WARNING: I hope you’ve already seen this show and know what the deal is. But in case you don’t, I felt like I should add in a little warning. This show has mentions of suicide and death (incl. the death of a child). And since this is a review, I do also talk about this (in relation to the show only). Please be aware of that before you continue and be mindful of it. Stay safe ❤️
Simple Description
The Frog centres around the Korean proverb, “A frog dies from a stone thrown inadvertently”—a warning that even the smallest, careless actions can spark irreversible damage. In this case, two seemingly isolated killings wreak havoc on the lives of two men just trying to exist quietly.
⚠️Length Note: This post includes a detailed (and long) story breakdown. Want to skip straight to the review? Jump to the Review
The story opens with Jeon Yeong Ha drowning a woman in a pool. Casual start. We’re then introduced to Yoon Bo Min, a police officer returning to town after 20 years away, and Sang Jun, a third key character who ran a vacation rental back in 2001 called Lake View Motel; a place he was extremely proud of.
We jump back to the present, where Yeong Ha is showing his rental home to a woman named Seong A and her young son. Meanwhile, back in 2001 (there’s a lot of this back-and-forth, so buckle up), Sang Jun welcomes a guest to room 403. That same day, Bo Min, who was just a junior officer at the time, answers a call from Sang Jun’s partner, Eun Gyeong. Something’s not right. The police rush to the motel where they find a dismembered body. Turns out the guest Sang Jun had been so welcoming to was a serial killer named Hyang Cheol. Room 403 was his crime scene.
Fast-forward again: after Seong A checks out, Yeong Ha finds an envelope full of cash and a room key. Everything seems normal until he discovers blood smeared on his record player. A quick flashback reveals Seong A, soaked in blood, calmly playing a record before leaving. Whose blood was it?
Back in 2001, the motel is now infamous, nicknamed the “Murder Motel.” Bookings tank, and after six brutal months, Sang Jun finally shuts it down. A year later, he’s working as a logger, Eun Gyeong is waiting tables, and their son, Gi Ho, is getting bullied at school. Things are bleak for everyone involved.
Back in the present again (yes, again), Yeong Ha starts noticing more red flags. There’s the overwhelming smell of bleach, missing towels, a replaced toilet brush… and yet he still doesn’t report it. He checks his dashcam footage, which doesn’t show much; just Seong A lugging a suspiciously heavy suitcase to her car. Not exactly damning, but her son isn’t with her…
And what does Yeong Ha do? He buries it. Recleans the entire space. And just… carries on like none of it happened.
Back in the present, a year has passed since the first incident, and Yeong Ha seems to have moved on. He’s prepping the vacation rental for his daughter when surprise! Seong A returns. No sign of her son.
We jump back to the early 2000s, times passed and Sang Jun and Eun Gyeong are trying to sell the motel and start fresh. But when the deal falls through, their fragile optimism quickly unravels. Making things worse, Hyang Cheol, the serial killer, is openly bragging about the murder, continuing to ruin the motel’s reputation. Then things take a devastating turn—Bo Min arrives at the motel to find Eun Gyeong dead in Room 403. Sang Jun is already there, and it becomes clear she died from suicide. Another life ruined by the ripple effect of one event.
Back to the present again, Yeong Ha shares a meal of pasta and tomato sauce with Seong A, which already feels strange given the circumstances. When he wakes up alone on the floor, he realizes something is off. He reaches for help but stops short after finding a note in his pocket: a photo of his daughter with her face circled. A threat loud and clear.
Things spiral. Seong A casually starts moving plants into his house and redecorating like she lives there. She even hires movers to take his furniture out. Yes, seriously. Eventually, Yeong Ha finds her back at the pool where their story began. He grabs her and holds her underwater, but she fakes drowning and stands up the second he lets go. They sit down to dinner, calmly discussing her crimes like it’s a post-murder book club. But there’s a twist: Yeong Ha’s recording the entire conversation. Finally, he decides to take action and drives to the police. A year late, but sure, we’ll take it.
Too bad she crashes her car into his before he can make it inside.
(Note: From this point forward, the 2001 case merges with present-day events. When Gi Ho is mentioned, it refers to his adult self in 2024.)
After the motel incident, Gi Ho grew up consumed by bitterness. With his family broken and his childhood warped by trauma, he became obsessed with Hyang Cheol. He now lives in the abandoned Lake View Motel and spends his days obsessing over the past and practicing with a rifle.
When Yeong Ha learns the full story of what happened at the motel, he becomes paranoid that he’s heading toward the same fate. Torn between staying or selling, he visits the motel himself to investigate and meets Gi Ho. It doesn’t go well. Gi Ho is angry, volatile, and far from welcoming.
In the aftermath, Yeong Ha eventually tracks down Sang Jun, now in a retirement home. Unfortunately, the man is a shell of his former self, mentally stuck in a time when his motel was thriving, as if none of the horror ever happened.
We circle back to Gi Ho and the rifle. Hyang Cheol, the serial killer from 2001, is granted temporary leave from prison to visit his dying mother in the hospital. Gi Ho, fueled by two decades of pain and obsession, sets up in a nearby building to assassinate him. The plan is simple, it’s methodical, he’s practiced it over and over… and he misses.
Not one to give up, Gi Ho races to the hospital to finish the job in person. Meanwhile, Hyang Cheol uses the chaos to assault a few officers, because of course he does. Gi Ho arrives moments later, gets the shot off, and jumps out a window before anyone can stop him.
Meanwhile, Seong A is ambushed by Jae Sik, her (ex?) partner, who demands to know what happened to his son. They fight, and from his side of the story, it’s clear he believes she hurt his child instead of taking her anger out on him. Also, plot twist: she’s not the boy’s mother, but his stepmother. And she tauntingly admits to killing him.
After that lovely encounter, Seong A barrels a van through an art exhibition—because subtlety is dead—and heads straight for Yeong Ha’s rental home. His friend Yong Chae happens to be there and starts arguing with her, unaware of just how dangerous she is. One fight later, he’s been beaten and stabbed within an inch of his life.
Unbothered, Sang A ties him up and casually heads to the store to grab bleach and other red-flag items. When Yeong Ha doesn’t answer her calls (he’s busy cleaning up after Gi Ho’s chaos), she decides to lure his daughter, Ui Seon, instead. Because clearly, this woman is on a mission to destroy everyone involved.
Ui Seon shows up and instantly senses that something is off. They fight, because why not, and Ui Seon ends up unconscious. Cut to Seong A dragging a red suitcase that looks heavy enough to confirm everyone’s worst fears. Finally, she contacts Yeong Ha and baits him into returning. He doesn’t hesitate. He grabs a rifle and goes.
When he arrives, they talk. He manages to rescue Yong Chae and get him to the hospital. Then, because apparently this man has reached peak tolerance for chaos, he goes right back to confront Seong A. She agrees to disappear forever if he keeps his mouth shut. He agrees, but only if he can see his daughter again.
She takes him to the lake with the infamous suitcase. But plot twist: it’s empty. Because she just got played.
Turns out, Bo Min confronted Yeong Ha at the motel before he left. After hearing everything, they devised a plan to stall Seong A while the police searched for Ui Seon. It worked. Once she was safe, Yeong Ha lured Seong A to the lake for her final act of delusion and got her caught in the trap.
Honestly? Not bad for someone who ignored red flags for a year.
Just when it seems like everything’s over… it isn’t. Seong A is released due to “false arrest,” keeping the nightmare alive. Bo Min suspects there’s more to her than the Ui Seon incident and rightfully so.
Meanwhile, Yeong Ha is officially over it. No more waiting. No more hesitating. He decides to take matters into his own hands.
Sung A heads to a laundromat and sets it on fire, because of course she does, while police discover yet another body. Then she returns to the rental home and finds Jae Sik waiting for her, rifle in hand, ready to end everything. Just as he’s about to pull the trigger, Yeong Ha arrives and confesses to covering up the murder.
What follows is a full-on shootout. Jae Sik shoots Sung A in the leg. Sung A shoots Bo Min in the shoulder. Yeong Ha gets shot. Jae Sik chases Sung A down and finally puts an end to it; one bullet to the back, and one to the head. It’s over. But so is the hope of ever finding his son’s body.
What follows is a strange sense of calm. Yeong Ha and Yong Chae return to the rental home from the hospital. Bo Min lets the case go. Jae Sik ends up behind bars again but he’ll be out soon.
The drama closes with Yeong Ha and his family back at the vacation home. He decides to sell it and move closer to his daughter— finally choosing peace over silence. The final shot is Yeong Ha at his desk, staring at a small toy that once belonged to Jae Sik’s son, quietly reflecting on the fact that he let Sung A get away with murder for an entire year— and probably for the rest of her life, had she not come back.
The End.

The Review
The Good
A Mystery Wrapped in a Postcard
I was about to say there was nothing good about this show until I remembered how visually stunning it was. Yeong Ha’s rental home was tucked away in one of the most breathtaking locations I’ve seen in a drama. Even the scenes set in Seoul had a quiet beauty to them. The small town had this eerie, peaceful beauty that weirdly made the whole mess more bearable. If vibes could carry a plot, this show would’ve been a masterpiece.
The Bad
When the Comment Section Becomes a Study Guide
I originally gave this show a 1.5/10 until I dove into the comments and realised other viewers had become full-time detectives trying to make sense of it all. And while I appreciate the effort, that’s exactly the problem. If random internet strangers can explain the story better than the show itself can, something’s off. The first two episodes genuinely pulled me in. But after that? I was lost. Completely. Reading what others pieced together made the plot somewhat make sense in hindsight, but that shouldn’t be the viewer’s job.
Two Timelines, Zero Connection
My biggest issue? The two stories had no meaningful correlation. Aside from the shared presence of the police officer, they may as well have been happening in alternate universes. I spent half the show assuming Sang Jun was Yeong Ha’s younger self but no. Then I thought maybe Yeong Ha had known about the motel incident and his silence tied into that history but also no. Okay, maybe Sang Jun would later advise Yeong Ha or stop him from repeating the same mistakes? triple no. When they finally meet, Sang Jun is already too far gone mentally for any of that to happen.
At the end of the day these weren’t parallel stories, they were just two separate cases loosely glued together by theme. Yeong Ha could’ve sold his property at any time (which he eventually did), had a wealthy daughter, and wasn’t exactly struggling. Sang Jun, on the other hand, poured everything into his motel and lost it all. The serial killer in his timeline left the crime scene covered in evidence, which drew the media and destroyed their lives. Meanwhile, Seong A cleaned up, vanished for a year, and left behind almost nothing for the media to pick apart.
And may I remind you, Yeong Ha got his happy ending. Everyone lived, he became a grandfather, and got to sell his home for (most-likely) a lot of money. Sang Jun lost everything. His wife killed herself, his son became a killer and almost killed himself too, and for a cherry on top, Sang Jun lost his mind and is now trapped in a time that no longer exists. The contrast is so big, it’s almost laughable.
The Proverb Stretch
And that brings us to the frog proverb, “A frog dies from a stone thrown inadvertently.” Which is a poetic way of saying: careless actions can cause unexpected harm. Except in The Frog, no one’s careless. Hyang Cheol knew exactly what he was doing. He was malicious, intentional, and had no regrets. And Seong A? Her actions weren’t accidental, they were extremely personal. If anyone caused damage by accident, it was Yeong Ha, and even then, he was more passive than careless. His suffering came from deliberate inaction, not from being blindsided.
And I won’t lie, I do see how Seong A’s actions got the cop killed, and of course the serial killer wrecked Sang Jun’s life. But let’s be clear: none of it stemmed from ignorance or unintended consequences. They knew exactly what they were doing. The serial killer practically gift-wrapped the evidence, and Seong A didn’t just botch the cleanup, she came back and kept killing. So no, “a frog dies from a stone thrown inadvertently” doesn’t fit here.
This wasn’t carelessness. It was cruelty with intent. A better fit would be “The frog pays for the hand that chooses to strike.” or something because the harm suffered wasn’t accidental—it was the direct consequence of their deliberate, selfish, and malicious actions.
*Edit: thinking back, I realise that the proverb does kind of work with Sang Jun. He innocently gave the killer a room and then the whole thing played out. I assumed the proverb was only towards the perpetrator throwing the stone, not the frog that dies. But I guess it works both ways.*
So yes, thanks to the comments, I kind of get what they were aiming for. But even with the deepest, most forgiving interpretation, it still doesn’t land. Not thematically. Not narratively. Not emotionally.
Plot Convenience Was Doing Overtime
Apparently, the police in this drama were just there for decoration until the final act. Seong A literally rammed Yeong Ha’s car in the middle of the day, in front of a police station and somehow, she’s back home in the next scene like nothing happened. No questions, no charges, not even a mildly curious officer.
And Bo Min? Queen of being suspicious at all the wrong times. She’s always circling the cabin when nothing’s happening, yet nowhere to be found when a cop is killed, a man is beaten nearly to death, and a girl gets choked out. How are you suspicious about the cabin for five episodes straight but miss all the actual crimes?
Then there’s Gi Ho and his magical rifle. In case it needs saying: owning a gun, especially a rifle, in South Korea, is just about impossible— let alone sneaking one around with it, practicing with it, and staging a public hospital assassination without being caught on camera. But somehow, Gi Ho pulls it off. He misses his shot (sigh), dashes through the hospital like he’s in an action movie, shoots the killer point-blank, and escapes through a window. Completely unseen. No security footage. No witnesses. Not even a blurry hospital hallway clip. Apparently, the only CCTV system working in this show is the one in Yeong Ha’s dashcam.
The Man Who Dug His Own Grave (Then Complained About It)
Yeong Ha was his own worst enemy— and mine too, to be honest. Let’s be real, Seong A murdered a child and he just… cleaned it up? Found blood, towels missing, his record player soaked, and thought, “You know what, let’s just bleach it down and pretend none of this happened.” Then he’s surprised when she returns a year later, killing people like it’s a hobby? What did he think would happen?
It’s insane to me that he would’ve let Sung A get away with murder for an entire year, and most likely the rest of her life, had she not come back. He stayed quiet, endangered everyone around him and treated her like a minor inconvenience instead of what she actually was—a literal murderer. He didn’t act scared of her or the police. He just.. wanted the whole thing to go away. And even when he finally did something, it was way too late. Maybe it would’ve made sense if he had some kind of shared trauma with Sang Jun or had witnessed what happened at Lake View Motel, but no. He doesn’t even know until way later. Fear clearly wasn’t driving him because he barely showed any.
And the worst part? He gets a happy ending. After actively endangering everyone around him, wiping away evidence of a brutal child murder, and indirectly getting a cop killed, he ends the show laughing over dinner like he didn’t throw gasoline on the entire plot. Incredible.
The Investigator Who… Mostly Stood There
Can we talk about how Bo Min was supposedly this elite detective with a reputation for solving major cases, but didn’t actually do much? In 2001, she “solved” the motel case by answering a phone call. That’s it. She didn’t catch the serial killer. She didn’t investigate. The other cops found the guy and she mostly just comforted Sang Jun’s wife.
Fast forward to 2024, and it’s the same story. She’s around, sure, but not doing anything. I don’t even remember her having more than two lines until the final act. She was suspicious, sure—but she mostly just stood outside places squinting at things. The one clever move she made was figuring out that Sung A was hiding something in the cornfield. Other than that, she was more of a silent observer than the crime-solving queen the show claimed she was.

What I Would Do
It’s going to be tricky not to completely rewrite the story, but here’s how I’d fix the biggest issues without losing what The Frog was aiming for.
Make the Timelines Actually Matter
This one feels obvious, but the past and present timelines should actually connect. Give them emotional, thematic, and narrative weight, not just surface parallels. Here’s how:
Option One: It’s the Same Guy.
Instead of separating Yeong Ha and Sang Jun into two disconnected stories, make them one person. After barely surviving the Lake View Motel tragedy, Sang Jun reinvents himself as Yeong Ha, swearing he’ll never let history repeat itself. When Seong A enters his life, dropping red flags and bleach everywhere, he hides it— not out of apathy or confusion, but out of fear. He knows exactly what could happen because he’s lived through it. His silence stems from trauma, not carelessness. Suddenly, his behaviour makes a whole lot more sense.
Option Two: The Mentor Arc.
If they must remain separate people, at least make their paths cross in a meaningful way. Sang Jun could become a mentor figure for Yeong Ha—someone who’s already lost everything and warns him not to repeat the same mistakes. Maybe he’s the voice warning Yeong Ha against calling the police, showing him the cost of exposure. That mentorship gives context to Yeong Ha’s choices and makes the callback to Lake View Motel actually matter.
In either version, you get a cleaner link between the two timelines and a stronger emotional through line. What we got instead felt like two separate stories crashing into each other with nothing to bind them but a metaphor.
Make the Proverb Work
The proverb itself isn’t the problem—it’s the execution in the show. Here’s how I’d adjust each story so that the proverb actually fits:
Seong A and Yeong Ha:
For the proverb to hold, the boy’s death should be a direct result of someone’s careless words. For example, maybe Seong A says she’s his stepmother, and, jokingly, his friend comments on how step-parents can never be trusted or how fathers always prioritise their children. While said lightly and without malice, to Seong A, that comment changes everything. A single careless remark would then be the “stone” that sets the tragic chain of events into motion, giving the proverb real weight.
Sang Jun and the Killer:
From Sang Jun’s perspective, the proverb could work, but it needs to reflect the “stone” being thrown by someone else. For instance, instead of the killer acting randomly in the hotel, perhaps a small-time writer covers a haunted hotel story about Lake View Motel to make a few bucks, casually exaggerating a past murder (One that either happened long before Sang Jun opened Lake View Motel or it’s just a lie). The article goes viral, and everyone assumes it’s real. That “stone”—the seemingly harmless story—then sparks a series of events that leads to chaos and harm, giving the proverb a more direct and fitting application.
Let the Cop Actually Be Good at Her Job
Bo Min was allegedly a brilliant detective but the evidence said otherwise. She didn’t solve the 2001 case as the killer basically turned himself in. And in 2024, she mostly lurked ominously without doing much. If she’s supposed to be this infamous case-solver, then show us how.
Instead of the serial killer being caught right away in 2001, maybe someone innocent gets framed. Bo Min steps in, starts pulling threads, and pieces it together using actual detective skills. Then, decades later, she returns as a proactive, obsessive detective. She wouldn’t just lurk with suspicions, she’d find the missing evidence, discover the boy’s body, and bring justice to light. This would give her the reputation and nickname the show tried to give her.
Give her a real presence. Let her do things. And if you’re going to give her a creepy obsession with death, go all in. Maybe she grew up as the daughter of a murderer. Maybe she’s weirdly calm around corpses, touches blood like it’s normal, smiles in morgues. That would actually explain her odd energy and give it weight. Don’t just drop a spooky detail and let it go nowhere. Develop it.

Final Thoughts
This entire drama tried to sell me a frog proverb and yet fed me plot holes, weak connections, and a cast of characters who either did too much or nothing at all. At some point, it stopped being a thriller and started feeling like a cautionary tale about what happens when your protagonist does literally nothing for a year straight.
To be completely honest, The Frog could’ve been a standout drama, if only the writers had committed to weaving the timelines into a single, cohesive story. The biggest issue? There was no meaningful connection between the two plotlines. When Yeong Ha finally met Gi Ho, it should’ve been the moment everything clicked, but instead it barely registered as significant. If they had made them the same person or given Sang Jun a real reason to intervene, some kind of déjà vu storyline, it would’ve elevated the entire show.
But because that never happened, everything else unraveled. Yes, the visuals were beautiful and the acting was solid. But that’s where the praise ends. It felt like the writers trusted us to just “get it” without doing the work to guide us there. And if the only way I can understand your story is by scrolling through comment sections like I’m piecing together a Reddit conspiracy theory? That’s a sign something went very wrong.
I kept waiting. For something to click. For it all to tie together. For the cop to justify her reputation. For the chaos to converge into clarity. Instead, I got beautifully shot confusion and a finale that said, “We good?” when all I had was more questions.
So yes, it looked great. But no amount of cinematic sunsets can hide a plot that forgot to finish the puzzle. Sometimes a story needs to show you the frog instead of just telling you that it jumped.
This review is a bit shorter than usual (can you tell haha) but I hope you still enjoyed it. I recently watched a Chinese drama and had A LOT to say about it, would it weird to review it on a Korean drama/movie review blog?? I won’t be able to do a description for it but I think it could still be fun.
