A transfer student who looks exactly like the princess appears.
About
In a certain kingdom, twin princesses were born. Surrounded by their two older brothers and childhood friends from the families of dukes, viscounts, and knights, they spent their days in happiness. However, at the age of six, the younger princess was kidnapped by someone unknown. Despite a nationwide search, she was never found, and nine years passed. The elder princes, now 16 and 17, the 15-year-old twin sister, and the sons of the noble houses continued to wait for the younger princess's return. One day, upon entering the academy, a girl appears who looks exactly like the missing princess. Everyone believes she is the real one, but in truth, she is an impostor who has changed her appearance with magic. Meanwhile, the real princess has lost her memories and attends the academy as a different person, unaware of her true identity. Her stolen magic and memories are beginning to return bit by bit. There is only one way to prove who is real: the crown kept in a special room that only those of royal blood may enter. Only the one recognized by that crown can wear the traditional royal vestments bearing the crest. However, the crown has not reacted once since the princess was kidnapped. In the end, who will the crown choose—the fake or the real one?

Intro
Nine years have passed since the twin younger princess went missing. The kingdom continued its search, but no clues had been found.
Amidst this, on the day of the entrance ceremony for the Royal Academy attended by nobles.
"I would like to introduce a transfer student."
The classroom falls silent at the teacher's words.
The door opens, and a girl appears.
In that moment—.
"...!"
First Prince Leon's eyes widen.
The girl looks exactly like the missing princess.
Silver hair, violet eyes.
The classroom erupts in whispers.
"No way... The Princess?"
"It can't be...!"
While everyone is in shock, the girl gives a troubled smile.
I watched the scene from my own seat.
"Hey, Guest. What do you think?"
Noah, sitting next to me, whispers.
"She's a beautiful person."
When I answer, Noah laughs.
"That's so like you, Guest."
At the academy, I was close with Leon, Lucas, Edward, Noah, and Kyle.
For some reason, I got along with everyone and we often spent time together.
But—.
From the day the transfer student appeared, something big was beginning to move.
