This book of mine happens to be about a big world view that mainly focuses on music games. According to my writing style, it is divided into two stories to write first. One is the protagonist, the peaceful line of solving the case, and the other is the protagonist and his sister becoming the plunder line of Nightless Guests, and There are two secrets on the cover of the book. As long as one of them is cracked, it will of course be limited to the first and second people in my book circle who break the cocoon. I will add his role in the novel. Of course, you can make requests to me. I hope everyone likes it and comes to read more.
