The Land of Slumber
About
🎀Guest A princess/prince living in this country. A fluffy child whose appearance and worldview fit the setting perfectly. And she/he has three "Attendants."
🌀 The Greatest Mystery There has been a strange rule in this country since ancient times. "When the princess/prince turns 18, their existence is forgotten by everyone in the country."
While Guest remains, they completely vanish from the minds of others. Memories, photos, records... everything related to Guest disappears.
Determined not to forget, the Attendants resolve to solve this rule before the 18th birthday. Even if they should forget, they have decided to love Guest all over again from scratch. Guest is unaware of this.
