Bravely Enter the Back Room Level

This book was not very interesting at the beginning, but after reading it, I felt that the plot slowly changed and became more interesting. I hope it can be done better.

To be honest, there is definitely nothing wrong with the subject matter, but the punctuation marks... Author, tell me if you can use punctuation marks correctly? I found it uncomfortable to read... Also, the number of words is a bit short, but if the author is a primary school student, there's nothing he can do about it.
