This is one of the two simultaneously published books from the Harinezumi Camera's designer, Sasaki Mika. Unlike the surreal, "The Hedgehog's Castle," this is a truly heartwarming tale. It is a small tale of coming to understand one's heart, “I'm not going to try to change you to be what I want you to be, but I will love you just the way you are.” Ultimately, the book's theme is about love.
