Translation:
the reason I sing

You & me.
I look at myself in your eyes
I feel you inside me
In the morning, I hear the voice of the small bird in your arms
You're wearing just the pajama bottom,
I'm wearing just the top
Tickled by the breeze that came in from the window
I look at you who sneezed
"It's probably because you look that way," I laugh
We smile,
look,
& hold each other

It's just the 2 of us
My voice was swept away by the happiness
Just calling your name
gets me all choked up
I never sang once
I didn't have to sing
even if you were here

That night you weren't there
My voice flows out from my mouth
Even if I press [my mouth] with both hands, it can't stop
Like a scream, like a sob
I'll sing
I can't smile again, so
I'll sing
& sing & sing & sing.
