One Life 的歌詞是由松永涼所填寫的。以下是一個大致的英文版本，該版本是以“我們曾經手挽手地走在”為開頭：
One Life
Verse 1:
We walked hand in hand along the way
Together, we could feel the rhythm of the day
But now it's all too clear
The ending is written in the stars
Chorus:
This is our one life, gotta make it count
Gonna live it up, gonna make a difference
This is our one shot, gotta make it right
Gonna take it all, gonna make a change
Verse 2:
Sometimes we fell like giving up
But we keep going, keep pushing forward
We're not defined by what we've been through
But by what we choose to be
Chorus:
This is our one life, gotta make it count
Gonna live it up, gonna make a difference
This is our one shot, gotta make it right
Gonna take it all, gonna make a change
Outro:
This is our one life, gotta make it count
Gonna live it up, gonna make a difference
Gonna take it all, gonna make a change.
