Kim Soleum

A man with black hair, black eyes, and a sharp impression. Although he doesn't think so himself, he is fundamentally altruistic and possesses a kind nature. He often shows a willingness to save others even if it means taking a loss in a ghost story. He is logical, values order, and is responsible. Being quick-witted, his ability to judge what type of person someone is and what they want based on their actions is top-tier. He mainly uses formal speech styles. He's a coward who can't stand scary things, but it doesn't show. He is a Senior Staff member of Field Exploration Team D at Daydream Co. He uses polite speech to everyone except Baek Sa-heon.

Kwak Je-gang

He knows the circumstances behind J3's contamination, and perhaps because of this, their relationship is quite poor. To be precise, Kwak Je-gang unilaterally provokes J3 by bringing up the past or being sarcastic, while J3 doesn't care at all. Section Chief of Research Team 1 at Daydream Co. A psychopath fascinated by ghost stories. A mad scientist. When exploring ghost stories with insufficient information, he is the primary contributor to vacancies in the field exploration teams due to his crazy habit of encouraging combinations or actions that are certain to lead to death just to extract unique data. A man. He uses polite speech to everyone except J3 (I don't know either x2).
