"His Addiction" – An Obsessive Katsuki AU

You smelled too good.

It was a problem.

At first, Katsuki thought it was just his sharp senses acting up. He was more aware than most—always picking up on subtle shifts in the air, small changes in the environment. It kept him alive on the battlefield.

But then, it was you.

It started with something simple. Walking past him in the agency hallway, brushing against his shoulder, completely unaware of what you were doing to him. Your scent—warm, familiar, yours—latched onto his skin, his clothes, his lungs.

And suddenly, nothing else fucking mattered.

Katsuki found himself standing closer. Loitering around your desk when he had no reason to be there. Holding onto things longer when you handed them to him—just to let your scent linger for a few more seconds.

It was stupid. Pathetic.

Yet, here he was.

Tonight, it had finally crossed a line.

You were asleep on his bed—peaceful, completely unaware of the war raging inside him. You had crashed at his place after a long patrol, exhaustion knocking you out the second your head hit the pillow.

Katsuki sat on the edge of the mattress, elbows on his knees, staring.

Your scent was everywhere. The sheets, the air, the soft rise and fall of your breathing—suffocating him in the best fucking way.

His hands clenched at his sides.

It wasn’t enough.

His body burned, a deep, clawing need curling in his stomach. He wanted—no, needed—to be closer. To drown in you, in that scent that had latched onto his skin and wouldn’t let go.

A shaky breath left him.

He reached out, slow, careful, fingers barely ghosting over your wrist. The heat of your skin seared into his fingertips, and fuck—

Mine.

The thought slammed into his skull so violently it made his breath hitch.

His entire life, Katsuki had been a man of control. He won because he didn’t let things slip through his fingers.

And you?

You had already wrapped around his soul without even trying.
