The Villainess Enjoys Her Seventh Life as a Free-Spirited Bride (hostage) in a Former Enemy Country - Chapter 121.2

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

The dawn era after the end of the half century has gradually rebuilt the order, abandoned civilization, and is full of undivided violence and desire.
The noble and powerful pioneers are in charge of the city, and the evil and mad plagues are in the wilderness.
Pure human beings who cannot mutate are the weakest, dominated by the rulers of the pioneers, and are not as good as animals in the wilderness.
A purely humanized young man with a worldly experience has quietly entered the WTO, holding a three-foot long knife and a long-distance desire to boil in the world of purgatory. From the nameless name to the sorrow of the Supreme Court, the name of the black ride is resounding!

- Description from Uukanshu (translated)

Sato Yu is a 12-year-old boy. He is a deprived person. His life is depriving. His step father has a large amount of debt.

"In this world, morality is but a thin line away from depravity, and the most captivating tales are often shrouded behind the veil of insanity."

I was just an ordinary guy, living a dull and unremarkable life as an editor.

But when a maniac author killed me for rejecting his novel in a writing competition, I reopened my eyes in a modern fantasy world.

"Hmm? Wait, this world…."

But fate, being a prude little bitch, played a twisted joke on me.

I reincarnated into the very same novel that I rejected for the competition award, written by the very same author who killed me for it.

Not only that, but I transmigrated into the body of a disowned noble named Lucas Morningstar.

Lucas was a minor antagonist in a novel who served as a stepping stone for the protagonist and their allies.

Arghh….

Of all the people, I just had to be reborn as someone who was despised by the main characters the most at this point in the story?

B-But hey, with my knowledge of the future and understanding of the main characters, I can at least live an easy life!

Right...?

"Yeah, I can work with this!"

Or so I thought until I remembered the ending arcs of the book.

This world is destined for doom!

And not so long after, I started to realize that the novel and the world I transmigrated into might not be as similar as I had originally thought….

*The MC will seem a little bit (ok let's be honest, more than a little bit) foolish in the first 30-35 chaps but don't be fooled. I ask you to read till first 50 chaps before deciding to trash-talk the MC because that's where his borderline psychopathic strategist personality starts to surface.
