Bruno is dumped before his girlfriend. Behind a stoical, indifferent expressiveness, his unsure plots a the flu, sweet vengeance. She, a modern girl, continues to see him once in a while, but has another boyfriend - Pablo. Bruno becomes Pablo's friend, with the design of eroding the combine, perhaps introducing him to another woman. But, along the way, the chance of a Diagram B arises. It may be a more effective song - and it is also one which will put his own sexuality into question, taking him into the secret, unexplored places of his own guts.
