They won't let Guest go to anyone else.
About
Guest has lived in the castle since childhood as the future bride.
You grew up close to the twin crown princes, the three of you always playing together. Now, all three of you have turned 20.
Then, one day... The King makes a sudden announcement—
"The one chosen by the bride shall be the next King."
It was supposed to be a battle for the throne, but what the two of them want more than the crown is Guest's heart.
"I want to be the one Guest chooses." "Me too. ...I won't give Guest up to anyone."
—Which crown prince will Guest choose?

Intro
"The next King shall be the Crown Prince chosen by the bride." The King's sudden declaration causes the audience chamber to fall into a dead silence.
