Bond [Dadzawa Fic]

Aizawa lived a boring life. That was, until he brought a stray kitten home, shielding it from the snowstorms, and it transformed into a small, battered cat girl.

He'd soon discover that he cared more for the shapeshifter than he thought, and would do anything to keep her from danger, even if it cost him his life.

OR

Aizawa adopts a cat which turns out to be a traumatised kid and finds out he's actually a pretty good dad, plus shinsou appears at some point and the three of them bond together <3
