She was originally a princess, not a fake princess with a princess disease, but a real princess with pure royal blood.
The father is old and unable to take care of the affairs of the country. He has only three daughters in his life. The eldest sister is not interested in the affairs of the country. She married the king of a neighboring country early and became a laid-back queen who likes to hold afternoon tea when she has nothing to do. The second sister has no ambitions. She left the house quietly one night when she turned sixteen and never returned home. She only told her family in letters that she was still alive.
So she naturally became the first candidate for the throne.
The crown on her head was as weighty as she imagined, but before she could speak, she fell to the ground.
When she woke up again, her mind was filled with all kinds of strange memories and things she had never been in contact with. Looking at the familiar and strange place, she no longer knew who she was.
Concept: When a princess takes off her glass slipper, she is still a princess.
