I never knew
When the clock stopped and I'm looking at you
I never thought I'll miss someone like you
Someone I thought that I knew
I never knew
I should have known something wouldn't be true
Baby you know that I'm so into you
More than I know I should do
So why why why
Why should we waited
And I I I
I should be waiting
Waiting for someone new
Even though that it wasn't you
But I know that it's
Wonderful
Incredible
Baby irrational
I never knew it was obsessional
And I never knew it was with you oooh
Baby if it's just
Wonderful
Incredible
Baby irrational
I never knew it was so sad
Just so sad
I'm so sorry
Even now I just cannot feel you feel me
Hmmm
So why why why
Why should we waited
And I I I
I should be waiting
Waiting for someone new
Even though that it wasn't you
But I know that it's
Wonderful
Incredible
Baby irrational
I never knew it was obsessional
And I never knew it was with you oooh
Baby if it's just
Wonderful
Incredible
Baby irrational
I never knew it was so sad
Just so sad
I'm so sorry
Even now I just cannot feel you fall
I don't even know now
I'm sure you'll wait for me
Even now I just cannot deny
I just hold on so tight
Until you and I never could breathe
Oh
Wonderful
Incredible
Baby irrational
I never knew it was obsessional
And I never knew it was with you until you tell me to
Baby if it's just
Wonderful
Incredible
Baby irrational
I never knew it was so sad
Just so sad
I'm so sorry
Even now I just cannot feel you feel me
