This is the first book I’ve written that has been put on the shelves. Although the performance is terrible, it shouldn’t be abandoned. After all, I’m a person who likes to have perfect attendance.

Up to now, the number of collections of this book is about 2,400. I hope the first order can exceed double digits. I will be satisfied even if it is 10.

I won’t say more. You can just watch my update performance. Although few people have read this far, I think the five updates tomorrow are my sincerity.
