Plot Summary of Oh My Ghost Clients

At the heart of Oh My Ghost Clients is No Mu Jin, a labour attorney who–get this—can see ghosts. He’s not your typical hero. Cynical, broke, and largely indifferent to the world, Mu Jin simply tries to make ends meet by freelancing at construction sites and small law offices. But after a near-death experience, he gains the ability to see the spirits of dead workers who still have unresolved labour disputes.

Now, Mu Jin is reluctantly pulled into cases from beyond the grave, where he must fight for justice not just for the living but for the wronged dead. Adding to the chaos is his sharp-tongued sister-in-law Na Hui Ju, the woman who basically runs his life and his office despite having no official job title. She’s all street-smarts, sass, and survival instincts—and let’s just say she’s got her reasons for sticking close to Mu Jin.

Then there’s Ko Gyeon U, a former reporter turned quirky Youtuber obsessed with trending content. While his videos chase views more than truth, even he finds himself touched by the emotional depth of these ghost stories. Together, this unlikely trio takes on the hidden injustices of society—one ghost client at a time. Its supernatural meets social justice, with plenty of humour and heart along the way.
