歌曲:
I look at you, you look at me
I look away, so you can't see
I'm dreamin of you
And you don't even know, you don't even know
That I'm fallin madly in love
With you, with you
And I wish that you were going
Crazy for me too...
And I sit alone in the darkest night
My heart is pounding and I wonder why
Why I am invisible why can't you see
I'm in love with you are you in love with me
You show some signs, but I'm not sure
It's a secret love, and your the cure
I just need to know
What you think about me, about me
Cause I'm fallin madly in love
With you, with you
And I wish that you were going crazy for me too
And I sit alone in the darkest night
My heart is pounding and I wonder why
Why I am invisible why can't you see
I'm in love with you are you in love with me
Don't you think that maybe you and me
Could be a possibility
I just wish that baby you could see, you could see
