Baek Nam-Bong (Song Chang-Eui) is known as Dr. Frost. He became a professor in psychology at early age. He is extremely bright, but he has difficulties sympathizing with others due to an injury to his frontal lobe as a child. During the day, he now works as a counselor at the campus counseling center and at night he works as a bartender.
Baek Nam-Bong then begins to work with a teaching assistant, Yoon Sung-A (Jung Eun-Chae) at the counseling center. Yoon Sung-A is enthusiastic with the clients needing counseling. They work together to solve problems who go there for help.
