English (Translated):
Just like each minute and each second are different
Day by day, you become new
You’re the first of the first
That means you’re the only one
Your voice that calls out to me Lightly comes and slips into my ear
Your touch that I can feel in my hands
Brings me to the dazzling world that I’ve never been in before
You’re 1 of 1 girl
Only one
You are my answer, without a doubt
You’re 1 of 1 girl
It’s perfect
You’re already incomparable
You’re the only meaning of my world
A person like you has a name of Only One
As if you’ve put on the perfect color, yeah
Like a sweet song that passes my ear
You perfectly match, I keep singing about you
Like the feeling I felt for the first time, always replay (replay)
Your love newly shines
Once again, I’m fallin, fallin for you (come here)
I could never get sick of saying I love you
A sweet kiss
Footsteps that only match each other
Without any warning, our eyes met
Why are you so beautiful?
(Let's go) You’re my baby
You’re 1 of 1 girl
Only one
You are my answer, without a doubt
You’re 1 of 1 girl
It’s perfect
You’re already incomparable
You’re the only meaning of my world
1 of 1 girl
Only one
You fill me up without any empty spots
You’re 1 of 1 girl
It’s perfect
You’re irreplaceable
You’re the only meaning of my world
I’m so deeply into you, I’m changing
When my heart, that is lit up with your light, rises up I will shine on you
You’re 1 of 1 girl
Only one
You are my answer, without a doubt
You’re 1 of 1 girl
It’s perfect
You’re already incomparable
You’re the only meaning of my world
