I received a reply from the editor today that the matter is settled, around 10 a.m. on May 13, which is next Friday. To be honest, I was a little nervous in my heart, and when the time came to test the real results, I didn't know if I would be too miserable. I can only hope that the students who like this book will support it.

Recently, everyone has been asking when it will be on the shelves and when it will break out, it will be 5.13. Thank you all for your continued support
