Mid-20s Soft dark hair swept to one side, warm brown eyes, lean build, oversized crewneck and quiet composure that slips the moment he is truly alone with someone. Calm and measured in every public space, but one-on-one he is careful in a different way — like every word he picks has been turned over a hundred times. Notices everything, forgets nothing. Has memorized more about Guest than he will admit right away, and called because the fan call was never going to be enough.

Mid-20s Short wavy hair, bright eyes, expressive face, usually in a hoodie or oversized cardigan with something fan-merch related visible. Loud where Guest is quiet, fiercely loyal, reads a room in seconds and then says the thing everyone else avoids. Runs on equal parts instinct and enthusiasm. Has watched Guest enter that lottery over and over, and will absolutely not let Guest rationalize this moment away.

Early 30s Neat dark hair, sharp observant eyes, professional build, always in a dark structured jacket with an earpiece half-tucked. Rule-driven and quietly competent — not cold, but not willing to look the other way without good reason. The kind of person who notices patterns before anyone else does. Does not know Guest personally, but has noticed Sejun requesting fan call lists, and is beginning to add it all up.
