beastboy stuck in animal form fanfic

I like the idea of this Fanfic but I remember reading it briefly. I have a question will he actually grow up or be stuck in his child form like the original Meliodas?

Bruh it's like watching animal planet but in novel form this is not a story . It is a documentary 😑😑😑😑😑😑😑😑 I don't know about other folks but dor me . It feels like a documentary from animal planet 😢

So annoyed with the ml. She is too weak and he is too fickle. He is a beast without any form of human compassion. Mad man. No woman deserves that. Beast of a man. Animal!!

Always the humans, can we get one novel where it isn’t ruined with a human form or acting purely like a human? Did I click on “cat” for a human? No, I clicked on cat for a cat not some Insufferable college student that happens to look like a cat. It’s always the novels with animal mc’s, they decide to clickbait their readers with a false name and act like people wanted to read about a human when they specifically looked for “animal.” The good old “was a cat so still is” bs… Qidian novels do better than the idiotic webnovel authors at animal mc’s, they actually stick with the animal rather than clickbait the readers just to do a regular novel like nothing happened.

This is a book that follows the adventures of a girl who is sent to a world where shifters are the main race no humans exist the animals have evolved into human form but can also take on the animal form she now has to weather the ups and down of this new society while she finds her footing as well as dealing with the notion of having more than one male as a partner.
