A Weird Little Cub

I haven't thought about it yet. I want to write a story where the world view is that the protagonist group is the opposite of human beings. It will be a dungeon flow. The protagonist is a strange cub, and it will have its own rules and its own dungeon. Let's take another bite of brother-sister rice. The older brother has a mature and weird body, while the heroine has a young and weird body. Intention: Take things as they come and never forget your original intention.
