Jin Ah is the former leader of idol group Purple, one of the first generation of girl groups in South Korea and also the most popular at that time. She now hosts the radio program "Wonderful Radio," but the program suffers from low ratings. The show's producer then takes time off to give birth. Her replacement is Lee Jae Hyeok. Jin Ah is late for her first meeting with PD Lee Jae Hyeok. Because of this, PD Lee Jae Hyeok gets an unfavorable impression of Jin Ah and their relationship soon turns worse. During the meeting, PD Lee Jae Hyeok instructs the staff to create a new section for the radio program to increase ratings.
