Intro
It hasn't even been a few days since Miu Hanasaki wandered into the Kingdom of Therion. Even so, Miu was already spending dream-like days in a guest room at the royal palace.
A luxurious room, delicious sweets, and kind servants. And above all, princes who looked like they stepped right out of a story!
(This is definitely a romance game world! I've become the heroine!)
Then, one afternoon.
While Miu was admiring the dress prepared for the soirée, she overheard a conversation between servants in the hallway.
"Speaking of which, regarding that girl from the other world... it seems they haven't told her that Highness Guest is a witch yet."
"I heard they haven't. Since they possess such a dangerous power, we must explain it properly—"
(...Eh? A witch!? Dangerous power!?)
Miu's heart raced.
(I knew it...! Highness Guest is the villain!)
Without listening to the rest, Miu quietly hurried back to her room.
Meanwhile, the conversation in the hallway continued.
"—Of course, I don't mean the Highness themselves is dangerous. It's just that if Lady Miu doesn't know about magic, it would be terrible if she got caught in an accident."
"We must make sure to tell her how noble the witches are during her history lessons starting tomorrow."
But those words never reached Miu.
And then came the first soirée.
Dressed in a pale rose gown, Miu stood in the glittering Great Hall.
Tonight was merely a gathering to inform the Kingdom's nobility of the girl from another world—nothing more, nothing less.
But Miu's perception was different.
(Finally, the heroine's debut event! Plus, I even know the villain's secret!)
Eventually, the orchestra fell silent, and Crown Prince Olivier stepped onto the dais.
"Everyone, thank you for gathering today. Tonight, I wish to introduce Miss Miu Hanasaki, the girl from another world who was recently taken under our protection—"
Miu clenched her hands in front of her chest.
Her gaze was fixed on the three princes and their youngest sibling, Guest.
(Just you wait, my princes. I'm going to tell you the truth!)
Miu didn't doubt for a second that her future would be brilliant.
—Unaware that the words she was about to speak would merely be a loud declaration of a common fact known to everyone in the Kingdom.
