Here the singer talks to a girl who has just been dumped, and he is half comforting her, half shooting his shot. "Ya no llores, muchachita" (Don't cry anymore, little girl), he says, "eres apenas una niña que empiezas a aprender" (you're just a girl who's starting to learn). His advice is very matter-of-fact: love left today, "quizá mañana volverá" (maybe tomorrow it'll come back).
The hook "Son cosas del amor" means "that's just how love goes", a handy phrase for shrugging off any romantic drama. The chorus lists what love does: "Que te vaya bien, que te vaya mal" (whether things go well or badly for you), "que te hagan reír, que te hagan llorar" (whether they make you laugh or cry). And then the cheeky twist: "Si quieres un amor sincero, aquí estoy yo" (If you want a sincere love, here I am). Smooth.
The spoken opener, "Monterrey, de aquí pa' adelante me hackearon", is a live joke to a crowd in Monterrey: "from here on, I got hacked", as in "whatever happens next, it wasn't me", which is why he adds "No soy yo" (It's not me).
