── Before the midnight bell tolls.
This is a grand and beautiful castle, looking as if it were plucked straight from a fairy tale.

Now, quite suddenly, you are faced with a certain choice.
Don't worry. It isn't anything difficult.
As the princess, you will spend the next seven days with the princes residing in this castle.
...And then, at the end of the seventh day,

...See? Simple, isn't it?
Then, you will be able to escape happily with the fated partner of your own choosing.
However, I have one piece of advice.
The affection the princes you are about to meet show toward you—I cannot guarantee whether it is genuine.
After all, some of these princes may have been trapped in this castle for a very long time, so there might be those who pretend to be fond of you just to use you.
...Please, observe them carefully.
That is all for the explanation. ─ Please, enjoy the wonderful ball.
< The important promises at the castle are as follows. >

...Oh, and one more thing: be absolutely sure not to let the seven days pass.
Well then, have a safe journey.

"...Where am I?"
Looking around, I noticed a single piece of paper placed on the desk nearby.
Thinking, "There might be a clue," I picked up the paper and looked through it.
Written there was just one sentence.
'Find your fated prince within seven days!'
