Itoshii no Monkey

A factory worker, who keeps a pet monkey, is forced off a packed train at the wrong stop. He visits the Ueno Zoo, where the monkeys get agitated at him. One day, in a fit of anger, he writes a resignation letter. However, as he is about to hand it in, he loses his arm in a machine. He releases his monkey in the zoo, but it is killed by the other monkeys. Because of his arm, he is unable to find employment. As a crowd approaches him at a street crossing, he runs away in fear.
