A family in 1960s Japan, a cat named Mii, and absolutely nothing happens. That's the entire show. The Onda household breathes in real time, Sachiko daydreams about her idol, Takushi struggles with math homework, their father checks the baseball scores, their mother plans for a future that feels both distant and inevitable. There's no conflict to resolve, no lesson to learn, just the texture of ordinary life in a specific place during a specific decade, the kind of show that makes you realize you've been holding your breath and didn't know it. If you've ever wanted to sit in a room with people you like and do nothing in particular, this is that feeling animated.

In Matsuyama, a city in Ehime Prefecture on Shikoku, during the Showa 40s (roughly 1965 to 1975), the Onda family goes about its everyday life. Older sister Sachiko is a devoted fan of idol Hiromi Dō. Her little brother Takushi struggles badly with arithmetic. Their father Yoshito works in a factory and roots for the Yomiuri Giants, while mother Natsuko hopes to build the family a house of their own. The household's newest member is a cat called Mii. The show is a short-format comedy and slice of life about this family.
