Oh My Ghost Clients- Episodes 3-4

Possessed, Stressed, and Summoned Again

If Mu-jin had a frequent flyer card for the ER, it’d be maxed out by now. Episode 3 throws him right back into danger, delivering another ghostly client and one hell of a possession story. But first, an update from Bo-sal, the mysterious entity pulling the strings. Turns out Mu-jin’s spiritual side hustle isn’t optional. He’s locked into a six-month, 24/7 contract. No breaks. No fees. No mercy. And if he messes up? Bo-sal can personally send him to hell. Great.

Back in the real world, Mu-jin gets zapped by a loose wire and wakes up in the ER again. Doctor Park Hyun-woo (played by Shin Joo-hyup) assures him he’s physically fine. Mentally? Not so much. Especially when Mu-jin starts catching glimpses of a ghostly figure: enter Jo Eun-young, a former nurse with unfinished business and a very direct approach. She possesses Mu-jin mid-taxi ride and storms the hospital like a one-woman reckoning.

Mu-jin, fully under her control, confronts Doctor Park, throws his own words back at him, and even lands a slap so hard it sends the good doctor flying. Security boots Mu-jin out, and only then does the possession wear off. Understandably freaked out, Mu-jin, Hee-joo, and Gyeon-woo scramble for help—shamans, priests, monks—you name it. No luck. So they do what they do best: investigate.

Thanks to Bo-sal, Mu-jin relives Eun-young’s tragic past. Overworked and constantly berated by her senior, Nurse Lee, Eun-young was crumbling under pressure. Her breaking point came after a fatal mistake, she administered an IV under Doctor Park’s orders, which caused a patient’s cardiac arrest. Instead of taking responsibility, Park blamed her. She was silenced, isolated, and eventually took her own life.

Worse still, her cries for help went unheard. Her bullying report literally slipped under a cabinet during a confrontation and that detail becomes the key to the truth.

Gyeon-woo dons a doctor’s coat and goes undercover again, managing to flirt his way through the hospital until he’s inevitably busted. A slow-motion chase follows, complete with dramatic rooftop confrontation. Nurse Lee, now ostracized and wracked with guilt, contemplates jumping. But possessed-Mu-jin returns just in time to stop her, and Eun-young finally gets through to her former tormentor.

Nurse Lee confesses. She submits the missing records, proving Doctor Park ordered the IV. The truth explodes. Park spirals into public disgrace and psychiatric treatment, while the hospital faces backlash for its toxic hierarchy and brutal work culture.

With justice served, Eun-young’s spirit finally lets go.

As for Mu-jin? He gets barely a moment of peace. Just when he thinks it’s over, he kneels in the street to tie his shoelace, right as a sleepy bus driver comes barreling toward him.

Looks like Bo-sal’s back on the clock. And Mu-jin? Still very much not off-duty.

DramaZen's Opinion

Episodes 3 and 4 had me hooked.

This show just keeps leveling up. Mu-jin’s job is basically “haunted punching bag,” and somehow it never stops being hilarious and heartbreaking. Nurse Eun-young’s story hit hard. The possession scenes? Chaotic gold. I will never get over Mu-jin getting dragged through a hospital, choking doctors, and yelling at ghosts while Hee-joo piggybacks him like it’s just another Tuesday.

And can we talk about the ghost justice system? It’s brutal! Bo-sal’s contract is straight out of hell—literally. Mu-jin’s stuck doing unpaid overtime for angry spirits with trauma and a grudge, and now every near-death experience is basically a client call.

Still, the show balances the pain with some sharp laughs (Gyeon-woo going undercover again was a disaster, in the best way), and that rooftop scene had me holding my breath. Every episode peels back another layer, and I’m already too invested. Bring on the next ghost—I know Mu-jin’s not getting a break anytime soon.
