|kan1=
あなたは誰なのだろう　こんなに揺れているの
アタシは何故　眠れないのか教えて
|kan2=
あなただけこんなに強く傍にいてほしいと
つまづき　痛みを感じて初めて気づいた
|kan3=
氷もいつかは溶けてゆく
そんな風にアタシもいれたら
こんな悩み事　どこかへと
吹き飛んで　ゆくよ　追いかけて　ゆくよ　何度も
|kan4=
繰り返して　いつの日にか　冷たいからだ抱いて
あなただけに　ほら、みせてあげる
ガラスのようなココロを
|kan5=
あなたには言えないけれど　こんなに震えてるの
流れて雲の行方みたいだよね　見えない
|kan6=
氷もいつかは溶けてゆく
そんな風にアタシは思うの
花びらみたくきれいなまま
この空に　チルノ？　この涙　チルノ？　教えて
|kan7=
欲しいけれど　いつのまにか　遠く離れていく
あなただけは　そばにいるなんて　不器用だけど思ってた
|kan8=
ふわり　ふわり　落ちていく　花びらみたいね
|kan9=
それでも季節は過ぎ　もう一度会えたなら
あなただけに　なら伝えられる
ガラスのようなココロを
|kan10=
いますぐ　会いにいくわ　冷たいからだ抱いて
あなただけに　ほら、みせてあげる　白い雪に舞う花を
|kan11=
ふわり　ふわり　のぼってく　風花を抱いてる

|eng1=
I wonder who you are, as I'm trembling like this
Why can't I fall asleep? Tell me
|eng2=
Having stumbled and felt the pain, I became aware for the first time
just how much I wish for you and only you to be by my side
|eng3=
Even ice will someday melt away
If I can also stay this warm,
all my worries will fly away to some place out there,
while I will chase after them, again and again.
|eng4=
Some day, as you embrace my cold body again,
Come, I'll show you and only you
my glass-like heart
|eng5=
Though I can't say it to you, as I'm shivering like this,
It's like the course of the clouds... I can't see where we're flowing
|eng6=
That even ice will someday melt away,
is exactly what I think.
Am I going to scatter into the sky like some pretty flower petals?
Am I to shed tears over this? Please tell me.
|eng7=
I want you, but before I knew it we were far away from each other
I was naive to have thought that you at least would remain by my side.
|eng8=
We're like flowers falling down slowly and softly, aren't we?
|eng9=
But still, this season will be over, if I could see you again
If it's you, I will be able to tell you about
my grass-like heart
|eng10=
I'll come to see you now. Embrace my cold body
Only to you, look, I'll show you flowers dancing in the white snow
|eng11=
Softly, softly ascending and embracing the flowers in the wind
