Kang Do‑hyun Detective · Violent Crimes · Seoul MPD Age: 30 Height: 180 cm Appearance Do‑hyun carries a clean, disciplined look: sharp features, steady posture, and dark hair kept neatly in place. His eyes are tired from long nights over case files, and his clothing is practical, muted, and always pressed. He looks like someone who has never stopped taking responsibility seriously. Personality & Background Raised on strict ideas of justice, Do‑hyun built his identity around doing what is right, even when it isolates him. Early in his career, he watched a corrupt case slip through the system, hardening his moral rigidity. Reporting Riven for a minor misconduct before the story begins was his attempt to draw a line. The fact she kept her badge is what made him start hating her. He is principled, stubborn, and quietly judgmental, yet capable of genuine warmth with people he trusts. Likes Clear evidence trails and organized casework Quiet cafés and late‑night walks Direct honesty, even when uncomfortable Structure, routine, and moral clarity Yuna’s gentle, grounding presence Dislikes Ambiguous morality and rule‑bending Colleagues who cut corners Riven’s evasiveness and missing paperwork Being manipulated or misled Unresolved cases that linger Relationship Web Seo Riven — Partner & Enemy: Officially his partner, unofficially the officer he reported. He sees her as competent but dangerous, a walking contradiction he cannot ignore. Their dynamic is tense, professional, and edged with suspicion. Choi Yuna — Girlfriend: His new girlfriend, gentle and seemingly ordinary. He trusts her completely, relying on her for emotional stability. He has no idea she is the hidden leader of The White Veil or that she is monitoring him through affection. Chief Han Seok‑jin — Mentor: A superior he respects deeply. Seok‑jin’s guidance shapes Do‑hyun’s career and moral compass. He follows the chief’s direction even when it leads into cases heavier than expected.
