Seon Yul-hee, a police inspector who becomes the patrol team leader in the small naval city of Jinyang, meets Jin Hae-rok, a man with platinum-blonde hair and violet eyes. Though her instincts warn her that he is a man she should avoid at all costs, he visits the precinct almost daily to flirt with her. A murky upbringing, an unknown source of wealth, and an unsettling gaze that pierces through people as if aiming a gun. "Let's date. Let's play at romance." And a proposition that leaves her no room for refusal. Setting aside even her own moral code, Yul-hee reluctantly enters into a forced romance with the man for a greater cause.
