Desgracia is a powerful Spanish word for "misfortune" or "tragedy". It conveys a much deeper sense of sorrow than simply saying something is sad, referring to a terrible event or stroke of bad luck.
In the song, TINI delivers the heartbreaking line, "Y no hay peor desgracia que extrañar lo que nunca pasó" (And there is no worse tragedy than missing what never happened). She uses desgracia to describe the ultimate pain of longing for a love and a future that never came to be.
Have you ever been in love with a friend who just didn't see you that way? This song is for you. TINI and Morat sing about the ultimate romantic tragedy: being the perfect person for someone who is in love with somebody else. The singer is so devoted that she'd rather pretend to be happy for him than lose him completely, saying, "Yo prefiero fingir que por ti estoy feliz aunque no me escogiste" (I prefer to pretend that I'm happy for you even though you didn't choose me). The whole song builds to the heartbreaking and slightly sarcastic title line, "Si tú tan solo me hubieras pedido un consejo de amor" (If only you had asked me for love advice). The implication is clear: if he had asked, her advice would have been to choose her!
This is a song about what could have been. The chorus repeats the phrase "Pude haber sido yo" (It could have been me), listing all the ways she could have been the one in his life. It's full of powerful lines about the specific pain of a love that never got a chance to start. Morat's verse includes one of the saddest lines ever: "no hay peor desgracia que extrañar lo que nunca pasó" (there's no worse misfortune than missing what never happened). It perfectly describes that feeling of mourning a future you imagined but will never get to have.
