However, the God of Light bestowed upon him a light magic that enabled him to survive and begin a new, happier life.

Felix was living a tiring life. His only source of joy was an animal cafe. When he could enjoy delicious desserts and the company of little, cute pets. Then, accidentally, a system took Felix's life. As compensation, the system offered Felix to send him to another world. An ABO world with animal characteristics. How could Felix refuse? Then Felix entered the body of a cute rabbit omega. But this new world was still at medieval times! That meant that there weren't any kind of delicious cakes! Or at least not for the commoners. So, Felix's new goal? With the help of his cute little system and a human beggar they would make the best animal cafe of all times!
