Ternura translates to "tenderness" or "affection." It's a beautiful, gentle word that captures a soft, caring, almost maternal quality in how someone treats another person.
In the song, the lyrics say "Que con ternura curas sus fiebres" (That with tenderness you cure their fevers), describing a nurturing love so powerful it feels capable of healing pain. It's a word that carries deep warmth and quiet strength.
"Quién Como Tú" is a duet between Lucero and Luis Fonsi built entirely around envy of someone else's love life. Each verse leans into intimate detail about a woman's routine — "El perfume de su almohada" ("The scent of her pillow") / "Tu lo conoces bien" ("You know it well") — before the hook turns that detail into open admiration for whoever gets to keep her: "Quién como tú" ("Who's like you") / "Que día a día puedes tenerle" ("Who gets to have her, day after day").
The envy never curdles into bitterness. Every verse resolves on the same resigned line — "Y nada tengo yo que esperar" ("And I have nothing left to wait for") / "Aunque me quede en el aire" ("Even if it leaves me hanging") — a toast to someone else's happiness rather than a complaint about his own.
