Luyện nghe bài hát If You Knew What I Know

Oh, if you knew what I
You'd be to let him go
A guy that stays true is one to find
I've heard my old is now on your mind

But if you knew I know
You'd be to let him go
Has he told you of the that we knew?
Or he pretend he loves only you

'Cause if you knew I know
be glad to let him go
Someday you'll know his isn't real
He'll back to me and then how will you feel

he'll cheat on you like he cheated on me
So send him back now while your heart's free
if you knew what I know
You'd be to let him go
