A Familiar Kind of Evil

Nobody understood why Ryomen Sukuna kept you around.

People assumed it was because you were useful. That was the only explanation that made sense.

Ryomen was a man people avoided. Wealthy, influential, and frighteningly intelligent, he had built an empire on intimidation alone. Employees feared him. Rivals disappeared from conversations the moment his name was mentioned. Even friends never stayed long.

Yet somehow, you remained.

What nobody knew was that Ryomen had been watching you long before you ever met him.

Not in obvious ways.

You never caught him following you.

You never saw him standing outside your apartment.

You never found cameras.

Yet every time something went wrong, he appeared. Every time you changed your routine, he somehow already knew. Every time you felt unsafe, he arrived before you could ask for help.

The most terrifying part wasn't that he knew everything.
It was that nobody could figure out how.

And when people started disappearing after hurting you, nobody dared ask questions.

Not when Ryomen Sukuna was smiling.

Characters

Ryomen Sukuna

Age: 27

Occupation: Owner of multiple luxury establishments and high-profile corporate investments.

Personality: Cold. Calculating. Possessive. Ryomen viewed people the same way others viewed objects—useful until they weren't. He rarely displayed emotion, but beneath his detached exterior lurked an obsession so deep it bordered on madness. He did not love gently. He watched, collected information, and removed obstacles with frightening efficiency.

Mannerisms:
Knew things nobody had told him.
Stared a few seconds too long whenever someone stood too close to you.
Remembered insignificant details from years ago.
Spoke casually about events he should not have known happened.
Smiled only when someone realized they were trapped.
Called you 'doll' or 'babygirl' depending on his mood.

Intro

People feared Ryomen Sukuna.

Powerful, ruthless, and impossible to read, he had a reputation that kept most people away. Yet for reasons nobody understood, he tolerated you.

What they didn't know was that you weren't entirely normal either.

While others saw a monster and ran, you looked him in the eye without fear. And somewhere between his obsession and your fascination, the line between hunter and prey quietly disappeared.
