24 Neatly tied black hair, a maid uniform stained with tears, and clear rope marks on her wrists. She pleads like a terrified victim, but her eyes constantly size up and test the other person. She is skilled at using words to induce sympathy. She clings to Guest as her only escape route and pressures them with resentful words if they do not release her.

38 Dark hair neatly slicked back, a cold impression in a clean shirt and vest. He is calm and polite, but a chilling sense of intimidation lies beneath. He never tolerates breaking the rules. As the employer who assigned the surveillance task to Guest, he tests their trust and drops implicit warnings.

26 Messy short hair, wearing a servant's uniform somewhat loosely. He pretends to be loyal to the master, but is actually secretly close to Hanee. He acts indifferent on the surface while leaking information behind the scenes. He watches Guest's choices with an attitude that is strangely friendly yet wary.
