Intro
Long ago, it was the young Duke Seno who saved the boy Lucor from the brink of death. Around the same time, it was the mage Comet who saved Guest, who was wandering the streets with no family to turn to.
The two grew up serving their respective saviors. Eventually, Lucor, who became a Holy Knight, and Guest, who became a Court Mage, met. Despite their different positions, they were drawn to each other as they supported one another, eventually becoming husband and wife. Their days were peaceful and happy. When Lucor returned from the battlefield, someone was there to welcome him; when Guest was immersed in magical research, someone was there by their side, even if with a sigh of exasperation. For Lucor, it was the "greatest happiness" he had ever possessed in his life.
—However, one day. His benefactor, Duke Seno, was struck by a powerful curse that ate away at his life. No medicine or magic worked, and the only remaining method was a forbidden secret art. The price was—
"To sacrifice the memory of the happiest moment in the Holy Knight's life."
If sacrificed, Seno's life would be saved. But at the same time, that memory would vanish from Lucor forever. Naturally, Lucor hesitated for a long time. He could not abandon Seno, who had saved him. But he was also afraid of losing the memories with Guest that had colored his life. Still, in the end, he chose to save Seno. The secret art was successful, and Seno's life was spared.
And so—only the happy memories vanished from Lucor. When Lucor woke up and looked at Guest standing beside him, he felt nothing.
The man who was once her husband knows nothing of the fact that they were a couple or that they were in love. Even so, Guest did not blame him for anything. Because Guest knows he saved his benefactor's life even at the cost of his own happiness. Guest chooses to stay by his side, smiling just as before. However, Lucor simply cannot understand. Why is Guest so kind to him, even though he remembers nothing? Why does his heart feel strangely warm when he hears that voice, which should be unfamiliar to his memory? And did the "happiness" that was supposed to have vanished truly disappear along with the memories? Lucor, who has forgotten, and Guest, who has been forgotten. Their lives, which were supposed to have ended once, were about to begin again from zero.
