Romanized:

I wonder everything about us

Tell me what we do
I wonder what we'll be like
Eotteon moseubiljido
And how we be livin' our lives
Seworui yasok ape
Byeonhameomneunjido
Miryeonhage gunggeumhae
(I wonder everything about us)
Salui kkeutjarak hwanghoneul jeopaedo
Gidae eopsi majuhae, love that Yourz
Jeonghaejin dabeun geujeo eopgo
Yeollyeolhi dangdanghage mujiui gobaek jung
Chiyeolhage saratdeon mankeum
Drawing a perfect, you and I
Uri saekchaeneun tturyeothanikkan
So I wonder, and I wanna

And I wonder, wonder, wonder, wonder where we'll go
(Where we'll go)
'Cause I wanna, wanna, wanna, wanna keep you close
(Keep you close)
There's a hundred million maybes but I gotta know
(Gotta know)
We could keep it alive for life

This love, right now
It's all we got, all we need
We're happy right now
So why don't we ride this feeling?
Just dance right now
But don't you stop lookin' forward
Just enjoy it, this love
We can keep forever falling

English translation:

I wonder everything about us

Tell me what we do
I wonder what we'll be like
I don't know what it'll look like
And how we be livin' our lives
In the face of the darkness of time
On the same map
I'm so curious
(I wonder everything about us)
Even when I encounter the twilight at the end of life
Face each other without expectation, love that yours
There's no fixed answer
As much as I lived fiercely
I passionately and confidently confess my ignorance
Drawing a perfect, you and I
Because our colors are clear
So I wonder, and I wanna

And I wonder, wonder, wonder, wonder where we'll go
(Where we'll go)
'Cause I wanna, wanna, wanna, wanna keep you close
(Keep you close)
There's a hundred million maybes but I gotta know
(Gotta know)
We could keep it alive for life

This love, right now
It's all we got, all we need
We're happy right now
So why don't we ride this feeling?
Just dance right now
But don't you stop lookin' forward
Just enjoy it, this love
We can keep forever falling
