I started watching this drama not sure if it would be work, romance or comedy. It's a bit all three of them, but most of it is actually a comedy. The breast jokes would be a bit too much if it wasn't.
The story itself revolves around a "Kabe Onna" (Wall Woman). She's a woman with very small breasts. She's the type who is bothered by it, but won't wear extreme push-up bras to compensate. While breasts are a central theme in the story, it's more about what she goes through with work, her love life, her family, and the people with whom she interacts. The story does lack a focus, and most of the time I was wondering where they were going with it. It felt more like a jumble of short stories with the same characters than a coherent thing. There were some other funny moments though, aside from the breast jokes.
