I am 10 chapters in and I have an inkling feeling that everything about this story will be surface level and allow me to elaborate on this.
Within the first 3 chapters the foundation of the story is set, and the foundation laid is pretty shallow. The FL talks about traits being very important, she explains that traits decide if you are born with carnivore ears and tail or an herbivores ear and tail, it also supposedly decides your taste palette. Why are the herbivore and carnivores separated is not explained, the carnivores don't prey on the herbivores so at this point you could take the animal traits away and just write this as a vegan vs carnivore story, then at least there would be a legitimate reason for the separation of the people and their strong belief system would explain why its hard for them to befriend one another.
The 2nd example is the few moments we are shown animal traits like howling, petting, and tail wagging. Only one character does these things, the child FL is never shown baaing, and her younger brother is never shown acting like a lion, so when these rare characters appear doing it, it comes off as the author trying to fulfill a fetish instead of this just being something that naturally happens within this world.
The story is just humans cosplaying at best, the characters are ok, the story is lacking in depth and doesn't have enough charm to make it a cute fluffy light read either, and the choice to narrate throughout the story makes it closer to a tell instead of show manwha. I rated it under 5 because the story is "just ok," however I didn't even want to read up to chapter 10 but for the sake of trying to give the story a chance before leaving my review I forced myself to chapter 10.
Would I recommend this to others? I would not, I can think of two other books that handled humans with animal traits better than this book, I wouldn't even consider this book in the animal/beastman genre as they are just humans wearing animal ears b.c the author likes ears and tails.
