A escondidas is a wonderful Spanish phrase that means 'secretly' or 'in hiding'. It's used to describe doing something without others knowing, often with a playful or clandestine feeling.
In the song, Morat sings, "Ayer jugamos a escondidas con otras intenciones" (Yesterday we played secretly with other intentions). This line evokes powerful nostalgia for a first love, suggesting how a childhood game of hide-and-seek evolved into a secret romance. It’s a poetic way to capture the excitement and innocence of young love.
Ever get a sudden urge to call an ex? That's exactly what's happening in this song. The singer finds himself dialing an old number, admitting he's "llamando porque muero por saber / ¿Cómo estás?" (calling because I'm dying to know / How are you?). He's flooded with memories of their first love at sixteen: afternoons spent pretending to watch TV, the way their connection grew from physical to emotional, and a specific address, number 506, where it all happened.
He remembers all the good things, why they fell for each other, but the reasons they broke up seem to have vanished. The second she picks up the phone, he confesses, "contestaste y ya se me olvidó por qué se acabó" (you answered and I already forgot why it ended). He's left wondering if she still goes on vacation to the same places or if she's still afraid of flying. It's a sweet, nostalgic look back at a first love that still clearly holds a special place in his heart and, as he mentions, in more than fifteen of his songs.
