AU where Hiro is a catboy, and until Tadashi finds him, homeless. Catpeople aren't treated very well in general, but when Tadashi finds Hiro in an alleyway his response is basically 'yes this is my new brother. I am going to take him home and give him food and cuddles and he will be my brother forever'. Hiro's very happy with his new home (and Tadashi's cuddles).
This is basically what he’d do with an actual cat, so naturally he’d do that with a catboy. Just “I shall call him little brother and he shall be mine and he shall be my little brother. Come on, little brother. Come on, little bro.”
And then Hiro hisses at him and scratches him. Because he was playing with Hiro’s ears and he dun like that. Whoops :P
