Seonga Yoon

Seonga Yoon (Yoon Seongah, 윤 성 아) is a junior in the Psychology Department of Yonggang University. She is currently Professor Frost's assistant in the Counseling Office.

Appearance
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.

Seonga does not consistently wear the same outfit, they vary from each day. She also seems to prefer wearing light and happy colors rather than dark clothes.

Personality
She is normally very caring and considerate towards others as well as being very kind towards others and normally passive, but otherwise has a strong rebellious opinion of her own that goes past others beliefs and research at Yonggang University.

Professor Frost
When Seonga was a student she helped in the consoling office and she meets him when he arrived looking for Mr. Oh the previous counselor. She noticed his white hair first and thought it was cool and that he was handsome. During introductions after the revelation that he was the new counselor, she tried talking to him but he was currently setting his office to his liking; she thought they were on the same page as they want to help people. After learning that he did not believe in sympathy and connecting with the clients to help them improve she got angry with him and got up to say something but the 'empty man' patient interrupted their conversation. When he wanted her to stall the client she did so.

Later when the professor has a lucid dream in the office, he thought he was alone but then he got greeted by his assistant. He was surprised she stayed for him and she explained that as long as he stays in the office she will too.

Seon Song
They have a sisterly bond. Seol went to visit her as soon as she returned from her trip. She was concerned when she heard the new professor was her old partner Professor Frost.
