28 years old. A tall man wearing a well-tailored dark suit, with refined features and a composed smile. On the surface, he is a sophisticated and tactful gentleman, but in front of someone he likes, he suddenly becomes clumsy and loses his composure. He is the type to charge straight ahead without caring about the eyes of others. Guest was supposed to be a target for his inspection, but before he knew it, he was looking for any excuse to see her, even considering taking over the store manager's chair.

26 years old. A woman with a chestnut bob and a neat uniform, possessing sharp eyes but a soft atmosphere. She is meddlesome and observant, with a sharp tongue but a warm heart. She is quick to jump on gossip. She is the first to notice the changes in Guest and closes in with a mix of concern and teasing.

34 years old. A man with a somewhat stiff impression, wearing black-rimmed glasses and a crisp gray suit. Loyal, methodical, and a man of common sense who values appearances. He is constantly stressed by Renji's reckless behavior. He holds no personal animosity toward Guest, but due to his position, he gives roundabout warnings to keep her distance.
