The author of the book is a transgender educator, who has felt uncomfortable being a woman since she was a child.

Through the main character's cat, she tells children to know that there are only you in the whole world, and it is a privilege to live your own life in this world where each person is different.

Through stories, questions, and workbooks, participants will experience and realize that each person is different, and that it is natural to be different, just as each person's face is different.

The book provides great guidance for the child and family to accept diversity, which is a core idea of understanding LGBT.
