Notes from the Last Row Episode 3 continues to turn the mystery around Su-hun, Kang, and the Kim family into something much more complicated. After the shocking accident involving Min-hui, the latest episode focuses on Mun-oh’s growing obsession with Kang’s manuscript and his desperate attempt to understand whether Su-hun is hiding something.
What makes this episode interesting is how the story keeps blurring the line between truth and fiction. Through Kang’s writing, we see events unfold from his perspective, but I found myself questioning how much of it can actually be trusted.
Notes from the Last Row Episode 3 Recap
The episode begins immediately after the accident, with Min-hui being taken to the hospital. Mun-oh watches from a distance and notices something strange: Su-hun is only observing the situation instead of stepping in to help. That moment leaves a strong impression on Mun-oh, especially because it confirms his growing suspicion that something is wrong with his old friend.
Afterward, Mun-oh drives Kang back to the Kim family home. During the trip, Kang apologizes for interfering in Su-hun’s personal life. He also thanks Mun-oh for helping him get home safely. However, their conversation quickly turns serious when Mun-oh confronts Kang about keeping a major secret from him — the fact that Su-hun is Se-yun’s father.
Kang seems genuinely confused by Mun-oh’s reaction. He says he didn’t know Su-hun was a famous novelist and questions why that revelation affects Mun-oh so much. For Kang, it appears to be just another detail about the family, but for Mun-oh, it changes the way he sees everything.
Once Mun-oh returns home, he starts reading Kang’s stories again from a completely different perspective. This time, he imagines Su-hun as Se-yun’s father and Eun-joo as Se-yun’s mother. The manuscript suddenly feels more personal, and Mun-oh begins connecting the fictional events to memories from his own past.
A flashback takes us back to their college years, when Mun-oh first met Eun-joo, the woman he secretly loved. His feelings were never returned, and he remembers watching Eun-joo and Su-hun become a couple. Seeing their relationship through Kang’s writing now clearly affects him.
The emotional impact becomes too much when Mun-oh reaches the parts describing Su-hun and Eun-joo’s relationship. He breaks down while reading, angry that Su-hun cheated on Eun-joo. It becomes clear that Mun-oh’s reaction is not only about the story itself, there are old wounds involved.
Min-hui’s Death Changes Everything for Kang and Mun-oh
During his next class, Mun-oh notices Kang sitting alone in the last row, staring out the window. The usually curious student looks completely defeated. Mun-oh approaches him and asks him to explain what has happened inside the Kim family home since Min-hui’s accident.
Kang gives him devastating news: Min-hui has died.
The revelation changes the mood completely. Mun-oh immediately distances himself from Su-hun, saying that Su-hun was never truly his friend. Kang also speaks negatively about Su-hun, describing him in a way that makes Mun-oh’s existing doubts even stronger.
Before leaving, Kang gives Mun-oh his newest manuscript. He explains that Min-hui’s death has affected him deeply and that he may stop writing for a while.
When Mun-oh reads the new assignment, the story becomes even darker. Kang writes about Su-hun acting strangely calm after Min-hui’s accident while Eun-joo becomes worried because their housekeeper does not show up for work.
Eventually, Eun-joo receives a call from the police informing the family that Min-hui has died.
Se-yun is devastated by the news. He collapses after hearing what happened, and Eun-joo immediately rushes to comfort him. However, Su-hun’s reaction feels cold. Instead of showing concern, he describes Se-yun as overly sensitive.
Later, Kang overhears a private conversation between Su-hun and Eun-joo. Eun-joo blames herself for Min-hui’s death, but Su-hun tries to calm her down. The disturbing part is the expression on his face — Kang describes it as a malicious smile, almost like Su-hun is pleased by what happened.
Reading this part of the manuscript affects Mun-oh deeply. He begins to see Su-hun less as an old friend and more as someone dangerous.
Mun-oh Joins Kang’s Investigation Into Su-hun
After finishing Kang’s assignment, Mun-oh meets him at his workplace to discuss the story. Instead of telling him to stop, Mun-oh encourages Kang to continue writing and uncover what really happened.
Kang points out that Mun-oh may not be the right person to judge the story because he personally knows Su-hun. He believes there is a conflict of interest.
Mun-oh disagrees. He insists that he can separate his personal feelings from his role as a professor helping a young writer. He even asks Kang to hide his identity from Su-hun.
Mun-oh wants answers, but he also wants Kang to investigate deeper. He questions why Kang describes Su-hun as malicious and asks what made him believe Su-hun was involved in Min-hui’s accident.
Instead of accepting the story immediately, Mun-oh tells Kang to find evidence and figure out whether Su-hun really had anything to do with what happened.
Kang later asks Mun-oh to join him at the hotel so they can question people connected to the case. But Mun-oh makes an excuse, saying he has somewhere else to be that evening.
Instead, he takes Hyun-suk to watch a movie. However, he spends most of the time distracted, waiting for Kang to send him updates.
At dinner with Hyung-jong and his wife afterward, Mun-oh can barely focus. He keeps checking his phone, which doesn’t go unnoticed. Hyung-jong’s wife jokes about his behavior and reminds him of a time years ago when he neglected Hyun-suk.
Mun-oh brushes off the comment, but when Kang finally messages him, he immediately leaves the table to read the new assignment.
Hyun-suk misunderstands the situation and assumes Mun-oh is upset because of their friend’s comment.
Kang’s Manuscript Reveals a Disturbing New Lead
The new chapter of Kang’s story reveals his attempt to question hotel employees about Su-hun and Min-hui’s relationship.
Kang writes about reconnecting with Jae-sik, a hotel employee he worked with the previous year. According to Jae-sik, he witnessed the accident and knows more about what happened.
Jae-sik tells Kang that Su-hun often visited the hotel with Min-hui. He also remembers seeing women’s roleplay lingerie inside Su-hun’s hotel room, suggesting that their relationship was more complicated than people knew.
Mun-oh is about to continue reading when Hyung-jong suddenly calls and tells him that Su-hun has arrived at dinner.
The timing immediately creates tension.
Hyun-suk is surprised when she learns about the book convention because Mun-oh never mentioned it to her. When Su-hun arrives, he brings up Eun-joo and says that they still talk about Mun-oh.
Mun-oh pretends not to know anything when Su-hun mentions Se-yun.
Trying to understand what kind of person Su-hun has become, Mun-oh starts asking him about his writing. He questions how Su-hun develops ideas and creates new novels.
The conversation feels less like two old friends talking and more like an interrogation.
Hyun-suk notices the uncomfortable atmosphere. She also mentions that Mun-oh has been struggling to write his second novel because he has no ideas yet.
Notes from the Last Row Episode 3 Review: Can Mun-oh Trust Kang’s Version of the Truth?
Later that night, Mun-oh’s frustration finally explodes. He gets angry at Hyun-suk for embarrassing him in front of Su-hun, but the argument quickly turns into something much deeper.
Hyun-suk questions whether Mun-oh is still holding onto feelings for Eun-joo, his first love. She also wonders if his reaction toward Su-hun comes from jealousy over Su-hun’s success as a writer.
Mun-oh rejects the idea and insists that Su-hun is simply a bad person. He tells Hyun-suk that she doesn’t know Su-hun the way he does.
After the argument, Mun-oh returns to Kang’s manuscript, unable to let go of the story.
The next part of Kang’s writing reveals an even more disturbing detail. According to Jae-sik, on the night of the accident, he heard Min-hui and Su-hun having a violent argument inside the hotel room.
Jae-sik also mentions another important clue: a young boy, around Kang’s age, visited the hotel the day after the accident. The boy asked questions about what happened and seemed determined to find out whether Min-hui had actually been murdered.
Mun-oh becomes completely absorbed in the story. While reading, he falls asleep and dreams about the scene, but the images continue disturbing him even after he wakes up.
Unable to ignore what he has learned, Mun-oh calls Kang in the middle of the night and asks him to check the hotel CCTV footage to identify the boy.
Kang’s answer surprises him. He says he already knows who the boy is.
At the same time, another emotional moment is happening inside the Kim family home. Se-yun destroys Su-hun’s novels in his bedroom, showing how deeply affected he is by everything happening around him.
He then calls his sister, Jeong-hu, and tells her that their father has killed someone.
The episode ends there, leaving the biggest questions unanswered.
My Thoughts on Notes from the Last Row Episode 3
Episode 3 continues to make Notes from the Last Row a frustrating but fascinating mystery. I still don’t think the show wants us to understand everything yet, and honestly, that uncertainty seems intentional.
The biggest problem, and also the biggest strength, is that we still don’t know whether Kang is telling the truth.
Everything we learn comes through his manuscript, which means we are experiencing the story through his interpretation. He could be revealing hidden truths, but he could also be shaping events based on his own emotions and assumptions.
That makes every scene feel suspicious.
Mun-oh is especially interesting because he doesn’t exactly approach Kang’s story objectively. He claims he can separate his feelings from his judgment, but I don’t fully believe that. His history with Su-hun and Eun-joo clearly affects the way he reads the manuscript.
In some ways, Mun-oh wants to believe Kang because Kang’s version of events matches what he already feels about Su-hun.
That’s what makes their dynamic so complicated.
Mun-oh isn’t just investigating Su-hun. He is also dealing with his own unresolved feelings, regrets, and insecurities. His marriage with Hyun-suk feels distant, and the way he reacts whenever Eun-joo or Su-hun comes up suggests that he never fully moved on from the past.
The parallel between the characters is also becoming clearer. Kang seems obsessed with Se-yun and his family situation, while Mun-oh appears to be obsessed with Su-hun’s life and everything he represents.
Both men are chasing something they feel they lost.
The mystery surrounding Su-hun is still the biggest question mark. Is he truly hiding something terrible, or are Kang and Mun-oh simply seeing him through their own biases? The episode gives enough clues to keep the suspicion alive but never enough information to confirm anything.
And that’s probably why this episode works.
I’m still watching Kang’s story carefully because I don’t think we should accept everything he writes as fact. Until the show gives us a clearer picture, every character feels unreliable in their own way.
Episode 3 doesn’t provide answers, but it does make the mystery much deeper. I’m curious to see how this investigation develops and whether the truth about Su-hun is as simple as everyone believes.
