Starring Shin Hae Sun and Gong Myoung, the drama relies on the classic tension between boss and subordinate, but with an important twist: romance emerges amid internal investigations, anonymous reports, and power disputes within a corporate conglomerate.
With 12 episodes and longer chapters than usual, Love Under Investigation emerges as a robust production for those who enjoy intense stories, complex characters, and that famous "enemies-to-lovers" romance.
What is the Story of Love Under Investigation
The plot follows Noh Ki Joon, a brilliant auditor highly respected within the Haemu Group, one of the largest fictional corporations in the series. Known for his excellent performance in Audit Team 1, he lives at the top of the hierarchy until his career takes an unexpected turn. Without warning, Ki Joon is demoted to Team 3, a sector considered irrelevant within the company.
The problem is that this team doesn't handle major contracts or million-dollar audits. Its function is to investigate cases of internal misconduct, corporate scandals, and ethical issues among employees—from gossip to serious reports involving forbidden relationships.
The person responsible for this change is Joo In Ah, the youngest and most feared executive in the company. Cold, perfectionist, and extremely strict, she leads the department with absolute authority and rarely allows room for error.
Furious with the professional humiliation, Ki Joon decides he will take revenge.
Romance Emerges Amid Investigation
The revenge plan gains momentum when he receives an anonymous report suggesting that Joo In Ah is involved in an inappropriate relationship within the company. Convinced he has finally found a way to bring down his boss, he initiates a secret investigation into her personal life.
However, as the two begin working together daily, Ki Joon's perception starts to change. Behind the rigid and intimidating posture, he discovers a woman marked by pressures, trauma, and difficult choices. Gradually, resentment gives way to admiration and then to a much more complicated feeling.
The drama's strength lies precisely in this emotional transformation: the man who wanted to destroy his boss ends up falling in love with her. This type of construction is highly valued by K-drama audiences, especially among fans of romances like What Happened to Secretary Kim? and Her Private Life, which also explore intense relationships in the professional environment.
