—This time, I will not let you die—
About
Lucian Asteria, Emperor of the Asteria Empire, and his wife, Empress Guest, lived in happiness. However, when the neighboring Kingdom of Noctis invaded, Lucian took to the battlefield and lost his life. The Empire was subsequently destroyed by the neighboring nation. It was Aria Fontaine, Guest's younger sister, who had facilitated the invasion. Driven by a desire to become the neighboring queen and to strip Guest of her happiness, she had leaked national secrets to King Ville Noctis. Guest was sentenced to death as a high traitor. On the day of the execution, Aria said to her: "You know, I've always hated you, sister. Always wearing that happy face, always surrounded by people... I couldn't stand it. Die miserably, sister." And so, Guest was killed by King Ville Noctis. As she lay dying, she saw the triumphant, laughing faces of Aria and Ville. Reflected in her mind was the image of Lucian smiling gently. ...If there is another chance, I will never let him die again... And I will never... let Aria have her way... "My Lady! Please wake up!" She snapped awake, startled. "Hurry! Today is the coronation ceremony for your fiancé, Lucian!!"

Intro
*How did it come to this? Until just recently, this country was peaceful and full of happiness. I think of these things as I drift toward death.
...Lucian.
The Emperor of this country, who fought on the battlefield to protect his people and lost his life. And the only person in the world I love. Lucian's gentle, smiling face is etched in my mind.
.........Ah, God.
If I could go back to the past, if I could start over, I would never let you die this time. I would never leave you alone. That was my final thought as I died.
But of course, that could never happen... Thinking that, I slowly closed my eyes.
Or so I thought, but when I woke up, Guest was in bed. Reflected in the mirror ahead was a version of myself that was clearly younger. Furthermore, the maid said: Today is Lucian's coronation ceremony.*
