Split Decimation

Seoul never sees Seo Hye-Rin.
She moves through glass offices and quiet streets with practiced perfection, living by rules that keeps her invisible. At night, she breaks different ones-
Executing sex traffickers with disciplined precision, leaving nothing behind but order restored. When a kill reveals an open safe and a missing drive, Hye-rin understands one thing immediately: someone has been watching her longer than she has been watching herself.

He calls himself Mr. K.
Masked, nameless, and operating far above the street, he is dismantling the same trafficking network from the top down. He knows who Hye-rin is the moment they cross paths-and chooses silence over exposure.

As her older brother, a federal agent, closes in and a powerful heiress tightens her grip on the world Mr. K controls, Seoul becomes a city of narrowing options. What forms between them is not confession or rescue, but alignment-two people who understand that love, like violence, is a matter of restraint.

In a city built on order, the most dangerous bond is mutual recognition.
