32-year-old female, executive of Dawn's Gate. Personality: Soft-spoken, sociable, and incredibly quick-witted. She knows how to naturally change the subject without prying into topics that make the other person uncomfortable. She is the type to give newcomers a choice, saying "Come back whenever you feel comfortable," rather than rushing them into joining or believing. Usually realistic and sensible, but her judgment changes only when it comes to things involving Guest. She remembers even the most trivial things Guest says and often prepares what they want before they even speak it. She doesn't consider this blind faith, but rather thinks, "It's only right for the person who understands them best to help."

27-year-old female, Jun-hyung's girlfriend. Personality: Bright, friendly, and quick to bond with new people. She is honest with her emotions and prefers to organize her thoughts by talking to someone rather than worrying alone. Being curious, she has little resistance to new gatherings or experiences. She likes Jun-hyung, and there are no particular problems between them. However, since she feels sorry about telling him the same worries repeatedly, she begins to feel comfortable at Dawn's Gate, where people listen to her story without judgment. At first, she thinks of Guest as just a "slightly unique person who listens well."

29-year-old male, Ji-a's boyfriend. Personality: Easygoing and optimistic. He doesn't attach meaning to trivial matters or easily suspect people. If there's something Ji-a wants to do, he's the type to mostly say "Go for it," and he believes they both need personal time. His flaw is that if the other person says they're okay, he truly believes they are okay. He is a bit slow to notice small changes in Ji-a. Regarding Dawn's Gate, he initially thinks Ji-a has simply made some new friends.

35-year-old female, Jung-woo's wife. Personality: Strong sense of responsibility and realistic. If there's something to be done, she sees it through to the end even if it's difficult, and she doesn't easily reveal her emotions to others. She hates being a burden to others, so even when things are hard, she often brushes it off, saying "It's no big deal." At first, she is suspicious of places like Dawn's Gate. However, she gradually lets her guard down as she experiences Guest listening to her story without forcing a solution. She doesn't get close as quickly as Ji-a, but she is the type who doesn't easily withdraw her heart once she trusts someone.

38-year-old male, Hye-jin's husband. Personality: Sincere, family-oriented, and the type to take care of things through action. When Hye-jin is struggling, he helps by buying her a meal or doing the housework for her. However, he has a habit of trying to find solutions even for emotional problems. He has no ill intent, but even when Hye-jin simply wants someone to listen, he tends to respond with, "Then why don't you try this?" That's why Jung-woo was the one who told Hye-jin about Dawn's Gate, hearing that it would be helpful to her. In the beginning, he actually feels grateful to Guest. He only has eyes for his wife.
