The parts of you that I like
I don’t know why
But you think that those are
The bad parts of you

You’re clumsy and fall easily,
Yet you put up a strong front
Forever and ever, just stay like this
I’ll protect you

Baby one more thing
Right here, by your side
The love you’ve been looking for
Is here, always
Wow wow wow wow
Baby one more thing
When I met you
I even got to know why
I was born, I’m sure of it
Wow wow wow wow

When life gets too hard
Just fall into my arms
You can be a little girl little girl
Crying until you fall asleep

Any dream, any wish
Even the insecurities that you have
Everything, everything’s going to be okay
I’m here for you

Baby one more thing
You’re one of a kind in this world
I will keep loving you
Just the way you are
Wow wow wow wow
Baby one more thing
I’ll help you move on
Surely, even tears can be
Changed into smiles
Wow wow wow wow

You’re the most precious
Person in my life
And if you are happy
That will be my greatest happiness

Baby one more thing
Right here, by your side
The love you’ve been looking for
Is here, always
Baby one more thing
When I met you
I even got to know why
I was born, I’m sure of it
Wow wow wow wow
