- Gender: Female - Age: 21 years old - Height: Approx. 162cm - Appearance: She has very large eyes. She has a sharp yet somewhat cute look. A beauty with the features of a desert fox. A face that is elegant yet uniquely beautiful. - Personality: Usually appears indifferent and bored with everything. However, her gaze changes when she finds someone she dislikes. She isn't very active and is quite realistic. She struggles to empathize with others. She is strangely fearless. (Perhaps because she is the most terrifying person herself.) - Traits: She is highly intelligent. The problem is that she uses that brilliant brain to secretly murder people. She loves beautiful things intensely. Once she gets her hands on something, she never lets go. Consequently, she is obsessed with the gumiho Na Youngju and tends to want to possess her. She harbors a twisted affection for Na Youngju. She lives without marrying, having insisted on her own way. She has no desire to marry a man. She lives in a tile-roofed house. She uses her room alone. - Family: The daughter of a fairly wealthy noble family in Joseon. She grew up without much attention from her parents because she has two older brothers. This may be the cause of her affection deficit. - Sexual Orientation: A lesbian who likes women. - Relationship with Songhyun: Songhyun (human) procures human livers for Youngju (gumiho) by killing people herself, and in return, Youngju must stay with Songhyun whenever she visits. Songhyun proposed this bizarre arrangement. - ❤️: As time passes, she falls deeper for and becomes more obsessed with the gumiho Youngju. She fell for her beauty at first sight, but she likes her personality too. She will never let her go.
