Seong-Ah Yoon

Seonga is a young woman of average height and weight. She has black eyes and long, red hair that reaches her lower back with bangs that cover most of her forehead and stick out in some directions. She has a slim figure and a pretty face to match with lips that are often covered in light pink lipstick. Occasionally, Seonga uses her good looks to her advantage and helps Professor Frost with his cases. An example of this was when she stalled Jeonghyuk Oh so Frost could sneak into his apartment.
