"When I grow up, I'll ask my father, and I promise I'll come for you. Until then, keep doing your best."

The boy clung to those words from the girl, Vie, whom he met in his childhood, as a source of strength. Even if it was just an empty promise.

Theodore, the second son of the Earl of Altarton, was burdened with all the paperwork that should have been handled by his elder brother, Roderick. Unable to match his brother, a member of the Royal Capital Guard Knights, in skill, Theodore performed these tasks without complaint, but their parents remained oblivious to this fact. To them, their younger son was merely assisting his elder brother, the heir of the house.

Then, a marriage proposal for Theodore to join the Harvey Margrave family came his way. His father, eager to forge ties with the Margrave family, who were favored by the Royal Family, quickly decided to push Theodore onto them. What awaited Theodore when he arrived at the Margrave's estate was the very girl from all those years ago.
