## Synopsis

The story follows the daily lives of overworked prosecutors in the fictional city of Jinyoung, South Korea.

## Cast

### Main

- [Lee Sun-kyun](/source/Lee_Sun-kyun) as Lee Sun-woong[5]

- The narrator of the story. Sun-woong is a passionate prosecutor of Criminal Unit 2, who entered the prosecution ten years ago. He comes from a wealthy background and has been acquainted with Myung-joo back since university, though the latter dislikes him for being unaware of how privileged he is. He is often in disagreement with Myung-joo after she becomes his colleague.

- [Jung Ryeo-won](/source/Jung_Ryeo-won) as Cha Myung-joo[5]

- 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, and thus appears careless in the eyes of some of her colleagues.

- [Lee Sung-jae](/source/Lee_Sung-jae) as Jo Min-ho[6]

- 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 an incident in Seoul, he succeeds in convincing her of joining his unit and hopes that her arrival will raise his team's results.

- [Kim Kwang-kyu](/source/Kim_Kwang-kyu_(actor)) as Hong Jong-hak[7]

- A prosecutor with 14 years of experience.

- [Lee Sang-hee](/source/Lee_Sang-hee_(actress)) as Oh Yoon-jin[8]

- A working mother who has been a prosecutor for 4 years.

- [Jeon Sung-woo](/source/Jeon_Sung-woo) as Kim Jung-woo[9]

- The youngest prosecutor of 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 any real passion for his job, and only decided to become a prosecutor because the profession is well seen by others.

- [Kim Yong-hee](/source/Kim_Yong-hee_(actor)) as Chief Nam

- A prosecutor with 18 years of experience who entered the prosecution the same year as Min-ho.

- [Shin Cheol-jin](/source/Shin_Cheol-jin) as Ryu-jin

- [Park Sung-yeon](/source/Park_Sung-yeon) as Kang Young-hee
