MTL - Metropolitan System - Chapter 16 Is this about?

“Future Occupation…Demon King.”

Sai Akuto enters Constant Magic Academy to be useful to society and to become a top-ranked national magician. However, a horrible prediction is made on his first day. Thanks to this prediction, the class representative girl hates him, a girl with a mysterious power embraces him, a female artificial human is sent by the empire to observe him, and his school life is otherwise thrown into chaos…

What the hell? That menace who bullied me since I was six years old, actually became a pretty girl after three years of living apart? And she even ran to our agreed duel location to confess to me, hoping that I can become her boyfriend?!

This is a plot against me! There’s definitely an enormous conspiracy behind this! I won’t be fooled by you! Even if you tear up and act all pitiful, I will still disregard you and humiliate you, until you’ve have completely paid back all my childhood grievances!

What’cha lookin’at? There are very reasonable grounds for bullying a girl!

There’s nothing that Yu Wan has in common with her new neighbor– whether it’s charisma, personality, or cooking skills– other than that they both own dogs. Their two cute pets get along well (a bit far too well) and start what seems like a rocky friendship between the two; however, Yu Wan has more important things to worry about. Her wildly popular novel is about to take off into a drama adaptation, but the handsome, mysterious, and callous neighbor- is the director?!

Shen Qingzhou (as he thinks of someone): I’d say three. ]

Three Souls lay in one body,

One soul belonging to a man who had reached the peak, the strongest there ever was, the one who had the talent to do so. Yet he suffered because of his talent. His soul shone as bright as a galaxy once, but now is but a sun. His talents made him the envy of all.

And He lost it all.

The Second soul belonged to a man soon to be the richest in the world.

A man who had his face charred, a man who seemingly had every odd placed against him from the very beginning.

He went against the family that abused him and triumphed over them. Yet he was left broken inside, He craved a release, and the first soul brought him that release.

And he became a psychopath that scared the manifestation of evil itself.

And the Third?

The child born from their souls was anything but ordinary. Cursed with a fate no one wanted. Cursed with the fact that the Universe wanted him dead.

He was born from Chaos And Ice and a fraction of light, Yet manipulated Space.

His abilities were so powerful they were harmful to his body.

His talent is as infinite as the boundless cosmos.

His enemies were greater than one could count.

His luck is worse than shit.

And Yet, he continued to fight. Despite whatever was thrown at him, he would brute force through it or outsmart it, befitting the other two above.

He continued to fight, not believing in the bullshit that was destiny.
