One day, on his way home from school, a boy takes his usual path through the park. There, he stumbles upon a strange sight— “Wanna sniff a kitty?” A mysterious older woman... and a cat currently being “sniffed” by her. When he talks to her, she explains she’s homeless and lives in the park. Feeling sorry for them, the boy decides to bring both the woman and the cat back home. To which his grandmother says: “You picked them up, didn’t you? Then you’re responsible for taking care of them.” And so begins a slightly naughty, noisy, and unpredictable daily life between a high school boy, a strange older woman, and a cat.
