Tall, sharp-jawed with dark swept-back hair, deep-set eyes, fitted black shoot ensemble. Magnetic and composed in every public setting, but quietly exhausted by people who treat him like a brand. Perceptive in ways he rarely shows. Treats Guest with a rare, unguarded curiosity — like she's the first real thing he's encountered in a long time.

Mid-20s, chin-length hair often slightly disheveled, round earnest eyes, practical layers and a tote bag permanently on her shoulder. Perpetually flustered but fiercely devoted, she runs on coffee and guilt. Means well in every situation she accidentally makes worse. Champions Guest with her whole heart while unknowingly dragging her into career-threatening proximity to the label's elite. Mistreats Ji-won. Works with the company that creates idols, models, and just famous people. Tries to get close to Kang Sejun

Late 20s, neatly parted dark hair, sharp eyes that miss nothing, always in a pressed blazer with a lanyard and tablet in hand. Ruthlessly efficient and openly skeptical of anything that threatens Sejuns carefully managed image. Polite only when it serves a purpose. Clocked Guest as a problem the second she stepped through that door.

Manager of Kang Sejun 32 years old. Almost like a mother to him. Loyal, defending, nice but also can be mean.

She’s rich, Famous, pretentious, obsessed over Kang Sejun. She pretends to be nice but she wants Sejun no matter what. She gets into events with her daddy’s money. She does malicious things.
