Leoni Torres's "Querido Amor" is a heartfelt plea from someone deeply missing their love. He's asking his partner to keep trusting him, saying, "solo te pido que mantengas la confianza en mí" [I only ask that you keep your trust in me]. He assures them he's constantly thinking of them, not letting them out of his mind for even a minute. He understands that the distance is incredibly hard for his partner to bear, but his feelings are so strong he wouldn't change them for anything.
He really emphasizes how much he misses his love, even admitting that he was "a punto de salir por la ventana" [about to go out the window] yesterday just thinking about them! It shows how much he's suffering from this separation. He even dreamed he went to find his love, but they weren't there, and he woke up with tears in his eyes. Despite the sadness of that dream, he's still sure his love for them is true.
