Like it’s the first to tick by
Since I was born
This is a new one second
You are special
A one-and-only

Your voice, calling me
Like whispers of the wind
Carries me away gallantly
Softly touching your hand,
I am guided
Wonderfully and naturally

Oh 1 of 1 Girl

Multi-colored like spring,
You wear valued Colors Yeah
And, before I realized it, you’re in full bloom
Comprehensively, right? I move steadfastly toward you

No matter how many times my heart flutters
The sensation Replays
It’s not the same as it appears
From the beginning fallin’ fallin’ for you
Again, I think I’ll fall in love with you
From the beginning
We pass each other on this street corner
In a wave of uncountable people
You, unswayed
Are beautiful
You’re my baby
