|kan1=
何度夢をみたことでしょう
何も失うことのない世界
すべて拾い尽くせはしないから ねぇ
|kan2=
外は雨上がりのようで
残る気持ちは水溜まり
さみしさが ちいさく 響く
|kan3=
君はどこで泣いてるの
|kan4=
もう 繰り返す夢終わらせて
幾度願っては 消えて
また スキマ吹く風 諦めて
揺れる心 触れたくて
ひとり 空を見ていた
|kan5=
そうして 偽り重ねては
素顔見せることなく 隠して
やがて 沈む世界に溺れてしまうのね
|kan6=
誰もいない 街の交差点
音なき音 波形にもならない声
鏡合わせ 嘘の通過点
落ちる 一筋の光 そこに
|kan7=
もう 繰り返す夢終わらせて
幾度願っては 消えて
また スキマ吹く風 諦めて
揺れる心 触れて
絡まった糸 ほどけてく
本当の気持ち 気付いてる
また出会えたら 溢れ出す音
のせて歌う 涙色
|kan8=
君の声を聴かせて

|rom1=
nan do yume o mita kotodeshou
nani mo ushinau koto no nai sekai
subete hiroitsukuse wa shinaikara nee
|rom2=
soto wa ameagari no youde
nokoru kimochi wa mizutamari
samishi sa ga chiisaku hibiku
|rom3=
kimi wa doko de naiteruno
|rom4=
mou kurikaesu yume owarasete
ikudo negatte wa kiete
mata sukima fuku kaze akiramete
yureru kokoro furetakute
hitori sora o miteita
|rom5=
soushite itsuwari kasanete wa
sugao miseru koto naku kakushite
yagate shizumu sekai ni oboreteshimaunone
|rom6=
dare mo inai machi no kousaten
oto naki oto hakei ni mo naranai koe
kagami awase uso no tsuukaten
ochiru hitosuji no hikari soko ni
|rom7=
mou kurikaesu yume owarasete
ikudo negatte wa kiete
mata sukima fuku kaze akiramete
yureru kokoro furete
karamatta ito hodoketeku
hontou no kimochi kizuiteru
mata deaetara afuredasu oto
nosete utau namida-iro
|rom8=
kimi no koe o kikasete


|eng1=
For countless times, I dreamt of
A world without anything lost
Because I can't retrieve everything
|eng2=
As if the rain outside has stopped
My remaining thoughts are now a puddle of water
With loneliness resounding quietly
|eng3=
Where are you crying
|eng4=
Just end this repeating dream already
For many times, I hope that it'll disappear
Gave up this relationship that cools down again
I want to touch this swaying heart
Looking at the skies all alone
|eng5=
As layers of fabrication
Hide away my true colors that can't be shown
Finally, I'll drown in this sinking world
|eng6=
In the crossroads of a street without anyone
The unheard sounds and the ripple-less voice
Matched themselves in the mirror upon the checkpoint of lies
A ray of light has landed over there
|eng7=
Just end this repeating dream already
For many times, I hope that it'll disappear
Gave up this relationship that cools down again
I want to touch this swaying heart
Untie the threads tangled together
And realize my true feelings
If we can meet again
Sing out the tear colored sounds
|eng8=
Let me hear your voice
