Korean dramas usually follow a pretty predictable rhythm. You’ve got your sweeping romances, your historical epics with fancy hats, and your gritty police procedurals where everyone is perpetually exhausted. But then The Killer’s Shopping List showed up on tvN and basically threw the rulebook out the window. It’s weird. It’s funny. It’s deeply uncomfortable at times.
Lee Kwang-soo plays Ahn Dae-sung, a guy who is functionally a genius but has spent years failing the civil service exam. He’s stuck working at his mom’s grocery store, MS Mart. He’s observant—maybe too observant. When a body turns up in their neighborhood, the only real clues are the items bought at the store.
That’s the hook.
It’s not just a whodunnit. It’s a "who bought this specific brand of stockings and some glue" kind of mystery. Honestly, the show captures that specific brand of suburban paranoia where you realize you don’t actually know the people you see every single day at the checkout counter.
Why the MS Mart Setting Actually Matters
Most thrillers want to take you to dark alleys or high-tech forensic labs. The Killer’s Shopping List stays in the aisles of a discount mart. Why? Because the grocery store is the heartbeat of a community. It’s where people reveal their secrets through their habits.
Think about it.
Your grocer knows if you’re depressed because you stopped buying fresh veg and started buying frozen dinners. They know if you’re having an affair. They know if you’re struggling with money. In this show, the shopping receipt becomes a psychological profile. When a murder happens near the mart, Dae-sung realizes that the mundane objects he scans every day—bottled water, trash bags, specific snacks—are actually pieces of a puzzle.

The drama, which aired in 2022 and consists of a tight eight episodes, managed to avoid the "filler" problem that plagues 16-episode series. It moves fast. It’s based on a novel by Kang Ji-young, and you can feel that literary DNA in the way the characters are fleshed out. They aren't just suspects; they’re neighbors with messy lives.
Lee Kwang-soo and the Art of the Loser Hero
Lee Kwang-soo is mostly known for his variety show antics on Running Man, but he’s a genuinely gifted character actor. In The Killer’s Shopping List, he plays Dae-sung with this frantic, anxious energy that makes total sense for a guy who has been labeled a failure for a decade. He has a photographic memory, which is a blessing and a curse.
He notices things.
A kid buying too many snacks. An old man who always buys the same brand of milk. A woman who seems scared of her own shadow. When the police—including his girlfriend Do Ah-hee, played by Seolhyun—dismiss the weirdness of the neighborhood, Dae-sung can’t let it go. He’s basically a grocery store Sherlock Holmes, but with more social awkwardness and less confidence.
Seolhyun’s performance is also worth noting here. Usually, the "girlfriend" role in these shows is just there to be a love interest. Here, she’s a literal police officer who is way better at her job than the people around her, but she’s constantly torn between her professional duty and her boyfriend’s borderline-obsessive amateur sleuthing.
The Dark Side of Suburban Life
The show tackles some pretty heavy themes under its quirky exterior. We’re talking about child abuse, dementia, and the isolation of the elderly. It’s not all jokes.

One of the most chilling aspects of The Killer’s Shopping List is how it portrays the "normal" people. The show asks a very uncomfortable question: How much do we actually care about our neighbors? We see them at the mart. We nod. We move on. But when someone goes missing or starts acting strange, most people look the other way because they don't want the "hassle."
Dae-sung is the only one who cares, and because he cares, he looks like a creep.
There’s a specific subplot involving a young girl named Yul. She’s often left alone, wandering the mart. The way the show handles her story—and how it connects to the central mystery—is heartbreaking. It’s a reminder that sometimes the most dangerous things are happening in broad daylight, right in front of the "Special Offer" bins.
Breaking Down the Mystery Mechanics
The writing is clever because it uses red herrings that feel organic to the setting. For example, a customer buying a huge amount of plastic wrap isn’t necessarily a killer; they could just be moving house. But in the context of a murder, every purchase looks suspicious.
The show uses the receipt as a narrative device.
- Item A: A toy.
- Item B: A specific brand of chocolate.
- Item C: High-end cosmetics.
When these items start appearing at crime scenes, the investigation becomes a race to find the customer ID associated with them. It’s a modern, digital-age twist on classic detective work. We leave digital footprints everywhere, especially at our local grocery store.

Realism vs. K-Drama Tropes
Is it realistic? Kinda.
The police work is a bit exaggerated for dramatic effect, and some of the neighbors are definitely "characters" in the theatrical sense. But the core of the story—the idea that our consumption habits define us—is 100% grounded in reality. Data brokers literally sell our "shopping lists" to companies to predict our behavior. In this show, a serial killer is just another data point that needs to be analyzed.
The cinematography also helps. It uses bright, fluorescent mart lighting to create a sense of unease. Usually, bright light means safety. Here, it’s clinical and exposing. Everything is on display, including the secrets people try to hide in their carts.
Critical Reception and Why You Should Care
When it first aired, critics praised the show for its tone. It’s hard to balance black comedy with a serial killer plot, but director Lee Eon-hee managed to pull it off. It feels similar to films like Memories of Murder but with a distinct, small-town TV energy.
It didn’t pull massive ratings compared to something like Crash Landing on You, but it developed a cult following. People who liked Beyond Evil or The Guest usually find themselves gravitating toward this one because it’s "off-beat." It’s a show for people who are tired of the same three plots being recycled every season.
Actionable Insights for Mystery Fans
If you're planning to watch The Killer’s Shopping List—or if you’ve seen it and want to dive deeper into the genre—here are a few things to keep in mind:
- Watch the background. This is a show where the props actually matter. The items on the shelves in episode one often pay off in episode six. Pay attention to what the background characters are putting in their baskets.
- Don't expect a standard romance. While Dae-sung and Ah-hee are a couple, the show isn't about their "will-they-won't-they." It's about how a crisis tests a long-term relationship.
- Look into the source material. The novella by Kang Ji-young is much darker. If you found the show a bit too "zany," the book provides a more cynical look at the same story.
- Check out "The Killer’s Shopping Mall." If you liked the "ordinary person in extraordinary circumstances" vibe, this 2024 spin-off/companion series (starring Lee Dong-wook) takes the concept and dials the action up to eleven. It's more of an action-thriller, but the thematic connection is there.
- Think about your own "list." Next time you go to the store, look at your receipt. If someone had to figure out who you were based only on those items, what would they think? It’s a fascinating exercise in self-perception.
The Killer’s Shopping List succeeds because it takes the most boring place on earth—a neighborhood grocery store—and turns it into a site of high-stakes tension. It proves that you don't need a massive budget or a global conspiracy to tell a compelling story. Sometimes, all you need is a sharp eye and a very weird shopping cart.
