Screw it if you dont know the portuguese language just listen and read the lirics in the spoiler

 
I know (you) very well

I know very well
Every trace..
Of your face..
From your look.
Every shadow
From your voice.
and every silence
Any gesture that you do
My Love, i know very well

I know
Any fantasy of yours
And all you don't tell
Or you rather not say.
Let myself guess
Don't tell me that i am the fool
If so, it's better that way
My Love, i know very well

I know
To which allies tou hide to.
I know by detail
Your best and your worst in you.
I know you, mopre than i wanted
In one word i would say
I know you very well

I know
Any fantasy of yours
And all you don't tell
Or you rather not say.
Let myself guess
Don't tell me that i am the fool
If so, it's better that way
My Love, i know very well

I know very well
Every trace..
Of your face..
From your look.
Every shadow
From your voice.
and every silence
Any gesture that you do
My Love, i know very well
