Oh My Ghost Clients Episode 4 recap: Mu-jin meets Eun-yeong’s parents

At the beginning of episode 4 of Oh My Ghost Clients, Mu-jin explains the laws and scenarios that would be helpful for Eun-yeong’s case, such as a diagnosis of her suffering from depression due to her stressful job. They then go to meet her parents and everyone who had worked on the case.

Her parents told Mu-jin how unhappy she had been in her job, but they couldn’t help her. Later, they found out no law firm was willing to take Eun-yeong’s case, as they all stated there was a lack of evidence that would hold the hospital accountable. Hee-ju tries to get in contact with Eun-yeong’s friend at the hospital, who hides from her.

After meeting everyone, they come back to the office without any successful leads, until Mu-jin remembers the workplace bullying complaint report filed by Eun-yeong.

Oh My Ghost Clients Episode 4 recap: Gyeon-u goes undercover, again

Gyeon-u introduces his new gadget, a set of spectacles which work as a camera as well, in this episode of Oh My Ghost Clients. This new gadget comes in handy when he goes undercover as a doctor in the hospital to bring the report of Eun-yeong, which Mu-jin remembers seeing slip through the shelves in the supply room.

While going around, impressing the nurses with his good looks, he also stumbles upon Seo-jeong, the nurse who bullied Eun-yeong. As Mu-jin notices her through the camera, he quickly enters the hospital premises where he is banned and is quickly noticed by the doctor whom he had beaten the last time.

The doctor informs the security, and Mu-jin finds himself running away from getting caught again. On the other hand, Gyeon-u’s ruse is also caught as one of the nurses finds out that he doesn’t work in the hospital, prompting him to make a run as well. They both later meet at the emergency exit and run toward the rooftop of the building, as the security officials follow them from the other end.

Oh My Ghost Clients Episode 4 recap: Mu-jin and Gyeon-u save Seo-jeong and also obtain the evidence to help Eun-yeong

As they find themselves on the rooftop and inform Hee-ju about it, they notice someone standing at the edge of the rooftop. As they run toward her, Mu-jin notices that it's Seo-jeong. He tries to convince her not to jump, but her foot trips, and she almost falls until Mu-jin grabs her hand.

As Mu-jin asks her not to leave his hand, Seo-jeong sees glimpses of Eun-yeong on his face. She apologizes to Eun-yeong and is told by Eun-yeong to help her out if she feels sorry. Seo-jeong is saved by Mu-jin and Gyeon-u from falling.

Gyeon-u later shows them the complaint form filled by Eun-yeong that he found in the supply room, based on which they could file a complaint now, which Gyeon-u live streams on his YouTube channel, which becomes one of the trending videos on the internet.

Eun-yeong’s friend also comes forward and narrates the incident surrounding Eun-yeong’s s*icide, helping her case further. But the breakthrough evidence comes from Seo-jeong, who still had preserved the note which proved that the Doctor prescribed the medicine and not Eun-yeong.
