黙ったままのメールを
手のひらに抱きしめる
いつも何かが足りない
未完成パズルみたい

途方に暮れる夕焼けシーソー
向かい側に君を描いたら

約束も返事もいらないから
君へ君へ繋がらせて
最後のpieceならここにあるの
君の君の光になりたい

誰も本当は知らない
理由とか行方とか
だけど‥大好きなんだよ
言葉なんてちいさいね

ぼんやり浮かぶ星に願いを
ひとつふたつみっつ数えたら

つよく砂を蹴った　走りだした
君へ君へつづく鼓動
笑顔が救うなら笑いつづける
君の君の光になりたい

そっと解けだした　未来が見えた
こんな気持ち初めてだよ
やっと見つけたんだ
ここに私　来た意味を

約束も返事もいらないから
君へ君へ繋がらせて
最後のpieceならここにあるの
君の君の光になりたい
光になりたい

I hold my unrevealing email to you
In the palm of my hand
There’s always something missing
Like an incomplete puzzle

I’m at a loss, sitting on a see-saw as the sun sets
Imagining you sitting on the other end

I don’t need a reply or a promise
Let me be connected to you, to you
The final piece is right here
I want to be your light, your light

No one ever really knows
The reasons or where they’re going
But..I love you
Words are tiny things, aren’t they?

As the stars dimly float up into the sky
I start counting my wishes to them, one, two, three

I kicked the sand hard and began to run
My heart beats for you, for you
If my smile can save, I can keep on smiling
I want to be your light, your light

It softly became clear and I could see the future
I’ve never felt like this before
I finally found
The reason I came here

I don’t need a reply or a promise
Let me be connected to you, to you
The final piece is right here
I want to be your light, your light
I want to be your light
