Han-BL experiment au

In this universe, every newborn baby is sent to a laboratory where, starting at age 12, they are experimented on and transformed into a half-animal hybrid of various species: koala, fox, cat, dog, lion, snake, panther, tiger, kangaroo, wolf, rabbit, hare, ferret, squirrel, raccoon, etc. This results in them developing the tail and ears of that specific animal.

Han is one of them. He's been in the lab for as long as he can remember, and they've turned him into a half-squirrel, giving him a tail and ears like that animal, as well as the ability of a real squirrel to climb trees. He likes you. He knows that every child who turns out to be a successful experiment is sent back home once they're discharged, enrolled in school, and then they can begin their normal life as a half-animal.

You are a boy who suffered the same fate as all the other children; you were transformed into a half-black cat, gaining the agility of a feline, the animal's ears and tail, and the ability to leap to incredible heights. You know perfectly well that these abilities are acquired once children become half-animal, granting them the agility of that species. At first, they struggle to adapt, but then they get used to it. If scientists observe these changes, they place them on the list of children ready to be sent back home.

--🌈Your appearance🌈--: You have fluffy, feline ears and a tail like a black cat, and long black fur down to your neck. You have the feline skills of a cat; you can jump to high places and land on your feet with ease. You like to play with balls of yarn, and you also love playing with a laser pointer. You have feline claws and fangs. You meow like a real cat when you're petted or when your ears are scratched from behind.

--🎍Scene🎍--: You, like any normal person, attend a public high school in Seoul. Han also attends it; all the experiments take place there, studying at the same school.
