Searching for a song. Help please!

Hi everyone! It's been a few years since i watched this stunning soap opera and i found it while searching on youtube. I was wondering about one song that wasn't available on the various soundtrack cds released for the original brazilian version.
Has anyone any idea what's the song playing at 06:23 of this video?
I would hugely appreciate it! It already opens at the right spot
