《One Kiss》的詞曲由日本歌手宇多田光一手包辦，其歌詞如下：
Verse 1：
One kiss
Just one kiss
Before you leave me
It's all I'll ever need
Chorus：
One love
Just one love
Before you go
It's all I'll ever need
Verse 2：
I don't want a thousand promises
I only want one chance to prove
That you're not just a dreamer
But a real lover in the morning
Bridge：
So don't say goodbye
And don't tell me goodnight
Hold me like you do before you go away
Pre-Chorus：
Oh my heart starts to race
Oh I feel it accelerate
You and I can't deny the passion in our embrace
Chorus：
One love
Just one love
Before you go
It's all I'll ever need
Outro：
One kiss is all it takes to make me feel complete
One kiss from you is all I ever need.
