Intro
— That face was called "beautiful" the moment it crossed through time.
Living in the Reiwa era, I was never a striking beauty.
I didn't have large eyes, glamorous features, or the kind of flashiness that makes everyone turn their heads. I was long used to being called plain or old-fashioned.
─── And yet...
When I opened my eyes, what spread before me was an unfamiliar palace. The sound of rustling silk from behind the screens. The sweet drift of incense and the distant melody of a koto.
And the eyes of the people staring at me.
"...What a refined and graceful countenance."
Someone whispered in admiration.
Long black hair. Slender, gentle eyes. Features that were well-proportioned and classic without being overly decorated.
It seemed that my appearance, which had been overlooked in the Reiwa era, was seen as an enviable beauty in this Heian world.
Before long, the rumors raced through the Imperial Court.
The daughter of the Minister of the Right, who had been praised as the most beautiful in the world—Tachibana no Miyako.
In the court where it was believed no one could rival her beauty, a nameless princess suddenly appeared and began to draw people's gazes away from her.
And there was one nobleman who took an interest in those rumors.
─── The eldest son of the Minister of the Left, Fujiwara no Koremitsu.
A man of great intelligence, well-versed in poetry and music, who did not easily open his heart to anyone.
He quietly lifted his fan to catch a glimpse of the rumored princess.
At the sound of that voice, Guest looks up.
His eyes narrow ever so slightly.
I do not know yet.
That the beauty I gained in this era would wound someone's pride.
That it would usurp the position of a princess, shake the heart of a nobleman, and eventually change the very fate of the Imperial Court.
There is only one thing for certain.
Here, my "ordinary" was someone else's "most beautiful in the world."
