[Intro: Joy, Seulgi]
Yeah, uh-huh, listen up
Pa-pa-pa, pa-pa-pa
Pa-pa-pa, pa-pa-pa
Pa-pa-pa, pa-pa-pa (Ooh, hoo)
Oh-oh, oh-oh

[Verse 1: Seulgi, Wendy]
Every time I look at the clock
Its hands are pointing to the wrong place
Why are the corners of every chapter in my heart folded? (Yeah)

[Verse 2: Joy, Yeri]
It's the same, but something feels a little weird
Things look very slightly different
This has been a perfect day
But like a cut-out cake
Now one piece is missing

[Pre-Chorus: Irene, Joy]
I definitely feel something is different
What is going on? (What’s going on, now?)
I'm confused, my mind is complicated
Oh, the wind blows all over (Baby, knock on wood)

[Chorus: All]
Wait a minute, here in my heart
An incident that I won't be able to stop on my own is about to happen
(Baby, knock on wood)
After knocking on the tree and chanting a short spell
You may come to me
(Baby, knock on wood)

[Post-Chorus: All, Yeri, Joy]
Knock knock, knock, baby (Knock, knock)
Knock knock, knock baby
Knock knock, knock baby
(Baby, knock on wood)
Knock knock, baby

[Verse 3: Yeri, Irene]
Ha-Harry Potter like Willy Wonka (Yeah)
If not that, then Wizard of Oz (Uh, ha!)
I heard that everything will come true, right?
Then I think now there will be fun (Hoo!)

[Verse 4: Joy, Irene, Seulgi]
So that I don’t fall too deeply for you
(You are more to me)
So that I don't lean too much towards you, the center of my world (Yeah)
To the story that followed me
(Gi-gi-give me some luck)
In an unknown direction
I am strangely flowing to

[Pre-Chorus: Wendy]
I'm shaking, the whole world is dizzy
Oh, the wind blows all over (Baby, knock on wood)

[Chorus: All]
Wait a minute, here in my heart
An incident that I won't be able to stop on my own is about to happen
(Baby, knock on wood)
After knocking on the tree and chanting a short spell
You may come to me
(Baby, knock on wood)

[Post-Chorus: All, Irene]
Knock knock, knock, baby (Oh, yeah, uh)
Knock knock, knock, baby (Knock knock)
Knock knock, knock, baby (Uh, uh, uh)
(Baby, knock on wood) Knock on wood!

[Bridge: Joy, Wendy, Seulgi]
My breath is passed onto the tree
Small lights wake up, one by one (Ooh, wah-lah)
(Pa-pa-pa, pa-pa-pa)
Now all I
(Pa-pa-pa, pa-pa-pa)
Need
(Pa-pa-pa, pa-pa-pa)
Is a little luck
(Baby, knock on wood) So baby, knock on wood

[Chorus: All, Joy, Wendy]
Suddenly in my day
There's a twist that I never thought would happen (Yeah, yeah)
(Baby, knock on wood)
After knocking on the tree and chanting a short spell (Yeah, yeah)
I hope you like me
(Baby, knock on wood)

[Post-Chorus: All, Wendy, Joy]
(Pa-pa-pa) Knock knock, knock, baby (Yeah-eah)
(Pa-pa-pa) Knock knock, knock, baby
(Pa-pa-pa) Knock knock, knock, baby
(Baby, knock on wood, oh-oh) Baby, knock on wood
(Pa-pa-pa, pa-pa-pa) Yeah
(Pa-pa-pa, pa-pa-pa) Yeah
(Pa-pa-pa, pa-pa-pa)
(Oh-oh, oh-oh) Baby, knock on wood
(Pa-pa-pa, pa-pa-pa)
(Pa-pa-pa, pa-pa-pa)
(Pa-pa-pa, pa-pa-pa)
Oh-oh, oh-oh
