The fifth episode of Teach You A Lesson is one of the most heart-wrenching and emotionally exhausting chapters of the series to date. The story throws light on the immense pressure teachers face when parental complaints snowball to that extent and how relentless emotional abuse can push one to the brink.
The episode begins with a shocking moment as first-grade teacher Choi Ji-seon (played by Han Ji-min) tries to take her own life inside the playroom she created for her students. She sends one last message to her mother asking to read her diary before she tries it. Fortunately, Han-rim gets there in time and makes sure Ji-seon gets help immediately.
After taking a psychological test, doctors decide that Ji-seon is suffering from dangerously high levels of stress. Han-rim insists that she take a break from teaching and concentrate on her recovery before the situation becomes even more tragic.
Ji-seon begins to receive treatment and Hwa-jin takes her place in class. What begins as a routine assignment soon becomes a lesson in the everyday struggles that teachers face. Hwa-jin is finding it a lot harder to manage the students than she imagined and feels the pressure Ji-seon was under.
The episode then flashes back to the start of Ji-seon’s nightmare.
When Ji-seon arrived at Hyeongjung Elementary School, U-jin’s mom approached her, clearly concerned about her son’s confidence and how he fits in. Initially, the calls for assistance seemed reasonable. But over time the relationship crossed the line of professional boundaries.
The mother began to call Ji-seon at all hours of the day and night. Her messages became increasingly insistent and she began to keep track of the teacher’s social media activity, even commenting on aspects of her personal life that had nothing to do with school.
Ji-seon tells the principal about the harassment, but she is not supported. The administration suggests that instead of talking to the parent, she ignore the behavior to avoid conflict.
With mounting pressure, Ji-seon’s determined to help U-jin and makes him a special playroom where he can feel comfortable expressing himself. She works hard and the little boy slowly starts to make friends with his classmates.
Unfortunately, an incident at school shatters that progress. If U-jin is bumped by another kid by accident, he retaliates with physical aggression. What should have been a straightforward disciplinary problem becomes a confrontation between parents.
Things only get worse when U-jin’s mother starts to blame Ji-seon for her son’s emotional problems. Her complaints escalate and escalate and escalate until they are accusations of misconduct. The accusations become more bizarre, with the teacher being accused of sexual misconduct.
The after-effects are disastrous for Ji-seon.
As investigations begin, U-jin’s father aggressively comes at her at school, while his wife takes the campaign a step further by posting Ji-seon’s personal phone number online. The teacher is deluged with phone calls, harassment and public scrutiny.
Ji-seon feels abandoned by the system, and the constant attacks get to be too much for her, until she reaches a breaking point. The emotional weight becomes too much and she attempts to commit suicide.
In the present, Hwa-jin, Han-rim and the rest of the ERPB team talk about the bigger issue facing educators. “Emotional abuse is hard to prove,” says Gang-seok, which leaves victims with no meaningful protection and suffering. Hwa-jin agreed, saying current regulations do not go far enough to protect teachers from hostile parents.
Hwa-jin, unwilling to let Ji-seon’s pain go unanswered, begins his own investigation.
But instead of confronting U-jin’s mother directly, he chooses a different path. He praises her and her son, initially lowering her defenses, then turning her own tactics against her. Hwa-jin starts to hassle her with questions and concerns all the time, the same way she used to hassle Ji-seon.
The strategy soon frustrates her.
She tries to get her husband to fight, but Hwa-jin visits him at work and exposes his aggressive behavior in public. The encounter leaves little doubt that intimidation tactics will no longer work on the inspector of the ERPB.
At the same time, a major change is taking place in the school administration. In the end, the principal must confront her failings, acknowledging that she was more concerned with avoiding complaints than protecting one of her teachers. Perhaps for the first time she admits openly the human toll of her choices.
Things get more complicated when U-jin’s mother gets other parents to support her case. In stead, the meeting goes spectacularly wrong. Hwa-jin comes with proof that U-jin himself might be suffering from emotional abuse at home. With the release of more information, the other parents begin to criticize her treatment of Ji-seon rather than support her campaign.
But her struggle to push back gets harder when she learns Hwa-jin is an ERPB inspector. Now the woman who spent months filing complaints is herself under investigation.
U-jin gets one of the most touching moments in the episode as the adults keep fighting. The young boy reaches out his hand to Ji-seon and sincerely apologizes for everything that she has been through because of his mother’s actions. He mentions the anger and pressure he’s under at home during their discussion.
But Ji-seon does not resent him, and in fact comforts him, telling him that none of this is his fault. It is a scene which reminds us that children are often caught in the middle of conflicts created by adults.
By the end of the episode, authorities officially investigate U-jin’s mother for the emotional damage she caused Ji-seon. Meanwhile, Gang-seok tells the media he will provide stronger protections and mental health support for teachers in similar situations.
The episode ends on a powerful note of accountability as Gang-seok officially apologizes to the educators for the Ministry of Education’s past failures. Meanwhile, Hwa-jin finally reads Ga-yun’s diary and finds information that could reveal Gyu-cheol’s involvement in the troubles that haunted her before her death.## Review
Episode 5 is easily one of the most emotionally powerful installments of Teach You A Lesson so far. Instead of physical violence and bullying, the show opts for another kind of abuse that is often overlooked, the mental torture that teachers suffer from entitled and obsessive parents.
It’s genuinely uncomfortable to watch Ji-seon’s ordeal unfold and that’s exactly why the episode is so effective. The endless messages, false accusations, public harassment and lack of institutional support make a realistic portrait of how emotional abuse slowly destroys a person’s mental health.
The writers deserve credit for not reducing the situation to a simple hero versus villain conflict. U-jin’s mother is clearly doing tremendous damage, but the episode also shows how systemic failures allow the situation to spiral out of control.
Ji-seon and U-jin have the best moments. Despite everything that has happened, their relationship is still sincere and compassionate, and their reunion is one of the most emotional moments of the episode.
The final few scenes continue to add intrigue to the mystery of Ga-yun’s death and Gyu-cheol’s involvement, setting up what could become one of the series’ most important storylines moving forward.
One of the show’s most affecting chapters to date, episode 5 is a blend of emotional storytelling, timely social commentary and strong character work.
