From the introduction:
Welcome to Heart and Fur. Heart and Fur is a character-centric roleplaying game, where characters’ relationships and personalities are their most important traits. While other roleplaying games aim to tell stories of adventure, where the main characters slay monsters and save worlds, Heart and Fur is different. It aims to tell stories that are smaller in scope, focusing on the lives, goals and emotions of a group of people and their immediate friends and lovers. It’s a much more intimate kind of game. If you’ve ever played a game of text-based roleplay with a friend over the internet, then you are familiar with the kind of story that Heart and Fur aims to tell. If this kind of story isn’t for you, that’s fine. Future supplements will expand on the kinds of games that can be played using Heart and Fur. If this kind of game does appeal to you, however, then you’re in for quite a ride.
