Art may not seem like much at first but it's so expressive. I love how the artist draws the animals, many times I can see them drawn weirdly deformed but here they are all so amazing. This style kind of remind me of Mr 100% Perfect where the style also seems simple yet the faces of characters are very expressive which is quite difficult to do.
I also like the plot, it's very cute! I recommend reading this.
