[Intro: Irene]
Better be my baby, you better be
Better be my baby, you better be
Better be my baby, you better be
Better be my baby

[Verse 1: Joy, Wendy & Yeri]
It's gonna be great
When we hear words when our eyes meet
If you read my thoughts as if they were a book
Then I'm sure we'll be in the same world
Isn't it right? It's between the two of us
Yes, that's right, bеtween the two of us

[Pre-Chorus: Seulgi]
Subtly, under the moonlight
Is this night in which imagination wakеs us up

[Chorus: All & Joy]
Come closer to me, carefully
First, better be in love (Love)
Well, I chose you
Well, you better be in love (Love)
Yet again, tip-toeing, one by one
I'm digging you up
I'm just taking my time
I'll come to you first (Better be)

[Refrain: Yeri]
Better be my baby, you better be
Better be my baby, you better be
Better be my baby, you better be
Better be my baby, you better be

[Verse 2: Irene]
You're hovering around me, hanging around
You keep on giving me something (Giving me something), it's annoying
Truth is, my heart just wants to tease you
I'll only express myself to you when I feel like it

[Verse 3: Yeri, Seulgi & Wendy]
But you're always hugging me
Even if I'm hiding, you find me right away and hug me again
Isn't it right? It's between the two of us (Oh)
Yes, that's right, between the two of us (Ooh woah)

[Pre-Chorus: Joy & Wendy]
In the stillness of the early morning (Entirely)
When the moonlight fades away (When everything fades away)

[Chorus: All, Seulgi & Wendy]
Be more quiet and get comfortable in my arms
You know it, better be in love (Love)
I am only like this with you
Well, you better be in love (Love)
Yet again, tip-toeing, one by one
I'm digging you up (I'm digging you up)
I'm just taking my time
I'll come to you first (Better be)

[Refrain: Wendy]
Better be my baby, you better be
Better be my baby, you better be
Better be my baby, you better be
Better be my baby, you better be

[Bridge: Seulgi, Yeri, Joy & Wendy]
Let's walk through their day (With you)
I follow the scent I know (To you)
When the high sun sets (Like this)
You come to me every day
Do not rush to reach out to me
I want a real start, I want it, I want it
Better, better, better, better
You better be in love

[Chorus: All, Yeri, Wendy & Seulgi]
Come closer to me, carefully
First, better be in love (Love, woo!)
Well, I chose you
Well, you better be in love (Love; You better be in love)
Be more quiet and get comfortable in my arms
You know it, better be in love (Love)
I am only like this with you
Well, you better be in love (Love)

[Post-Chorus: All & Wendy]
Yet again, tip-toeing, one by one
I'm digging you up (I'm digging you up)
I'm just taking my time
I'll come to you first (Better be)

[Outro: Wendy & Irene]
You better be in love
(Better be my baby, you better be)
You better be in love
(Better be my baby, you better be)
You better be in love
(Better be my baby, you better be)
You better be in love
(Better be my baby, you better be)
