I Was Shocked by the Empress Girlfriend! Invincible Sign at the Beginning

This book is the origin of "Don't Flirt with the Empress, I Will Not Cheat on My Wife" The title of the book is fake, it is not signed, it is not invincible, it is not an empress, it is not passionate, and it is low in martial arts. All in all, it's a bit useless, after all, it's the author's female debut. Although it's barely good to read (in the author's opinion), I still recommend reading the new book first.
