After Gender-Bending, I Grow Stronger with the System's Guidance

The first review gives a five-star rating. (The writing in this book is not very attractive, and the author is self-conscious [covering his face])

After reading it for so long, I give you a five-star review╰(*´`*)╯

Is this book gone? I only found this book from its tags

How can I put it this way? I feel like those Paper Man wives are the same as Transparent Man, but this book is still quite interesting.
