| kan1          =
響く瞬間をただ焦がれてた
そこに箱は無く全てすら無く
そんな言葉で、それだけだった
生きる瞬間をただ見惚れてた
表情が重なる錯覚すら
気のせいだって、言い聞かせるように
| kan2          =
どうしようもないんだ
何しろ君はどうしようもないほど笑ってた
| kan3          =
さよならを告げることも許されないほど
「ありがとう」って溢れた世界には
物語のはじまりがあるけど、僕には見えない
| kan4          =
永遠の定義をここで決めなくちゃ
ありふれた別れ話みたいに成り果てもせず
どこにもいけない
| kan5          =
君に花が咲いて、
きらきらひかって、
幻でしかないのだとしても、
ひとつはふたつで、
そんな理由で、
涙は枯れない
| kan6          =
それでも君は光を追うのだろう
それでも君は光を追うのだろう、なんて

|eng1=
Just waiting for a moment this sound echoes
There’s nothing, nothing at all in this box
Only these words alone
Made me excited for the short time I lived
The facial expressions overlap, creating an optical illusion
Might’ve just been my imagination, but it’s like they’re warning me
|eng2=
There’s nothing to help it
Anyway, you laughed, since there’s nothing to help…
|eng3=
In this world that hates goodbyes so much
“Thank you”s overflow
Each story has its beginning, but I cannot see it…
|eng4=
Let’s decide upon the definition of eternity here
Without ending up talking about us separating
I won’t go anywhere…
|eng5=
You bloomed into a flower,
Shining brightly,
It might be nothing but an illusion,
But my tears won’t dry,
With a reason that,
One is two.
|eng6=
Still, you will chase after the light, won’t you?
Still, you will chase after the light, won’t you? I wouldn’t think…
