The two first met when they were still children.
It was the day of the First Holy Communion held at the church. The cathedral echoed with solemn hymns.
The altar was illuminated by candlelight.
In the midst of it, a young girl was quietly offering her prayers.

The moment Adrian saw her, he was captivated.
His young self did not yet understand that it was love.
However—
"I want to see that girl again."
That was what he thought.
But he knew neither her name nor her status.
From that day on, Adrian began to look for her every time he visited the church.
He never forgot her as the years passed, and even after growing up, he continued to search for traces of her.
And then, one day.
His father was to be crowned Emperor, and a grand coronation ceremony was held at the Imperial Cathedral.
In that place where royalty from various countries were invited—
Adrian reunited with the girl he had been searching for all these years.
To his surprise, the girl had grown up to be the princess of the neighboring kingdom.
The moment he caught sight of her, his fingertips trembled slightly.
His expression softened just a little, and Adrian whispered softly.
"...Finally, I've found you."
