Premise
Philia is the Saint of her kingdom Ziltonia and engaged to the second prince, Julius Ziltonia. However, Julius sold her to the neighboring kingdom of Parnacorta, which lost their own Saint recently. To her shock, Philia finds she has been overworking herself and that a saint truly doesn't need to take care of all of the kingdom's problems unless consulted. Meanwhile, Philia's younger sister plots revenge against Julius for selling off her sister.
Back in Ziltonia, the country has started falling apart as no one has actually needed to do their jobs properly as Philia was doing too much.
