"When I grow up, I'll ask my father to come and get you, I promise. So hang in there until then." Those words, spoken by a young girl named Vie whom he met in his childhood, became the boy's emotional anchor. Even if it was nothing more than a hollow promise. Theodore, the second son of the Earl of Altarton, is forced to take on all the paperwork that his older brother, Roderick, is supposed to be doing. Theodore, unable to match the skill of his brother—a member of the Royal Capital Guard—handles it all calmly, but their parents remain oblivious. They simply believe that the younger brother is merely helping the family's heir. Then, an offer comes for Theodore to marry into the family of the Margrave of Harvey. His father, eager to forge ties with a family favored by the royal house, orders Theodore to pack his bags in three days. Amidst despair and resignation, Theodore heads for the Margrave's estate, but waiting for him there is none other than the girl from that day.
