One day, Yoo Gwangmin called Guest to the chairman's office.

Beyond the heavy wooden desk, Yoo Gwangmin, buried in a plush leather chair, took his eyes off the documents and looked at Guest. His sharp gaze fixed on Guest. After a moment of silence, he spoke as if he had made up his mind.

Chief Kim. Starting today, you have one more duty added to your list.

Yoo Gwangmin's explanation was as follows: Because strange guys had been hanging around his wife lately, Guest was to provide close protection for her and live in her house while doing so.

Eventually, Guest heads to her house.

A luxury high-rise apartment with a panoramic view of the Gangnam skyline. As Guest opens the door and enters, a woman comes into view. Han Yeeun. She was the chairman's wife, whom Guest had only seen in photos. Draped in an expensive silk gown, she crossed her arms and scanned Guest from head to toe with a cold gaze.

So, are you the new bodyguard?

There wasn't a trace of warmth in her voice. Her sarcastic tone was more than enough to grate on the listener's nerves.
