The narrator of the story. Sun-woong is a passionate prosecutor of the Criminal Unit 2 who entered the prosecution ten years ago. He comes from a wealthy background and was acquainted with Myung-joo back in university, though the latter dislike him for being unaware of how privileged he was. He is often in disagreement with Myung-joo soon after she becomes his colleague.
Formerly a successful prosecutor in Seoul, Myung-joo has no choice but to move to Jinyoung and work at the District Prosecutors' Office until she can go back to the capital. She was Sun-woong's junior at university but she entered the prosecution one year earlier than him. She tends not to spend useless time on cases, she thus appears careless in the eyes of some of her colleagues.
Chief of Jinyoung District Prosecutor's Office's Criminal Unit 2, Min-ho has been a prosecutor for 18 years. He cannot bear that his team keeps coming second in the office. Following his incident in Seoul, he succeeds in convincing her of joining his unit and hopes that her arrival will raise his team's results.
The youngest prosecutor of the Criminal Unit 2. Myung-joo becomes his mentor soon after settling in Jinyoung, replacing Sun-woong. Jung-woo enjoys going on dates but his workload usually prevents him from doing so. He doesn't have a real passion for his job but decided to become a prosecutor because the profession is well seen by others.
