Plot
Baek Nam-bong is a handsome, thirty-four year old professor of psychology by day and bartender by night, and he is nicknamed "Dr. Frost" because of his prematurely white hair. He sustained a frontal lobe injury in his childhood, which heightened his reasoning centers to genius-level, but left him unable to feel empathy, love, sorrow and other emotional responses.
Nam-bong also volunteers at the university's counseling center, where he meets the cheerful and meddlesome Yoon Sung-ah, who's on the fast track to graduate early and becomes his teaching assistant. Nam-bong has a love-hate relationship with his colleague Song Sun, a professor with a cold personality who was also his classmate in university. His mentor is Chun Sang-won, the head of the department of psychology. Given his excellent deductive skills, Nam-bong officially (and unofficially) assists veteran detective Nam Tae-bong in solving crime.
