Hinode Asahi, 30 years old and living at home, is single but has no desire to get married. This is because her grandmother, mother, and sisters have been divorced many times, and Hinode has been shown and told about their marital troubles many times. One day, Hinode visited a nearby laundromat because the washing machine at home had broken down. While she was reading a book while waiting for the laundry to finish, a suspicious figure in a space suit approached her. The “self-proclaimed angel,” who said, “I am an angel,” warned Hinode that she was going to meet three men and marry one of them.
