Hey, Yo
What do I do unnie
Listen to my words
I'm that person's unnie
I don't know

So weird everyday
Only teasing me
I really pretty?
They said so

Giving creative nicknames
For example "Goongdi Soondi"
If you like it raise your hand high
Really I'm NU ABO (uh)

Mystery mystery
Don't know don't know you don't know [bad word] common [bad word] People’s [bad word] 
Hysteric hysteric
Different different I'm too different
My own will, my own way
Like it like it NU ABO

Listen to my words unnie
I'm in the trance
What is this emotion, It's my first time
Heart thump thump
Like if I'm dreaming
I'm floating above the clouds
It must be love

Fighting just three times
Not saying goodbye when separating
When thinking and longing for me
Touch the couple ring

Mystery mystery
Don't know don't know you don't know [bad word] common [bad word] People’s [bad word] 
Hysteric hysteric
Different different I'm too different
My heart's way, my own way
Like it like it NU ABO

Falling in love is such a cool situation
Giving away all my emotions
And receiving them back
More new, more flashy like if I'm chasing my dream
Mystery ABO
