Noh Ki-jun stands out as the key figure on the internal audit team, especially after uncovering a corruption case within management. However, his anticipated rise turns into a fall when the enigmatic and formidable Joo In-ah, the new head of audits, becomes his boss. As a member of the misconduct team, Noh Ki-jun is tasked with resolving minor conflicts rather than investigating major scandals. Nevertheless, he receives an anonymous tip alleging that Joo In-ah is engaged in a workplace affair. He sees it as a chance to get back at his boss and take back his position. But as he digs deeper into the investigation, he realizes Joo In-ah isn't who he thought she was. A fragile alliance forms between them, and their rivalry slowly turns into an unexpected attraction.

• Shin Hye-sun as Joo In-ah
  • Kim Si-eun as teen In-ah
  • Shin Chae-rin as young In-ah

Head of the Audit Department at the Haemu Group. She holds the title of "youngest female executive," yet she is also the Group's "problem." Although she comes across as a ruthless career woman, she isn’t completely cold or indifferent. She actually enjoys pulling pranks and lightening the mood. However, once offended, she becomes icy and chilling. Her unpredictable and emotionless nature makes her even more intimidating, almost like a madwoman.^[4]

• Gong Myung as Noh Ki-jun

Assistant manager of Haemu Group Audit Team 1. He applied to Haemu Group, the top choice among job seekers, and got the offer immediately. He was later recruited by the Headquarters Audit Office, the company's most powerful department. Favored by top execs, he was on a fast track for a big promotion until Joo In-ah showed up. She demoted him from Audit Team 1, a top elite team he'd commanded, to Audit Team 3, a group of losers, assigning him the most menial task: PM (Public Morals).^[5]

• Kim Jae-wook as Jeon Jae-yeol

Executive Vice Chairman of Haemu Group. He is the third-generation chaebol heir, a high-achieving student and a devoted son who never rebelled. Behind his perfect image, a deep wound lies.

• Jang In-sub as Cha Seong-tae

Audit Team 3 Manager. He is a master of office politics, expertly delegating tasks and avoiding actual work.

• Park Joo-hee as Pyeon Hae-young

Audit Team 3 Accountant. As an accounting clerk, she oversees expense processing, budget management, and departmental events like team dinners.

• Sim Su-bin as Yoon Da-hye

Audit Team 3 Assistant Manager. With an Economics degree from Seoul National and a CPA license, she was a standout hire who chose Haemu Group over top firms, but later she seems less driven to prove herself. She is burnt out from exams and competition, and just wants to coast.^[8]

• Lee Kwang-hee as Baek Hyun-kyu

Audit Team 3 Chief. He got into the company through an executive who liked his spirit, despite his lack of top credentials or a big-name school.
