What’s Wrong With Secretary Kim – Plot, Cast & Ending Guide

What’s Wrong with Secretary Kim is a 2018 South Korean romantic comedy that became a defining entry in the K-drama genre. The series follows the unlikely relationship between a narcissistic vice-chairman and his devoted secretary of nine years, whose sudden resignation forces both to confront feelings they never acknowledged. Aired on tvN, the drama ran for 16 episodes and earned praise for subverting traditional workplace romance tropes while exploring themes of trauma, healing, and personal growth.

Park Seo-joon and Park Min-young headline the cast, delivering performances that critics and viewers consistently cite as a major strength of the series. The show originated as a web novel by Jung Hyun-jung before being adapted for television, with the drama version adding darker backstory elements that distinguish it from its source material. Despite airing in 2018, the series continues to attract new viewers through streaming platforms and remains popular among international audiences discovering K-dramas for the first time.

What is What’s Wrong with Secretary Kim About?

Lee Young-joon serves as vice-chairman of Yumyung Group, a wealthy and notably arrogant executive who has grown accustomed to having his every need handled by his secretary, Kim Mi-so. For nine years, Mi-so has managed everything from selecting his outfits to organizing his entire schedule, earning a reputation as arguably the most competent secretary in the corporate world. Her dedication appears absolute, her patience seemingly limitless, until she delivers news that shatters Young-joon’s worldview: she is resigning.

The announcement throws Young-joon into confusion and panic. Rather than accepting her departure professionally, he becomes convinced that Mi-so must be leaving because she harbors romantic feelings for him. This assumption leads him to pursue her with increasingly clumsy tactics, including hiring a temporary secretary specifically designed to make her jealous. The comedy unfolds through these misunderstandings, with Young-joon stumbling through romantic schemes while Mi-so attempts to establish boundaries he cannot accept.

The premise takes a dramatic turn when the series reveals that both characters share a traumatic childhood history. Mi-so once chased a figure she believed was her mother, only to be kidnapped alongside Young-joon, who had already been abducted earlier. A deranged woman held them captive before ultimately taking her own life in front of both children. Young-joon had protected Mi-so during their shared ordeal, though neither character remembered these events until the drama unfolds their past. This revelation transforms their dynamic from a straightforward boss-employee romance into a story centered on healing from shared trauma.

• Narcissist boss trope subversion through character growth and vulnerability
• Workplace romance balanced with psychological depth through trauma recovery themes
• Mi-so’s empowerment arc receives significant critical attention
• Strong chemistry between leads cited as primary viewing draw
• Childhood backstory revelation fundamentally shifts narrative direction
• Lighthearted tone makes trauma themes accessible for stressed viewers

Why Did Secretary Kim Quit Her Job?

Sources indicate that Mi-so’s decision to resign stems from burnout after years of dedicating herself entirely to Young-joon’s needs. Her stated reason of “personal reasons” reflects genuine exhaustion from a career that consumed nearly every aspect of her life. The resignation is not motivated by romantic feelings for her employer, contrary to Young-joon’s assumptions. Mi-so seeks a normal personal life, ordinary working hours, and the freedom to pursue interests outside of catering to one demanding executive’s every whim.

What Is the Plot Twist?

The kidnapping revelation represents the series’ central plot twist, fundamentally altering viewer understanding of both characters’ motivations. Young-joon’s obsessive need to keep Mi-so close stems from an unconscious recognition of their shared past, while Mi-so’s earlier memory of chasing a maternal figure connects her to the same traumatic event. The deranged captor’s suicide in front of both children explains why neither remembered the full story. This backstory validates Young-joon’s protective instincts while giving Mi-so context for inexplicable feelings of comfort around her employer.

Who Are the Main Cast and Characters?

Park Seo-joon as Lee Young-joon

Park Yoo-sik plays Young-joon’s best friend and adviser, providing comic relief and occasionally offering sound relationship counsel despite his employer’s obliviousness.

Is What’s Wrong with Secretary Kim Based on a True Story?

The genre classification places it alongside shows like Business Proposal and She Was Pretty that prioritize lighthearted entertainment while occasionally venturing into more emotionally complex territory. Reviewers have noted that the series succeeds as escapist content for stressed viewers, offering comfortable predictability in its romantic resolution while still delivering surprising emotional moments through the backstory revelation.

How Many Episodes Does Secretary Kim Have?
