"Uno" likes smoking in the backyard of his house, he enjoys listening to music and dancing alone in the living room. On Saturdays afternoons, he's "The One" because he plays football soccer. Sometimes, "Uno" goes to the Quilmes football stadium with his friend "Bigote" ("Moustache"). They also go out clubbing at night. One night Uno meets "Una" ("She") in a bar and they start a love affair. At the beginning "Uno" finds "Una" quite funny and attractive; they also have a good sex. Their relationship grows to the point that he asks her to live in his house, but although they share good moments, "Uno" misses living alone. Unexpectedly, when "Una" abandons him, he realizes how much he needs her and tries to get her back.
