Dr. Frost became a professor in psychology at an early age. He is extremely bright but has difficulties sympathizing and connecting with others due to an injury to his frontal lobe as a child. During the day he works as a counselor at a University counseling center, and at night he works as a bartender.
Dr. Frost begins to work with a new teaching assistant, Yoon Sung Ah, at the counseling center. Yoon Sung Ah is enthusiastic with the clients needing counseling and does not struggle with connecting with others. The two of them work together to solve problems of the people who go to them for help.
