It's a sunny day for Fox and Wild Boar. But it's also Mayfly Hatching Day. Wild Boar doesn't really want to interact with Mayfly, because if she dies at the end of the day, he'll be sad. But it happens as it must: Fox, Wild Boar, and Mayfly get to know each other. The mayfly correctly suspects that the wild boar is sad. But the wild boar quickly invents a white lie that the fox only has this one day. And so the mayfly, who thinks she is a Mayfly, tries to give the fox the best day of his life, and the trio sets off on a journey through the forest and into the day.

A fox. A clever, handsome fox. He lived a long time and became old and also a bit forgetful.
