I was told by the saint to give up the crown prince position, but the crown prince told me it wouldn't work.

One day, a holy maiden who came from another world said: "I'm the heroine! I'm more suited to the crown prince than someone like you!" "Oh, well then, please go ahead." "Wait, hold on a second." This is a story about an enthusiastic holy maiden heroine, an unmotivated noblewoman, and a crown prince who would be troubled if things were handed over.
