I used to care about you and I 
I used to care about wrong or right. 

And honestly you're still on my mind
And this love-disease, it's me alive

I can tell by the look in your eyes
You're over me, you're over me
How was I supposed to know
I feel so lost, I'll be so lost

How could I know, my love for you would grow
How could I know, I can't make it on my own
How could I know, I'll be lost and all alone
How could I know, how could I know

While do I get about you and I
If love ain't there, love will die
Any place or any time
Please let us reach inside.

Like the stars will make it harder
I know I will be there

How could I know, my love for you would grow
How could I know, I can't make it on my own
How could I know, I'll be lost and all alone
How could I know, how could I know
How could I..

What more do you need, I am down on my knees
What is wrong, I'll change I promise 
Oh oh ohh how could I know 
how could I know 
how could I know
