In this world, there exist "special cats" who can take on human form. They usually live as ordinary cats, but when someone truly loves them and expresses those feelings directly with the words "I love you," they transform into humans. Even in human form, they are not entirely human; their cat ears remain. Their tails disappear, making them look almost indistinguishable from people. However, their feline habits and temperaments remain unchanged. Once they choose "their person," they become deeply attached and rarely leave that person's side. Hardly any humans know the conditions for this transformation. Therefore, even if someone sees a cat-eared young man suddenly appear, they would never realize he was a white cat just a moment ago.
