Who Is The Main Character In 'Diary Of A Murderer And Other Stories'?

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 'Notes from Underground' is this fascinating, bitter, and deeply introspective unnamed narrator—often called the Underground Man. He’s this cynical, self-loathing former civil servant who spends the entire novella ranting about society, rationality, and his own contradictions. What’s wild is how Dostoevsky makes you both despise and pity him; he’s like a train wreck you can’ look away from. The other stories in the collection, like 'The Double' or 'White Nights,' have their own protagonists, but none hit quite like the Underground Man. His monologues about free will and suffering feel uncomfortably relatable, even if you’re nothing like him. It’s like peering into a distorted mirror of human nature. I reread it last winter, and it hit differently—maybe because I was in a mood, but his rants about 'conscious inertia' and spite felt weirdly validating. Not that I’d admit that to anyone in real life. The way Dostoevsky captures self-sabotage is almost too real.

Ever since I picked up 'A Killer's Wife', I couldn't put it down—it's one of those thrillers that digs into the psyche of its characters in a way that feels uncomfortably real. The main character is Jessica Yardley, a prosecutor with a dark past that comes crashing back into her life when her ex-husband, a notorious serial killer, becomes active again. What makes Jessica so compelling isn't just her career or her connection to the killer; it's how the story peels back layers of her trauma, resilience, and the moral dilemmas she faces. I love how the author doesn't just make her a victim or a hero—she's flawed, complex, and constantly wrestling with the weight of her history. The way her past intertwines with her present work adds this delicious tension to every chapter. Honestly, I finished the book in two sittings because I needed to know how she'd navigate the chaos.

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.

Watching 'Memoirs of a Murderer' hit me like a slow, cold unraveling—I found myself obsessed with who the story lives inside. The central figure is the narrator: an aging man with a history as a serial killer who’s losing his memory to a degenerative condition. He’s both terrifying and pitiable, unreliable because his recollection is slipping; the whole tension of the story rides on whether he’s truly reformed, whether he remembers his own past correctly, and whether his confessions can be trusted. That voice—half proud, half forgetful—kept me turning pages and rewatching scenes in my head. Around him are a few crucial people who shape the plot. There’s his daughter (or daughter-figure in some adaptations), someone he desperately wants to protect and who humanizes him; her safety becomes the narrator’s main anchor. Then there’s the younger man who insinuates himself into their lives—he’s charming, possibly dangerous, and his ambiguous motives create a poisonous triangle with the narrator and the daughter. Finally, the law or figures of investigation—detectives, reporters, or local community members—float in and out, providing outside pressure and moral contrast. The novel/film turns on memory, guilt, and protection, so these roles feel less like simple archetypes and more like mirrors reflecting what the narrator can or cannot remember. If you like character studies that make you question perspective—where the ‘who’ is as slippery as the truth—this one’s a neat, unsettling ride; I still catch myself thinking about the narrator’s confessions on late-night walks.

That collection hit me like a freight train—in the best way possible. Kim Young-ha’s 'Diary of a Murderer and Other Stories' isn’t just a series of thrillers; it’s a deep dive into the human psyche, wrapped in deceptively simple prose. The title story, about a serial killer with Alzheimer’s, is brutally poetic. I found myself sympathizing with a murderer, which unsettled me for days. The way memory and morality blur in that narrative is masterful. The shorter pieces are just as gripping. 'The Origin of Life' has this eerie, almost surreal vibe that lingers. What I love is how Kim plays with genre—crime, horror, existential drama—all while keeping the focus on characters who feel painfully real. If you enjoy stories that unsettle and provoke, this one’s a gem. It’s the kind of book that makes you stare at the wall afterward, questioning everything.

The diary in 'Diary of a Murderer and Other Stories' feels like a twisted mirror reflecting the killer's psyche. It's not just a record of crimes—it's a desperate attempt to justify the chaos inside their head. I've read plenty of thrillers, but this one stands out because the diary isn't a mere plot device; it's almost a character itself. The murderer uses it to construct a narrative where they're the protagonist, not the villain. It reminds me of how people curate social media to show only what they want others to see, except here, it's a grotesque performance for an audience of one. What fascinates me is how the diary becomes a battleground for truth and delusion. Some entries read like cold case files, while others drip with pathetic self-pity. The contrast exposes how fragile the killer's grip on reality is. Kim Young-ha writes these passages with such clinical precision that you almost sympathize—until the next page snaps you back to horror. The diary's physical presence, with its ink stains and torn edges, makes the character's unraveling disturbingly tactile.
