It is a Spanish song I heard in Spanish class sung by a girl. Her hair was blond or brown. The story line in the music video seems like both a guy and the girl who is singing are spies assigned to kill each other. It is a break up song. When I viewed the video, it was on YouTube. The song siad something about how the girl had enough of the lies he had given her and that all of his promises where empty. It sounded like a country-pop song.
