Okay, while the 2-Stars may sound harsh, I will explain it.
Grammar and Updates are 3-Stars because they are okay-ish, but I often see mistakes when it comes to he/she or other things. Also, the author doesn't correct these mistakes when they are pointed out, so there's that.
Story Development: I actually like the Story, no doubt about that, but it's nothing special. ( 4-Stars)
And this is where it goes down the drain.
Character Design: The Mc is beyond help when it comes to nearly everything. Of course, this is a reflection of how the Author wants it to be, but this is just WOW.
The Mc is naive, biggest trust factor I have ever seen, has Mood Swings, the Mc doesn't act like one would in the 18th century and it is actually kinda "Cringe"
But the biggest fail was when it comes to the World Background.
Spoiler:
The Author introduces another Reincarnated Person as the FL.
In the Beginning I was like: It:s okay I guess.
But the more I thought about it the more it didn't make sense and I realized how forced it was.
The Author keeps on saying that there is a reason but I highly doubt it because what reason could there be for her to be here?
He could have just introduced a random maid from the same Timline that isn't reincarnated or transmigrated.
The reason I think WB is 1-Stars is because with her everything is messed up.
Why was she allowed to reincarnate? If she is reincarnated then practically everyone should be reincarnated with their memories intact. The Mc got this because the Goddess accidentally killed him( Which I doubt can happen lol), but she? This was just her dying a "normal" death. Nothing special, so this means everybody is reincarnated with their memories intact, meaning there should be other people in the same World as him.
Either everybody gets their own World, but it is shown that this isn't the case.
Meaning that other People should be there as well which messes everything up.
Also, it isn't shown if this is a parallel World ,a Dream World or anything else.
It is just messed up and destroyed every Joy I had when reading this and trust me, I had Joy reading this.
I like the Setting and Napoleon, but the FL destroyed everything.
Aside from the fact that the Mc sometimes uses Words such as "cool" in front of the reincarnated FL before she even told him that.
Which Again highlights the Naive Nature of the Mc.
All in all: Great Potential, but you messed it up and considering that you won't rewrite this, it's a lost Cause
