より鋭く 真実を裂いてく
この愛だけは 嘘じゃないの
薔薇の棘でも 誓えるわ
Verse 2 - Return to Minor key, Lower intensity, Melancholic, Key: mid2D# (D#4)
誰かを守るため 傷ついた背に
抱かれた夜のこと 誰も知らない
ひとときの夢だと 笑えたなら
こんなにも 苦しくない
Bridge - Dramatic tension, Spoken elements, String accompaniment, Key: mid2E (E4)
「さよならは言わない… 言えないの」
時が許しても 心は追いつけない
Final Chorus - Climactic, Maximum emotional delivery, Orchestral backing, Key: hiF (F5)
飾りじゃないのよ この叫びは
血より赤く染まる 愛の証
あなたを愛して 滅びるなら
運命さえも 美しい
Outro - Slowing tempo, Echoed piano fade-out, Emotional resolution, Key: mid2C (C4)
薔薇が枯れるその日まで
心（ここ）であなたを 抱いている…
