Answer:
Kaguya will not steal the book
Step-by-step explanation:
In psychology mirrors are used to test self recognition in people and also in animals. mirrors can play several roles in how people function. a mirror reflection can help to develop a sense of self and it can help people to shift their perspectives on how they see things. By looking at her own reflection in the mirror Kaguya was able to reflect on herself and the fact that she is not a thief and not someone that should engage in such a behavior so she had to return this book.
