This song tells a story of heartbreak and transformation. The lyrics describe a woman who was once open to love but is now "Triste y vacía" [Sad and empty], crying over a betrayal. She's changed so much that "ya no cree en nadie" [she doesn't believe anyone] and "no tiene corazón" [she has no heart].
It seems like she's been through a lot, especially since "aquel que le decía que era su amor y su locura" [that one who told her he was her love and her madness] broke her trust. Now, when someone says they love her, "ya no cree" [she doesn't believe it]. The song even says she's "anda arrebata en la calle" [walking around high in the street], and that her experience "la convirtió en algo peor" [turned her into something worse]. It's a powerful look at how a broken heart can change someone completely.
