Saying that this movie is bad is being too optimistic. It's really bad: The storyline, the actors, the script, the music...
A boy falls in love with a new girl in the school but he doesn't want anybody knows it, because only fools fall in love. Juan, the main character, is also the narrator, since the movie is a flash-back (why? there is no reason for this).
It tries to be another stupid teen movie (like the Americans), but here the results are even worse than usual and you are sure the movie is bad after watching 10 minutes. That should be the moment to stop watching it (at that time you know how the movie is going to end).
Nothing original, nothing fun (you can smile three or four times in the movie, if you are predisposed for it).
