Synopsis
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.
Cast and characters
Main
- 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. His biological mother was kicked out after contracting a serious illness. As Chairman Jeon steps back from the group due to health issues, he clashes with his half-brother Seong-yeol over succession.[6]
- Hong Hwa-yeon as Park Ah-jung
- Jae-yeol's secretary. She realized that her beautiful appearance can make her life more difficult, so she has kept her guard up. She used to be in a relationship with Ki-jun for 2 years.[7]
