Aferro comes from the verb aferrarse, meaning 'to cling' or 'to hold on tightly'. It's a strong and evocative verb that goes beyond simply 'holding'.
In the song, the narrator sings, "Que me aferro como un loco a la esperanza que algún día" (That I cling like a madman to the hope that someday). This word powerfully conveys his desperate and unyielding grip on the hope of reconciliation, highlighting the depth of his longing and inability to let go.
Have you ever messed things up so badly that you just knew you were the love of someone's life, and now you're desperate for them to know how much you regret it? That's exactly the vibe of Pandora's "El Amor De Su Vida." This song is a dramatic, almost theatrical, confession from someone who's lost the person they loved due to their own mistakes.
The singer imagines their ex's friends telling stories about how heartbroken they are, how they're "llorando" [crying] all the time and can't even leave the house. But then, the singer gets to the good part: they imagine their ex also hearing how they've kept all the photos and still cling to the hope that one day their ex will remember the "hermosos días" [beautiful days] they shared. The most intense part is when the singer can't help but tell anyone who mentions their ex, "Yo, yo era el amor de su vida" [I, I was the love of her life]. They remember all the intimate moments, like enjoying her caresses and her first kiss, and falling asleep in her arms. But then comes the heartbreaking admission: "no supe lo que tenía, me acostumbré a la rutina y la hice llorar, ese maldito día" [I didn't know what I had, I got used to the routine and I made her cry, that cursed day]. It's a powerful and regretful look back at a love lost because of taking it for granted.
