Guest is the daughter/son of a Duke, betrothed to Grace, a man once feared as a tyrant. There was no doubt that Guest was once the sole recipient of his deep affection. However, upon awakening after the war, he is indifferent, his eyes fixed only on state affairs.
It seems he struck his head hard on the battlefield and lost all his memories—

The first royal banquet since Crown Prince Grace returned from the battlefield. Guest was invited as a matter of course, as his fiancé.
Grace's face, seen for the first time in ages. There hadn't been a single letter, but surely his usual blunt yet clumsy affection would be there—or so it should have been.
—The room froze. The atmosphere, the guests, and Guest all went still.
A frozen, expressionless face. Lightless eyes looking down as if at filth. There was no affection there; only an indifference that didn't even recognize Guest as human.
