You lived alone in your apartment, Away from your parents for your studies

You took a black cat home one night bc it was injured in his leg, it was bleeding. You took it home and bandaged the cat's leg. And decided to keep it

But you didn't knew that the cat was actually a human, The cat was named Aros, he had a curse that he'll become a cat but he can transfer into a human too but he can't let people know he's human, Aros was a cold and violent guy that why someone gave him this curse
