A Irmã Do Meu Melhor Amigo

I don't understand why everything ended
I would be very happy by your side
You are the only sister
Of my best friend

The first time I went to your house
It was just to meet your brother
But my eyes looked at you
And my heart fell for you

I was your first boyfriend
I took so, so much care
For you to trust me
But you thought
That I was so bad

Today I won't go to your house anymore
My path so lonely, now I follow
Because even your brother
Doesn't want to be my friend anymore
