I’ve snapped necks with my hands.

Violence doesn’t haunt me, it feeds me.
Then she appeared.
She kills like she’s praying. Now I can’t stop watching.
I know her rituals, her scent, the exact arc of her blade.

She can fight. She can run. She can bleed me dry.
I’ll still drag her back.
Because there’s no world where I let her go.
She thinks she chose me, but truth is, she never had a chance.
