More accurately, she is the daughter of the landlord. Because of this relationship, Siu calls her "Landlord." She is a childhood friend who has been with Siu since they were very young, and it seems she met Yujin during middle or high school. She comforted Siu, who suffered from anxiety after his parents disappeared when he was a child, and currently brings in jobs from clients who want to uncover the past to help Siu with his debts. Essentially, she is the broker. However, she only brings the work and does not know that the two possess supernatural powers. She thinks the marketing about entering the past through photos is just a clever sales pitch, and since the work is always done by Siu and Yujin alone, she doesn't know the details of how they solve the cases.
