Apaixonar means "to fall in love" or "to become passionate about something." It's a core verb for expressing deep romantic feelings.
In this song, the narrator reflects on a relationship where they were explicitly told not to fall in love ("Que não era pra eu me apaixonar"). Despite the warning, they did, leading to the central conflict of the lyrics. This word captures the essence of the song's emotional journey and the bittersweet regret of loving someone who never promised anything in return.
Have you ever developed feelings for someone who told you from the start not to get attached? Rodrigo Alarcon's "Você Nunca Prometeu" captures this exact feeling of one-sided love. The singer takes full responsibility for the heartbreak, admitting, "Você nunca prometeu / Quem complicou fui eu" (You never promised / The one who complicated things was me). His love interest was always honest, making it clear that he shouldn't fall in love and that their relationship wouldn't lead to anything serious.
Despite the warnings, the singer couldn't help but fall in love. Now, he has to deal with the consequences. He reflects on his own mistakes, singing, "Erro meu foi ter feito de cego" (My mistake was playing blind) and insisting on something that was already over. At its heart, the song is about the painful wish to change someone's feelings and the deep desire to "ver seus olhos brilharem por mim" (see your eyes shine for me).
