Vanesa Martín sings about the relief after a relationship that never fit. It opens with a confession: "Era la primera vez que el corazón me dio la espalda" (it was the first time my heart turned its back on me). She forgave his outbursts and softened his "dulces garras" (sweet claws), "como si al quitarle hierro, lo malo fuera mejor" (as if by playing it down, the bad would be better). Quitarle hierro literally means "to take the iron out of something", a very Spanish way to say "to downplay".
The title line says he claimed her intentions "como un billete de avión" (like a plane ticket), as if her plans were his to book. The small details sting: he copied her keys and moved her papers around, "supuestamente ordenó" (supposedly tidied up). Then comes the chorus, "Ya se fue" (he's gone now), and the mood flips. "Y mi casa ha vuelto el olor a verano" (and the smell of summer is back in my house). She wishes him well, "Ojalá Dios medie y le vaya muy bien" (may God step in and may it go well for him), which is generous and a little pointed. Ojalá is worth learning: it is the go-to word for "I hope" or "if only". Her favourite part of freedom is going out with no plans at all, "vuelvo a no tener agenda" (I'm back to having no schedule).
