It's a webtoon that takes place in a nature reservation. The characters are all animals, but we mostley see them in human form.

We first get to see our mc when he comes to the reservation. I don't remember what kind of animal he is, but I think some kind of feline. The first animal he meets is a musk deer, who tells him (and the readers) what kind of place it is. Then something that I don't really remember happen and they get separated. And the next animal he meets is a black lion, which is our second mc.

During the webtoon we get to meet other animal pairs too. But as I said, these two are our main characters.

You could say that the webtoon is in two parts. With the second one happening in another reservation and with two other animals as our main characters. But since I only read the beginning of it, I don't really remember that one so much.
