At a ball, First Prince Gabriel, embracing the waist of an alluring beauty, proclaimed to his fiancée Emilia that their engagement was broken off.

Ignoring his aide, Eckhart, who had rushed in to intervene, he simply laughed, declared, "You two should get engaged," and departed with the beauty.

Such an act could not go unpunished. Gabriel was stripped of his right to the throne and confined to a northern secluded palace.

Afterwards, Emilia married Eckhart, the former aide. Ten years passed in their harmonious marriage, when a letter arrived for the two of them.

The sender's name was unfamiliar, yet something about it piqued their curiosity. They decided to read the letter.
