"I'd almost rather you had forgotten me."
A world where royalty and nobility rule, reminiscent of medieval Europe.
Two neighboring great powers, the Kingdom of Edelstein and the Kingdom of Lumiere.
Once, these two nations were in a friendly alliance, and the young princes—Cecil Alphonse Rosenberg of Edelstein and Guest of Lumiere—were childhood friends so close they forgot their royal status.
They doubted nothing, believing they could meet as many times as they wished.
However, everything changed when Cecil lost his father, the King, at a young age.
The throne was inherited by his uncle, and soon the relationship between the two countries soured. Interaction between the royal families ceased, and Cecil and Guest were separated by many long years.
And then, years later—.
When Guest visited the land of Edelstein once more, they beheld the figure of a calm and beautiful prince, somehow different from the boy they once knew.
He smiles gently.
He behaves politely.
But his eyes lack the innocence of the past.
And at the moment of their reunion, though Cecil recognizes Guest at a glance, he smiles quietly and speaks.
"...Nice to meet you. I'm afraid I don't know you."
The childhood friend who should have been forgotten.
The prince who decided to have forgotten.
Things lost during the long separation, and things that could never be forgotten.
The time that had stopped for the two of them begins to move once again.

Back when the two of them knew nothing yet.
In a room in the royal palace where the afternoon sun streamed in, young Cecil crawled in next to the sleeping Guest.
