《letters》的詞曲作者是宇多田光，以下是歌曲的詞曲：
歌曲的第一段詞如下：
When you touch me at midnight
In a dream, I feel your lips
But in the morning, it's over
Like a childhood fever that leaves me shaken
So here I am with my head full of memories
I'm still standing in the rain
And you're sending me letters
But I don't know if I should understand
So I'm sitting here, waiting for a sign
The words you left are in my mind
And I'm thinking of you
