Who Are Main Characters In Memoirs Of A Murderer?

If you’ve ever watched the movie and felt a chill thinking it might be real, you’re not alone — the film is written and shot to feel uncomfortably plausible. Still, no: 'Memoir of a Murderer' (the 2017 Korean film) is not based on a true story. It’s adapted from a 2013 novel by Kim Young-ha, often translated as 'Murderer's Memory' or rendered in English-language listings as 'Memoir of a Murderer'. The movie was directed by Won Shin-yun and stars Sol Kyung-gu and Kim Nam-gil, and both book and film are fictional psychological thrillers that explore memory, guilt, and the horror of losing yourself to dementia. I watched the film late one night and then picked up the novel because I was curious how the narrator’s interior life from the book translated to the screen. The novel leans hard into the unreliable narrator — first-person internal monologue, fragmented memories — whereas the film externalizes that confusion with visual tricks, flashbacks, and a tight focus on the protagonist’s deteriorating mind. People sometimes assume it’s true because the depiction of Alzheimer’s and the moral grayness of the protagonist feel raw and lived-in, but that authenticity is the strength of the writer’s imagination, not a report of actual events. If you like context, it helps to think of 'Memoir of a Murderer' alongside films like 'Memento' or dark Korean thrillers such as 'I Saw the Devil' — they all toy with memory, revenge, and moral ambiguity. The biggest takeaway is that the core story (a former killer with Alzheimer’s suspecting a copycat and struggling to remember) is fictional. That said, the themes are grounded in real human experience — memory loss, the regret of past sins, the fear of losing identity — which is why it hits so hard for many viewers. For a fuller experience, read Kim Young-ha’s book after watching the film: the book’s voice gives you richer internal detail and slightly different beats, while the movie sharpens the suspense with a handful of changed scenes and a more cinematic ending. I still find myself thinking about certain images weeks later, so whether you watch or read first, be ready for a story that lingers in a very human way.

I still get a chill thinking about the way 'Memoirs of a Murderer' plays with memory — it’s like someone handed me a jigsaw puzzle with half the pieces blurred and asked me to trust the picture I’m building. For me, the central theme is memory itself: not just as a plot device (the unreliable recall, the creeping gaps) but as a moral battleground. The narrator’s mind becomes the stage for truth and self-deception, and the book forces you to ask whether a life narrated by a failing memory can be trusted. I read parts of it late at night on the bus, under the warm yellow of the reading lamp, and the fragmented sentences felt like someone whispering confessions through fogged glass. Beyond memory, the book dives deep into moral ambiguity and the slipperiness of conscience. The protagonist isn’t a cartoon villain; they’re human in a way that makes me squirm — capable of reflection, guilt, and self-justification at once. That creates a tension between empathy and revulsion. You find yourself rationalizing their thoughts while recoiling from their actions, which is exactly the unsettling effect the author aims for. Another theme that hooked me was identity: who are we when our past is unreliable? When names, faces, and motives blur, identity becomes less about facts and more about the stories we tell ourselves to keep living. There are other layers worth lingering on. Justice versus revenge turns up often — the book questions formal justice systems while exploring personal retribution and its corrosive cost. Aging and decline, especially when memory slips, are treated with quiet cruelty; the physical and mental deterioration strip away social masks and force raw honesty. The narrative style itself is a theme: confession as catharsis, the intimacy of first-person narration, and the artful use of gaps to make the reader complicit. If you like cross-references, you’ll see echoes of works that play with unreliable narrators and moral complexity, like 'Confessions' or certain noir memoirs, where truth is less a fact and more an argument. Reading it felt like having a dark conversation with someone I both pitied and feared, and that lingering discomfort is exactly why the book kept my thoughts occupied for days.

In 'Memoir of a Murderer', the key themes revolve around guilt, memory, and redemption. The protagonist, a former serial killer with Alzheimer’s, struggles to piece together his past while trying to protect his daughter from a new killer. The narrative delves into the fragility of memory, questioning whether forgetting one’s sins can be a form of absolution or a curse. The tension between his violent past and his desire for a peaceful present creates a haunting exploration of identity and morality. The memoir also examines the nature of evil, blurring the lines between perpetrator and victim. As the protagonist’s memories fade, so does his certainty about his own actions, forcing readers to confront uncomfortable questions about justice and forgiveness. The relationship with his daughter adds a layer of emotional depth, highlighting the possibility of change and the enduring impact of love. The story is a gripping meditation on the human capacity for both destruction and redemption.

I still get a little thrill when someone asks about 'Memoirs of a Murderer'—that book stuck with me for a while. To the point: there isn’t an official sequel to the novel itself. The story as written stands alone; the book was crafted as a self-contained psychological ride, and the author didn’t follow it up with a direct continuation of the same protagonist or plotline. If you’ve read a translation or saw recommendations online, you might notice the title varies slightly in English (sometimes rendered as 'Memoir of a Murderer' or 'The Murderer’s Memory'), and that can make searching for follow-ups confusing. What keeps things interesting is that the novel inspired other media. The best-known spin is the 2017 film adaptation, 'Memoir of a Murderer', which took the core premise and characters and adapted them for the screen. Films can feel like sequels or alternate takes if they add scenes or rearrange events, but that’s adaptation rather than a textual sequel. Also, the book’s author has written a number of other novels exploring similar moral gray areas, memory, and identity—if you liked the tone and themes, I'd recommend looking up his other work such as 'I Have the Right to Destroy Myself' and 'The Plotters' (both of which probe dark inner worlds in different registers). If you’re hunting for more to read, try tracking down translations and the author’s bibliography via the publisher or library catalogs. Sometimes authors publish short stories, magazine pieces, or one-off novellas that revisit settings or motifs without being formal sequels. Fan fiction and discussion forums also sometimes treat the characters as if there were sequels, but that’s unofficial. So, in short: no canonical sequel to the novel itself, but there are adaptations and plenty of similarly flavored reads to chase if you want to keep riding that uneasy, clever-creepy vibe. Personally, when a standalone hits me like that, I end up rereading and then hunting the author’s backlist—it's like meeting a musician whose albums you binge next.

In 'Memoir of a Murderer', the main suspects revolve around a retired serial killer named Kim Byeong-su, who is now suffering from Alzheimer’s. The story takes a twist when he starts suspecting a local taxi driver, Tae-joo, of being a new serial killer. Kim’s fragmented memories and paranoia make him question his own past actions while trying to piece together the truth about Tae-joo. The tension builds as Kim’s daughter, Eun-hee, becomes a potential target, adding a personal stake to his investigation. The narrative cleverly blurs the lines between victim and perpetrator, making it hard to trust anyone, including Kim himself. The film adaptation of this novel amplifies these suspicions with its gritty visuals and haunting performances, leaving viewers guessing until the very end.

I've been meaning to tell anyone who asks that the novel 'Memoirs of a Murderer' was originally written by the Korean novelist Kim Young-ha. The book's Korean title is '살인자의 기억법', and it first appeared in 2013. I picked up a copy after seeing talk about the movie adaptation, and the way Kim Young-ha constructs his unreliable narrator — an aging man struggling with memory loss while wrestling with a dark past — is the thing that hooked me. It reads like a meditation on identity as much as a crime story, and that tonal blend is very Kim Young-ha: edgy, introspective, and a little bit unnerving in the best way. What I love about pointing people to Kim Young-ha is that he's not a one-note writer. If you've read 'I Have the Right to Destroy Myself' or 'The Plotters', you can see how he likes to play with moral ambiguity and philosophical questions, and 'Memoirs of a Murderer' fits neatly into that orbit. The story was later adapted into a 2017 South Korean film of the same name, which brought more mainstream attention to the novel. For readers who enjoy slow-burn psychological thrillers with a twist, the book offers a lot: unreliable memories, the creeping horror of losing oneself, and the ethical puzzles that surface when you can't trust your own recollection. If you're tracking translations, adaptations, or want to compare pages to screen, this novel is a fun study because it plays differently depending on your medium. I remember reading certain passages aloud to a friend on a rainy weekend and getting chills from how intimately the narrator confesses things he may not even fully remember. So, yes: Kim Young-ha wrote the original novel, and if you're in the mood for a heavy, character-driven read that doubles as a mystery, his voice in 'Memoirs of a Murderer' is exactly the kind of literary thrill I keep recommending to people in my book club and to friends who swear they don't read 'serious' fiction.

The main character in 'Diary of a Murderer and Other Stories' shifts depending on which story you're reading, but the standout for me is Byeongsu from the titular novella. He's a former serial killer grappling with dementia, and the way his mind unravels while he tries to protect his adopted daughter is both chilling and heartbreaking. The unreliable narration makes you question everything—is he really being stalked by another killer, or is his fractured memory playing tricks? Kim Young-ha writes psychological tension like no one else, and Byeongsu's twisted paternal love lingers long after the last page. What fascinated me most was how the story weaponizes perspective. We're trapped inside Byeongsu's deteriorating mind, where even mundane details like misplaced keys become ominous. It reminded me of 'The Good Son' meets 'Memento,' but with that uniquely Korean noir flavor. The other stories feature equally compelling protagonists—a grieving father in 'The Origin of Life,' a disaffected youth in 'The Writer'—but Byeongsu's tragedy feels like the collection's dark, pulsing heart.
