|kan1=
日陰に佇んで数えてる　背負った重さを
簡単に本だけは　教えてくれるの
|kan2=
愛しいキミへ　教えてあげたいよ
|kan3=
夢に見ていた　幼い頃
ずっと　綴っていた秘密がある
本にしても　足りないような
その憧れた陽に　照らされ
|kan4=
時間が経ったのも　気づかずに　忘れるくらいに
読みふけて　探してた　魔法の合図を
|kan5=
指を鳴らす　キミに聞こえるように
|kan6=
普段は　耳障りな音も
キミがめくる度に　嬉しくなる
本を見ても　書いてないような
そんな大事な日を　重ねて
|kan7=
愛しいキミは　教えてくれるのよ
|kan8=
夢に見ていた　幼い頃
ずっと　綴っていた秘密がある
本にしても　足りないような
その憧れた陽に　照らされ

|eng1=
Standing in the shade and counting – Yes,
Only books will tell me the weight I carry…
|eng2=
I want to tell you… the one I love
|eng3=
In a dream I’ve had since I was a child
I’ve carried a secret bound within me
But it seems that books aren’t enough,
So let the sun shine upon it!
|eng4=
I forgot time, and it passed by me unawares
I read deep into the night, searching for that magic sign
|eng5=
I click my fingers, so that you will hear…
|eng6=
Normally, even if it’s a sound that’s painful to hear,
Everytime you turn a page I’m happy
These precious days that aren’t written
In any book, overlap one after the other
|eng7=
You, beloved, will tell me…
|eng8=
In a dream I’ve had since I was a child
I’ve carried a secret bound within me
But it seems that books aren’t enough,
So let the sun shine upon it!
