The story is about a mysterious housekeeper, Mita, solved a problematique family. Indirectly, she solved the problem one by one. You will feel some insecure or scare feeling. The OST successly made this drama more mysterious. It's nice to see Nanako acting. You won't regret watching it for sure. This drama tells us that every problem, no matter how big the problem is, can be solved surely. The minus is the last episode. I don't expect the story would end like that.
