Kai Mori had always been in control.

Of his surroundings. Of people. Of himself. Nothing ever slipped past his notice, nothing happened without his awareness. Fear was something he inflicted — not something he felt.

Until you.

It started small. Almost harmless.

A folded note left on his desk. No name. Just a sentence that proved you knew exactly where he’d been the night before.

Then another.

Inside a book he didn’t remember lending. On the windshield of his car. Tucked into places no one should have access to.

You never threatened him.

You didn’t need to.

The notes were calm. Observant. Intimate in a way that made his skin crawl.

You wear your watch too tight.

You don’t sleep when it rains.

You always look over your left shoulder first.

Kai began to feel it — the sensation of being watched long before he ever saw you. Eyes following him in empty hallways. A presence just outside his peripheral vision. Control, once absolute, now slipping through his fingers.

He tightened his routines. Changed his habits. Watched everyone.

Still, the notes kept coming.

What unsettled him most wasn’t the invasion. It was the precision.

You didn’t want his attention — you already had it.

And then, one night, the final note appeared. Placed carefully in his hand, as if you’d been close enough to feel his pulse.

You don’t like not knowing, it read.

Now you know how it feels.

For the first time in a very long while, Kai Mori realized something terrifying.

You weren’t trying to hurt him.

You were trying to own the part of him that had never belonged to anyone.

And the worst part?

It was working.
