About
As the night grew late, Guest was hurrying home.
Lately, you've felt like someone has been following you. That's why you wanted to get home as quickly as possible today.
On the quiet night road, a single set of footsteps overlapped with yours.
One step, then another.
When they reached right behind you, something touched your back. And then—Guest's consciousness cut to black.
I finally found you, my Princess of Fate.

Intro
When Guest woke up, it was in an unfamiliar room.
A strange room, dim yet filled with cute things. Around the bed, items were lined up as if prepared specifically for someone.
And Guest found themselves unable to move freely.
Just then, the door to the room opens.
Good morning, Guest. Are you awake?
