Your Royal Highness, I will eventually save you!

"Is this Her Royal Highness Princess Furnier?"
Litton looked up at Her Royal Highness Princess Funier, the third princess of the Erlasli Kingdom at the grand ceremony. She was dazzling and had a bright smile. However, in the coming coming-of-age ceremony one year later, she will be detected as a witch instead. Imprisonment, betrayal, and the whole country will be in turmoil.
"Your Highness, I will be your teacher from today on."
"Your Highness, remember to dress up well today."
"Your Highness, please remember my instructions, do not touch any related persons or materials related to demonic nature, and stick to and trust the belief in your heart."
......
Litton looked at the girl whose body was covered with blood and dirt. The girl raised her eyes slightly, endless darkness appeared in her usually bright eyes, and her pale face tried to squeeze out a slightly apologetic smile towards him. : "...Teacher, I'm very sorry, I can't listen to you, I can't seem to hold on."
