Yesterday, I received a sudden notice from the editor that this book will be on the shelves at 12 noon today.

To tell the truth, it's unexpected and seems reasonable. After all... It's well known.

According to international practice, I should write a speech when I go on the shelf, but I have nothing to say now, so let's do it.

In short, I am very grateful to my friends who have been rewarding and voting in the past month. This book will be carefully completed according to the preset idea. If you are willing to read it, please read it again.
