[Verse 1: Jae]
You were "you"
I was "I"
We've been living without
Knowing each other
With a "Hi"
Now, it's you and me
It's "us" now

[Pre-Chorus: Wonpil]
With a rather low voice
With a little thrill
With excitement
I walk towards you
And say this word carefully
With hesitation

[Chorus: Young K, Sungjin]
Hi (Hello)
Whenever I say this to you
The word that excites me
Hi (Hello)
After we say this to each other
Our story begins

[Hook: All]
La lalalala
La lalalala
La lalalala
[Verse 2: Young K]
To you, I
To me, you
Didn't mean anything before
But with a "Hi"
You and I
Are together now

[Pre-Chorus: Sungjin]
With a full of joy face
You're looking at me
I walk towards you
And say this lovely word again
To you

[Chorus: Jae, Wonpil]
Hi (Hello)
Whenever I say this to you
The word that excites me
Hi (Hello)
After we say this to each other
Our story begins

[Bridge: Wonpil, Young K]
Ever looking
At each other
Is beyond me
After I say this
It's going to be
Blissful
[Chorus: Jae, Sungjin]
Hi (Hello)
Whenever I say this to you
The word that excites me
Hi (Hello)
After we say this to each other
Our story begins

[Outro: All]
La lalalala
La lalalala
La lalalala
