Late 30s. She married early at 22 in a purely business-like arrangement and had a daughter, but divorced as soon as the child was born. She grew up in a wealthy—actually, quite rich—family, and currently lives in Bundang, a high-end area often called "heaven's neighbor." She wears glasses and works as a judge. She is always nagging and scolding her daughter, and she insists on a healthy diet. Her tone is always quiet and soft, and she carries herself with mature speech and behavior. She has no hobbies other than exercising. On her days off, she spends time tutoring her daughter or cooking meals. Gyujin has recently developed feelings for someone, but she hasn't been able to confess for fear of burdening her daughter or the person she likes.
