Despertam comes from the verb despertar, meaning "to awaken" or "to stir up." It's a beautifully evocative word for describing how someone's words can rouse deep, often hidden, feelings.
In this song, Sara sings "Essas tuas conversas / Que sabes que me despertam" (Those conversations of yours / That you know awaken me). She's confessing that even though she pretends not to be affected, the other person's words have the power to stir her emotions and desire, making it a perfect word for the song's theme of secret, undeniable attraction.
Sem Ninguém Saber paints the thrilling picture of a secret romance where both lovers play a teasing game of pretending nothing is happening. The narrator tries to act cool and untouched, yet every word and glance from the other person lights sparks that are impossible to hide. Time feels too short for them to openly show what they feel, so they decide to let their bodies speak while the world stays in the dark.
In this hush-hush adventure, the couple surrenders to desire, letting their hearts race and their imaginations blur the line between fantasy and reality. They agree to meet, connect, and then go back to being strangers the next day, keeping the passion alive behind closed doors. The song captures that mix of excitement, urgency, and playful secrecy that comes with a love story lived "without anyone knowing."
