Japán:
Tooku Tooku Omoi hatenaku
Futari ga Muzaki ni waratteta
Ano koro ni modoreru nara…

Konagona ni kudaketa
GLASS-zaiku no you na
Omoide no kakera wo atsumeteru
Daiji na mono wa itsudatte
Nakushite kara kizuku yo

Dou ka Dou ka Jikan wo tomete
Kimi no omokage wo kono mune ni kizandekure
Moshi mo Moshi mo Yurusareru nara
Subete wo gisei ni shite mo ii
Ano egao wo mou ichido…

Angol:
Far away, far away, our thoughts are ceaseless
If we can go back to those days
Of when we laughed innocently together…

It broke into pieces
It's like a work of glass
I'm gathering up pieces of my memory
You realize those important to you
After whenever you lose them

Please, please stop the time
And carve your silhouette onto my chest
If, if it's allowed
It's okay even if I sacrificed everything
For that smiling face once more…
