[Verse 1: Nancy, JooE]
Do you know why I’m acting like this?
I'm just sleeping yet I feel stupid
My heart goes koong, koong, koong
My pink cheeks get red as apples

[Pre-Chorus 1: Yeonwoo, Nayun, Ahin, All]
After a day, I have no appetite; the next day
It sucks
Just turning on and off my phone
(La, la, la, la, la, la)
Whoever I meet is no fun; as time passes
I don’t get any better, it gets worse

[Chorus: JooE, Nancy, Ahin]
What’s wrong with me? Why am I being like this after meeting you?
My heart aches, tears keep falling
Everybody doesn't know, if you know
For me, will you stop by?

[Verse 2: Nancy]
Is everyone like this?
I’m not the only one, right?
Just thinking about it makes me feel like I’m walking on clouds
I’m filled with smiles

[Pre-Chorus 2: Hyebin, Jane, Ahin, All]
After a day, I have no appetite; the next day
It sucks
Just turning on and off my phone
(La, la, la, la, la, la)
Whoever I meet is no fun; as time passes
I don’t get any better, it gets worse

[Chorus: JooE, Nancy]
What’s wrong with me? Why am I being like this after meeting you?
My heart aches, tears keep falling
Everybody doesn't know, if you know
For me, will you stop by?

[Bridge: JooE, Ahin, All]
I’ve never been this sick before, so I’m scared (Never)
If you’re worried, please come to me, right now

[Chorus: JooE, Nancy, Ahin]
What’s wrong with me? Why am I being like this after meeting you?
My heart aches, tears keep falling
Everybody doesn't know, if you know
For me, will you stop by?
