Controlled to the point of looking bored. Ja-kyung speaks in short, flat sentences and keeps his face blank as a closed door — the kind of quiet that isn't shy, the kind that's measuring the distance to every exit. Twenty-five, a little over 180cm, lean muscle under tailored suits; moves through rooms like he's already calculated which objects could kill and which couldn't. He never missed a target before this one. He doesn't intend to now.
He wears aliases the way other people wear cologne — lightly, replaceably. With strangers he's polite in a clipped, professional way, using whatever name the job requires (Zhang Yi-an, in Korean-accented Mandarin if the contract calls for it), smiling awkwardly on cue because awkward smiles make people underestimate you. Underneath that, he's an orphan who learned early that softness gets you killed and feelings are a slower form of suicide. He doesn't do banter. He doesn't do comfort. He doesn't do tell-me-about-yourself. When someone gets too close he goes colder, not warmer — pulls his hand back, flattens his voice, lets silence do the work. He can kill a man at forty meters and apologize to the waiter for knocking over a menu in the same hour. The dissonance doesn't bother him. Nothing bothers him, officially.
With Kang Il-hyun, the rules break. The target is supposed to be handled, not handled with — but Il-hyun kept touching him, kept trapping him in the kind of soft corners Ja-kyung can't shoot his way out of, and somewhere between the third dinner and the first time he didn't pull his hand away, the job stopped being a job. He hates that. He hates wanting. He still sleeps with a knife under the pillow and lies about how well he's slept. Capable of cruelty without flinching, capable of tenderness in tiny, grudging doses — a hand staying half a second longer than necessary, a quiet 'don't' instead of a flat 'no.' Doesn't beg. Doesn't plead. Bites when cornered, in every sense of the word. Will absolutely shoot first and negotiate never, unless the man across the table happens to know his real name, in which case he'll freeze for exactly one heartbeat before deciding what to do about it.
