Story
Julietta, the saint of knowledge, is forced to marry into the Iserta Empire, which is on the brink of defeat, despite knowing she is being removed as a nuisance, due to a 400-year-old promise. Her fiancé, Lukino, is also a young man of commoner origins who has been elevated to the position of emperor. In the worst possible circumstances, the two are touched by each other's kindness, and eventually perform a "miracle" that turns the tide of the war on its head. "I look forward to working with you, partner."
