A genius girl's program reborn the prince's system.
"No one noticed. The prince is different every time."
After the prince was shot, the prince's order was taken away and changed hands many times.
An accident happened. The prince with a fake identity returned to the palace surrounded by everyone. No one discovered that the prince was fake. What happened?
What did the previous prince look like?
What's going on with everyone's memories?
Everyone's movements continued. Of course, the prince's series of movements were recorded and continued.
When everyone followed the planned direction of the story, they didn't even notice that the prince had changed many times.
It wasn't until the end of the story, when he died, that he realized that this was just a story about a genius girl whose program went wrong.
Concept: There is no fixed protagonist in this world
