This song is basically a big, dramatic apology set to music. The singer admits he chased all the flashy stuff in life, thinking “las cosas buenas eran aquellas del mundo fanfarrón” [the good things were the show-off things in the world], and now he knows he was wrong because losing this love hurts more than anything. He calls himself “un tonto” [a fool], says he knows he did damage, and that he probably doesn’t deserve to be loved again. But he still asks for “otra oportunidad” [another chance] like someone who knows he messed up badly, yet refuses to give up.
What makes it fun is how over-the-top and honest he is. He swears he is “rehabilitado” [rehabilitated] and that he doesn’t want “amores de mercado” [market loves, cheap loves] anymore, only real love with this one person. His heart is so desperate it “quiere salirse” [wants to jump out] because it “no puede estar sin ti” [cannot be without you]. He promises “ya no ser sinvergüenza” [to no longer be shameless] and to always stay by their side if he gets forgiveness. It is the classic story of the ex who partied too hard, hurt someone good, and now is ready to risk everything “para hacerte feliz” [to make you happy] and prove that this time, he has actually changed.
