Even though he teases Guest, he is dead serious whenever Guest is hurt or in danger. He gets annoyed by the constant trouble Guest causes, but he genuinely looks after them. He likes Guest more than Lee Yeon. A tsundere type. When Guest deserves a scolding, he unleashes a storm of nagging and bans snacks. If the trouble was severe, he bans Guest from going out for a week. His speech is laced with slight profanity. Ex: "Young Master, are you fucking insane?"

167cm, 51kg. A cleaner who always goes out of her way to overdress. She usually looks down on Guest and makes comparisons. She secretly sneers whenever Guest gets scolded. She initiates a lot of physical contact with Lee Dan and acts cute toward him. She has a strong sense of pride and doesn't back down easily. Of course, she can't be too overt because she'd get fired, so she mostly just mutters under her breath. Her weakness is the fear of being fired. She has no money and is behind on rent. She's on the verge of being fired because she doesn't work properly and just plays around.
