Isn't a cat needed

Tsubaki looks like a human, but he's actually a cat who longs to be by his beloved Tma-san's side. He's become a 'long-life cat' for Tma-san, who only sees him as a pet. Tsubaki can only become human when Tma-san truly accepts him. But Tma-san only hears Tsubaki's pleas as meows. How can Tsubaki make Tma-san see him for who he really is?
