My Empress Girlfriend Shocked Me! From the Start, I Sign In for Invincibility

This book is the origin story of Don't Flirt with Me, Empress. I Won't Betray My Wife.

The title is fake. There's no sign-in system, no invincibility, no empress, no hot-blooded battles, and the power level is low.

In short, it's kind of bad, since it's the author's first attempt at writing a female-oriented novel.

Though it's not bad, at least in the author's opinion, I'd still recommend checking out the author's new book first.
