Anne's reflections about Peter suggest that she is experiencing a complex mix of feelings towards him. The use of terms like "hypersensitive" and "lazy," along with calling him "His Highness," indicates a playful yet critical attitude. While she may find certain traits of his annoying or frustrating, the use of playful mockery also suggests that she has some affection for him.
Given this context, the most accurate interpretation is that Anne secretly loves him. Her mixed feelings reflect the typical complexity of young emotions, where both attraction and frustration can coexist.
