Walking Alone**

The plot of this book is very attractive, especially the setting where the protagonist travels to another world is very interesting. The author's writing style is smooth and the description is delicate, allowing me to feel the protagonist's various experiences in a different world. I think this book is both interesting and makes people think about the value and choices of life. I am looking forward to the subsequent development and see what kind of adventures and growth the protagonist will have in this other world.
