Oh My Ghost Clients Episode 5 recap: The trio meets the officials at the University

In episode 5 of Oh My Ghost Clients, Mu-jin meets Hui-ju and Gyeon-u to discuss the case, where he tells them that the University officials are doing this to humiliate them and want them to quit their jobs rather than firing them. It is their way of avoiding public scrutiny of firing older citizens from their jobs.

They then go to meet the man who takes the tests. He tells them that Yeong-sook died as she was already not well. She had ongoing health problems. As Mu-jin confronts him about the tests, the manager tells him that the tests are just part of their job training, and even the custodians are happy, as this makes them more educated and cultured as they work in a top University.

After his denial about the tests being difficult and to humiliate the custodians, Mu-jin and his companions talk to the custodians to find out more about their job difficulties and also the tests. Mu-jin later invites all of them for a treat and talks to them about their work, and tells them that whatever they are going through is not right, and they have a right to speak and can also refuse to appear for the tests. But some of them are happy doing what they do and don’t want to get involved to hamper their jobs, but Mu-jin’s mother stands up to talk about their unfair treatment and how the University looks down on them.

She tells them that they need to be treated better, as they are not ashamed of their work. Her speech encourages her co-workers, and they decide to go with Mu-jin’s plan to protest outside the University to get rid of the tests that they have to take.

At the end of this episode of Oh My Ghost Clients, the trio and the custodians protest outside the University, which provokes the officials to call the police, and even threaten them to fire them from their jobs. The police come and try to take Mu-jin with them while Hui-joo records everything. While the case doesn’t look easier this time, Mu-jin is determined to help his mother, Yeong-suk, and their co-workers from living a life where they are humiliated almost every day.
