| The Perfect Lie Episode 4 recap and review. |
The fourth episode of The Perfect Lie takes the complicated case between Ji-seon and Jun-ho into even murkier territory, with conflicting accounts, questionable evidence and a polygraph test that threatens to change how everyone sees the situation. While Jun-ho insists their encounter was consensual, Ji-seon remains convinced that something happened against her wishes. Unfortunately, the investigation is proving far less straightforward than either side might have expected, and the people caught in the middle are beginning to pay the price.
Episode 4 opens with Ji-seon replaying the kiss she shared with Jun-ho on her couch. Although she remembers the moment, she firmly maintains that kissing him did not mean she had agreed to anything that followed. Meanwhile, Jun-ho gives investigators a detailed account of the evening, explaining how their interaction developed after they started drinking wine. According to him, the atmosphere gradually became more relaxed, Ji-seon initiated the kiss and eventually led him into her bedroom.
Jun-ho claims that she never asked him to stop and insists that he believed they had both enjoyed the evening. He even points out that he checked on her the following morning and sent her some porridge. Ji-seon, however, tells a completely different story, maintaining that she repeatedly asked him to stop. With two people describing the same evening in entirely different ways, investigators have a difficult job ahead.
At the police station, Chan-soo visits Jun-ho and offers to represent him as his lawyer. He advises him to prepare for the worst while making sure the truth is properly protected. It is not exactly the sort of conversation anyone wants to have after a night in police custody, but Jun-ho is going to need all the help he can get.
Meanwhile, Ji-eun takes Ji-seon to her home so she can spend the night somewhere comfortable. She initially tells Hyung-soo that Ji-seon is unwell, avoiding the uncomfortable explanation of what has happened. However, she eventually tells him the truth the following day. Later, Ji-eun offers to return to Ji-seon's house to collect some belongings for her. On the way, she receives a phone call but quickly ignores it, leaving another little detail hanging in the background.
At school, So-yeon starts wondering whether Hyun-soo has feelings for her. Her suspicions come from his earlier lie about the shoe incident and the gift he subsequently gave her. Hyun-soo denies everything, although his increasingly red face does a rather poor job of supporting his argument. Sometimes, the truth is written all over someone's face, even when they are determined to deny it.
Jun-ho spends the night in remand before being released after Ji-seon's toxicology results arrive. The report finds no trace of drugs in her system, apart from alcohol. With no immediate evidence supporting the possibility of drugging, the investigation becomes even more complicated. Jun-ho returns home and tells Hyun-soo that he has been busy at the hospital, keeping the real reason for his absence from his son.
Ji-seon, meanwhile, wakes from a nightmare and decides to return to work. Her supervisor is far from impressed, reprimanding her for missing the previous day and allowing Ji-eun to contact the school on her behalf. Things become even more uncomfortable when Ji-seon starts treating Hyun-soo coldly, creating distance between herself and the boy without explaining why.
That tension soon spills into the school corridors. Shortly after class, Hyun-soo gets into a serious fight with one of his bullies. The boys make insulting remarks about Jun-ho and accuse him of being a sex offender, which pushes Hyun-soo beyond his limits. Teachers, including Ji-seon, quickly intervene to separate them.
The confrontation appears to trigger something in Ji-seon. Once she returns home, she tries to piece together the missing details of that evening, hoping to recover memories that remain frustratingly unclear. Just as she is struggling with this, investigators Jang Du-il and Hwa-young arrive to ask more questions.
Jang Du-il begins by asking how Ji-seon manages to pay for her house. Naturally, she questions why her finances have anything to do with the investigation. The officers then explain that Jun-ho has been released while their enquiries continue. They also point out that the available evidence does not support her account particularly well.
Restaurant CCTV footage and witness statements suggest that Ji-seon and Jun-ho appeared comfortable with each other during their evening together. This contradicts parts of her statement, leaving investigators uncertain about what actually happened. Ji-seon becomes increasingly frustrated and demands to know why nobody believes her. She explains that she can barely remember anything after inviting Jun-ho inside, but her account remains difficult to reconcile with the evidence.
After the officers leave, Ji-seon begins thinking about the wine glasses from that evening. She calls Ji-eun to ask whether she was the one who washed them, before breaking down in tears. She starts wondering whether Jun-ho might have put something in her drink.
Determined to find an explanation, Ji-seon researches cases involving drug-facilitated assaults. She comes across information about GHB and begins considering whether Jun-ho could have used it, particularly because the substance can become difficult to detect after a relatively short period. However, the absence of supporting toxicology evidence leaves her theory uncertain.
Ji-eun challenges the gaps in Ji-seon's explanation, which only makes her more defensive. The conversation becomes increasingly tense as Ji-seon revisits her memories of drinking wine with Jun-ho while looking through a photo album. The more she tries to remember, the less certain she seems about what happened.
Later that evening, Jun-ho visits Ji-seon and asks why she is making claims about their encounter that he believes are untrue. He explains that he genuinely liked her and had imagined building a future together. However, as their conversation continues, he realises something important: Ji-seon is genuinely frightened of him and believes he hurt her.
The discovery clearly affects him, but the situation has already moved beyond a private disagreement. Ji-seon heads straight to the police station, hoping to get some answers about her case. Instead, she learns that the investigation will not be forwarded to the prosecution because the police believe there is insufficient evidence against Jun-ho.
Ji-seon loses her temper with Hwa-young, accusing the officers of being careless and failing to take her account seriously. Their disagreement escalates, with Ji-seon making it clear that she has no intention of accepting the decision quietly. She eventually leaves after a heated confrontation.
Seeking another possible explanation, Ji-seon meets Jung-yeon, who brings up information about Jun-ho's late wife. Apparently, she struggled with depression and died after an overdose. This raises questions about whether Jun-ho might have played a role in her death, although there is no established evidence connecting him to it.
Ji-seon refuses to use his late wife's death as a way of strengthening her own case. It is an important distinction, particularly when the investigation is already surrounded by uncertainty. She wants answers about her experience, not another tragedy to become part of the argument.
At home, Jun-ho finally decides to tell Hyun-soo that something serious has happened. He reassures his son and asks him to trust him, just as he did during the earlier shoe incident. However, he deliberately avoids revealing that Ji-seon is the woman making the accusations.
Instead, Jun-ho encourages Hyun-soo to keep his head up because he believes he has done nothing wrong. Unfortunately, maintaining that confidence becomes increasingly difficult when the consequences start affecting his professional life.
Despite the police deciding not to send the case to the prosecution, the hospital continues to distance itself from Jun-ho. His colleagues gossip about the situation, while others seem almost entertained by the collapse of his previously spotless reputation. Apparently, being known as Mr Perfect comes with a particularly unpleasant downside when that image starts falling apart.
The hospital director eventually removes Jun-ho from surgery and replaces him with Ji-eun. He asks her to pass on an apology to Ji-seon, explaining that he is sorry about the misunderstanding and maintaining that he did not hurt her. The decision adds another uncomfortable layer to an already complicated situation, especially with Ji-eun now caught between the two sides.
Hwa-young later visits Ji-seon and apologises for how the investigation has developed. She admits that she is struggling to determine which account is truthful. Rather than continuing to go around in circles, she suggests a polygraph test to help clarify the situation. Ji-seon agrees, seemingly confident that the results will support her version of events.
Hwa-young then approaches Jun-ho with the same proposal. He initially hesitates, understandably aware that the test could have serious consequences for his reputation. However, he eventually agrees because he wants to establish his innocence and put the entire situation behind him. He also knows that Ji-seon is still his son's teacher, making it difficult to simply walk away from the situation.
The polygraph sessions reveal some surprisingly personal details about both individuals. Ji-seon discloses that several boys from her neighbourhood sexually assaulted her when she was in middle school. The revelation offers some insight into her past, although it does not automatically explain the events surrounding her encounter with Jun-ho.
Jun-ho, meanwhile, becomes emotional while recalling the death of a stray cat when he was nine years old. It is an unexpectedly personal moment, showing a side of him that has little to do with the confident doctor everyone knows.
However, the results deliver a significant development. Jun-ho's responses indicate that he is telling the truth, while Ji-seon's results show signs of deception. Hwa-young visits Ji-seon to discuss the findings, but she is furious and struggles to understand how the test could produce such an outcome.
As if the situation could not become more complicated, Chan-soo arrives at Jun-ho's home with another troubling revelation. He claims that Ji-seon has previously accused another man of rape, pursued the case for an extended period, damaged his reputation and eventually accepted a substantial financial settlement.
Jun-ho refuses to accept the allegation immediately, believing there could be a misunderstanding. Chan-soo, however, is convinced that his client needs to take the matter seriously. He once again encourages Jun-ho to appoint him as his lawyer and prepare to take legal action against Ji-seon.
The episode closes with Jun-ho facing a difficult decision. He has already lost his position in the operating theatre, his professional reputation is suffering and his son is struggling with the rumours surrounding their family. Now, Chan-soo wants him to fight back legally. Whether Jun-ho is prepared to take that step could become another major turning point in the story.
The Perfect Lie Episode 4 Review
Episode 4 is arguably one of the more frustrating yet interesting instalments of The Perfect Lie so far. The series does a decent job of keeping viewers caught between two conflicting accounts without making the investigation feel like a straightforward mystery with an obvious answer. Ji-seon's missing memories and Jun-ho's detailed explanation create an uncomfortable contrast, while the police investigation adds another layer of uncertainty. The polygraph results are particularly interesting because they appear to settle the argument, but they also raise questions about how much viewers should trust the information presented.
Jun-ho's professional downfall is another strong part of the episode, showing how quickly public opinion can change when someone's reputation becomes the subject of gossip. Meanwhile, Hyun-soo remains caught in a situation he never asked for. The only drawback is that some confrontations feel repetitive, with characters spending considerable time arguing without moving the investigation forward. Still, the final revelation from Chan-soo provides enough intrigue to keep the story moving.
Overall, The Perfect Lie Episode 4 delivers a tense instalment built around unreliable memories, damaged reputations and an investigation that refuses to offer easy answers. The polygraph results might appear decisive, but Chan-soo's latest revelation suggests there is considerably more to Ji-seon's past than viewers have been told. Is Jun-ho genuinely innocent, or is the series preparing another unexpected turn? And what exactly is Ji-seon struggling to remember? Share your thoughts on the episode and whether you believe the investigation has reached the right conclusion.
