The Premise Runs Out of Money
Cashero presents itself as a deft combination of superhero spectacle and social commentary, but the series ultimately falters due to its lack of narrative clarity and discipline. What begins as an intriguing and socially attuned premise deteriorates into a confused and unevenly written drama.The story follows Kang Sang-ung, a timid civil servant whose distant and abrasive father leaves him with an unwanted supernatural ability. Sang-ung can access extraordinary physical strength only when carrying physical cash. The greater the amount of money on his person, the stronger he becomes, yet every use of the power directly consumes that cash. Within the South Korean context, where housing insecurity and financial anxiety shape the lives of many young adults, the metaphor is immediately resonant.
Sang-ung has no desire to become a hero. His ambitions are modest and personal, focused solely on saving enough money to buy an apartment with his girlfriend, Kim Min-suk, an accountant. Acts of altruism are something he actively avoids, and only external pressures force him into reluctant intervention.
In its early episodes, Cashero gestures toward a compelling ethical dilemma. The tension between personal survival and social responsibility is briefly explored through the mechanics of Sang-ung’s power. Because his strength depends entirely on liquid cash rather than credit cards, every sudden influx of money becomes a ticking clock. The question of whether he can secure his savings before being compelled into action initially provides narrative urgency.
This tension is squandered almost immediately. A prolonged early arc centered on an unexpected bag of cash exhausts the concept in one stroke, leaving little room for escalation or variation. What should have been an enduring source of suspense instead becomes a prematurely resolved gimmick.
Despite the conceptual richness of its premise, the series rarely examines its implications beyond surface-level humor. Recurrent jokes about masculinity and financial worth, such as Min-suk secretly adding bills to Sang-ung’s wallet to test his strength, substitute for meaningful character development. Kim Hye-jun, frequently cast in assertive and complex roles, is confined to a reductive portrayal of a nagging, money-obsessed partner. Sang-ung, meanwhile, drifts through the narrative with minimal growth, protected from accountability by the show’s indulgent framing of his reluctance.
The series briefly improves when it introduces a wider ensemble of misfit heroes. Byeon Ho-in can phase through walls only when intoxicated, while Bang Eun-mi’s telekinesis is activated through binge eating. These characters provide moments of tonal relief and comic potential, yet they remain largely underused, functioning as background figures rather than narrative drivers.
As an action drama, Cashero feels generic and underpowered. Its visual effects and fight choreography lack distinction, particularly when compared with more accomplished Korean superhero series that have demonstrated greater ambition and coherence.
The most damaging flaw, however, lies in the writing itself. The series repeatedly undermines its emotional stakes through abrupt tonal shifts and a failure to maintain narrative continuity. In one especially jarring moment, Sang-ung witnesses people die violently at the hands of the villain Jonathan, only for the story to immediately pivot to a warm domestic scene in which his trauma appears to have vanished entirely.
From scene to scene, Cashero struggles to define its identity. It piles up effects-driven set pieces and incompatible emotional beats, then leaves us to reconcile the contradictions on our own.
The opening episode hints at a sharper and more disciplined series. What follows is a steady and disappointing unraveling.

zero cash
I don't the the premise is bad... Sang-ung inherits superhuman strength that only activates when he is holding cold hard cash, and using it literally drains his life savings. For a young guy... under the weight of the Korean property ladder, trying to save every won for a apt with his girlfriend, that should be a relatable experience. It is the perfect setup for a look at the trade off between having a soul and having a future. Instead, it is bascially treated ow level panic like a boring chore.The script is in such a frantic hurry to become a generic thriller that it burns through its narrative capital before the the midway point of the 2nd episode. Sang-ung gets a surprise bag of cash and suddenly the stakes just evaporate. The novelty is spent before it even has a chance to breathe. It is lazy writing. Instead of exploring the actual, grinding realitya of the cash hero life, we get these occasional low hanging jokes where Min-suk slips him a 50k to test his whatever in the bedroom. It is disappointing and just insulting. I sat there waiting for a precise exploration of financial sacrifice, but I just got cheap gags and a narrative that lacks any real spine.
The chemistry between the leads is a total desert. I am told they have been together for nine years, but I see zero evidence of a shared history or a single spark of heat. I just don't feel any emotions sometimes. I actually find Min-suk to be the only rational person in this disaster. Her constant anger is the only thing that feels human.
After nine years of stagnation, of course she wants a good life and a nice place to live. That money conflict is a grounded, relatable tragedy, but because the actors have the collective energy of a cold rehearsal, her valid frustrations are just dismissed as nagging. It is a waste of a relationship that should have been the heart of the show.
The writing is just emotionally incoherent. In one scene, Sang-ung is horrified to watch civilians falling to their deaths, looking like his entire world has collapsed. Then, a single jump cut later, he is at home smiling at his sleeping girlfriend like he just had a nice day at the office. It is insulting to the audience. Even the sidekicks are wasted potential. Byeon Ho-in, who moves through walls when he is drunk, or Bang Eun-mi, who uses telekinesis via snacks, are fun touches, but the show just leaves them on standby. they are tools for a lead who is essentially a cardboard cutout.
This is a konglish mess that mashes up social themes and superhero thrills without a single ounce of finesse. It refuses to build a world where money actually matters or feels like a real burden. It left me with nothing. IIt offers zero interest on the time you invest. It traded a clever look at the suckiness of financial stress for a pile of clichés and hoped the gimmicks would hide the rot.

One of the worst k-dramas released in 2025
Honestly, I can't point out one thing that I enjoyed about this drama. Sure, it had an unique premise, superhero who needs money to have powers, but writing went downhill pretty quickly. The pacing was horrendous. There were long scenes featuring antagonists doing their "evil stuff". This drama is something I literally finished only because I wanted to see how bad it could get. Spoiler alert: it got pretty bad. The biggest issue was the directing. Why do we need to see character in every angle before he/she moves? There was also a weird camera sequence in last episode with the apartment building. The editing didn’t help either, nor did the soundtrack choices. Why play intense instrumental track after someone at the gunpoint doesn't get his brains blown out?It might sound harsh, but I couldn't tell whether the acting was bad because of the editing or it was just generally bad. After Typhoon Family, what a downgrade this drama is for Lee Junho. It's not even worse recent performance by him but for most of the cast. I'm only pointing him out because he was the one who made me tune in for this drama. The rest of the cast doesn't have that star power.
This drama feels like something only a five-year-old could enjoy.

Not All Heroes Wear Red Undies (Some Wear White)
This drama is the perfect popcorn flick—lightweight, fast-paced, action-packed, and highly entertaining, with a quirky Western-style format infused with a distinctly Korean flair. Across its eight episodes (each just under an hour), it stays consistent in tone, delivering humor, heart, and a dash of chaos.LOVE, MONEY, AND A PUSHY GIRLFRIEND
At first glance, it’s your classic “everyday Joe turns superhero” story—but with a twist. Instead of a bullied loser, we have Kang Sang Woong, an ordinary civil servant who’s often a pushover in his nine-year relationship with Kim Min-sook. She’s bossy, pragmatic, and entirely goal-oriented (save money, buy a house, get married), which sometimes makes her seem selfish. But beneath her no-nonsense exterior, Min-sook genuinely cares for Sang Woong, supporting him in her own practical way and fiercely defending him when it counts. Their relationship is a realistic yin-and-yang dynamic—he’s the willing loser, and she’s the determined planner. It’s not the most romantic setup, but it’s grounded, relatable, and built on a foundation of love.
SUPERPOWERS ON A BUDGET
The real kicker? Sang Woong’s superhuman strength only works when he’s flush with cash—and every time he uses his powers, his money pulls a disappearing act. This clever twist sets up a journey of self-discovery, exploring themes of money, power, and what it truly means to be a hero. Through his internal monologues, we see him grow—rebuilding his bond with his dad, gaining confidence at work, and finding his footing in life. It’s a fresh take on the superhero genre, blending humor with heartfelt moments.
HIGH-WAISTED HEROICS
Lee Junho absolutely nails the role of Sang Woong, bringing to life an awkward, reluctant superhero. He’s selfish, clueless, kind, greedy, weak, and strong—sometimes all at once. His comedic timing is gold, especially in the early scenes where he’s hilariously told to conserve energy and avoid helping others. And let’s not forget the unforgettable moment when Bang Eun-Mi gifts him those special high-waisted white undies to stop coins from falling everywhere—a practical yet deeply awkward solution that perfectly captures the show’s quirky charm. Sang Woong’s internal monologue about how even his girlfriend hasn’t gotten him underwear adds a layer of humor and self-deprecating charm. His sibling-like dynamic with Eun-Mi is a standout, and the moment she pins his ruined suit is unexpectedly heartwarming.
VILLAINS STRAIGHT OUT OF A COMIC BOOK
The rest of the cast is equally stellar. Kang Han-na lights up every scene she’s in, and the ensemble cast turns this action-packed drama into an acting showcase. However, the fast-paced nature of the show leaves little room for deeper character developments or backstories. The villains, while entertaining, feel cartoonish at times. We never really learn the origins of the "Criminals’ Association," the sibling rivalry between Jo An-na and Jo Na-than, or the relationships involving Park Jeong Ja and Jo Won-do. Even Sang Woong’s dad’s story feels a bit underexplored. But in a show that’s more about heart and humor than complexity, they serve their purpose as chaotic forces that keep the action moving.
A HERO’S TRUE POWER
That said, this drama isn’t trying to be deep. It’s a fun, action-filled ride with a solid message—not just about power and money, but also about responsibility, self-discovery, and what it truly means to rise to the occasion. It’s a powerful reminder that being a hero isn’t about perfection or superhuman abilities—it’s about courage, community, and the strength to overcome challenges when it matters most. (Though, let’s be honest, Junho’s shirtless bathroom scene deserves its own standing ovation for heroism of a different kind.)

The most boring action-drama I have ever watched!!!
I had really high expectations for this drama but it was a HUGE disappointment… The trailer was promising and the cast looked phenomenal! Lacked in story-writing and character development especially, but there were more flaws as well.Reasons why I didn’t like it:
1. A lot of things didn’t make sense or were hard to follow. For example, why did his father have to give him the superpower??? Like what would happen if he died without giving it to his son??? It was so unclear! The explanations in general were so sloppy and the motives behind the characters were not properlt explained. Also, what’s the deal with Jo Anna and Nathan? Why do they want these superpowers??? Whats their reason or motive to be so strong??? Did sth happen to them in their childhood??? Like for example Strong Girl Namsoon had an amazing villain (played by Byeon Woo Seok) who had a crazy, traumatic childhood. So the motive of his actions of trying to get that superpower is clear. But WHATTTT is the reason for the villains of this drama???? Why do they want that superpower so badly???? I just couldn’t understand and was sooo annoyed!!!!
2. Explosions, explosions, explosions! This drama thought it could be make up for the lacking storytelling by blowing up stuff constantly. It was literally trying to be like one of those American superhero movies. It definitely felt like one! We need Netflix to stop ruining K-Drama by trying to Americanize them…
3. Flat characters! Although I liked Sung-Un and Bun-mi (and the fire girl too), I just couldn’t properly connect to any of the characters. We barely got to know them on a deeper level and there was basically no character development either. Everything just stayed the same with the exceptions of a few explosions here and there…
Other things that didn’t make sense or bothered me:
- Episode 2 when there are the explosions inside the wedding hall and ML saves his girlfriend and then they just stand there and talk and he gets scolded by her for wasting money again 🙄🙄🙄 LIKE WTF ARE YOU DOING???? Get out there! All I could do is roll my eyes!!! I was SOOO ANNOYED!!!!
- In episode 4 or 5 when Sang-un is trying to get into Beomha ranch and then the two othet friends, Bun-mi and the attorney are trying to stop him… I just didnt understand the whole sideplot thing with the selling your superpowers. Did the alcoholic attorney try to deceive them??? Was it on purpose the note he wrote on the documents? What exactly happened? Why were Bun-mi and Sang-un mad at him and What made them forgive him???? I did not understand anything at all! Not understanding these made me feel so frustrated!!!!
- When Sang-un and Attorney are running away from the lab and ML drops the bag and it get stuck under the sliding wall and instead of focusing on the bag he ANSWERS HIS FCKING PHONEEEE!!!!! 😩😩😩😩 Uggghhhh!!!! I was sooo annoyeddddd at him and Min-Suk!!!! I also didn’t like her at all!!!! She was SO ANNOYING!!!!! 😫😫😫
- When they find out the police officer’s superpower is timetravel and when Min-Suk goes to the police station to ask him to turn back time and save ML, and the police officer just HANDS HER his watch???!?!??!!! IS THAT EVEN A SUPERPOWER????? It’s literally Hermione’s Timeturner!!! And it’s not HIM who has the superpowet but HIS WATCH which in that case it is a magical object that ANYONE can use???? Omg I was faceslapping myself!!! This was so bad!!!! Who tf wrote this???? I swear I could have done a better job!!!
-And then the last scene! Nathan turned into a supervillain and killed the labgirl and all the lab workers. Hmmm? I wonder who is gonna insert Sang-un’s superpowers into him??? 🤔🤔🤔 Again a very nonsensical, annoying scene with actions that made absolutely no sense to the plot moving on.
-The last fighting scene was so cliche too!!! Everyone throwing theit money for him… Awww! I am sooo touched!!!! Omg seriously! I neithet laughed nor cried while watching this drama! I was also not on the edge of my seat… it was just annoying and ridiculous!!!
Other than the amazing cast of actors there was nothing positive to say about this drama… Just don’t watch it!!!

BRO, THIS SHOW... I CAN'T.
The concept is FIRE. Hero powers tied to money and losing cash whenever he uses them.. could’ve been HILARIOUS, absurd, and clever. But instead its grim, serious, NO LOGIC.They literally erase their own rules whenever it’s convenient. Episode 3 could say one thing, episode 6 would say “nah forget that,” then episode 8 revives ep 3's logic?!
Episode 8 ends with the heroes “winning,” sang-ung and his wife get the apartment they wanted, happy music plays… and I can’t even enjoy it because everything leading there was straight bullshit!!
The detective is dumb, the wife is a liability, the "villains" keeps winning, and the pacing is all over the place. Scenes that should’ve been in the finale were smushed across episodes, NOTHING makes sense. Everything feels compacted and stretched at the same time, I feel like the show just threw spaghetti at the wall every episode and hoped we’d eat it.
Honestly, this could’ve been so much fun. Make it playful, and lean into the absurdity of cash-powered heroics. Make the protagonist a high schooler struggling to pay for his powers or face itchy red bumps. Could've Kept the wife out of the loop so we can enjoy the sneaky tension. Commit to rules! Just don’t erase your own universe? Boom! instant better show!!
Instead, we got this nonsense. I hate it... I feel like a loser for watching it, but also like… I needed to finish it to fully understand the madness. If anyone asks me, it’s a hot mess. BUT, I swear this is the kind of chaos that makes you feel alive, even if it’s infuriating.

muy completa a pesar de ser solo 8 caps
quede wow, super completo todo, la ame.Llore, rei y me asuste, pero fue un final lindo, pudo ser un poco más sobre la chica del fuego, pero bueno. La recomiendo mucho.
Al principio me estresaba mucho lo del dinero y hasta a mi me dolieron esos 30 millones jajaj, fue muy refrescante ver como todos los malos fueron castigados y me dio pesar que Jonathan matará a la chica velocista, pensé que estaban enamorados o algo por el estilo, pero la mato de forma super cruel cuando ella siempre estuvo para él. Debieron dar un pequeño contexto de el porque ella hacia tanto por él, cómo que la ayudó en algún momento o algo. Hasta pensé que el man era bueno y queria ayudarlos, luego resultó ser peor 😣

Fell for a tiktok edit and loved this more than I thought
Love Kim Hyanggi and when I saw a tiktok edit of her in this show I knew I had to watch. I also love Junho since Rain or Shine. While I wish Hyanggi was in the show a little more I loved everything else, except Minsuk. I don't know what it was but since the first episode I could not watch any scenes with her in them. I honestly skipped them and it didn't effect watchability or the story in my mind. Chaemin gave a 10/10 performance and it was nice seeing him in more emotional roles even if it is as a psychopath.Was this review helpful to you?
Wacky n Cathartic
One of the wackiest concepts I ever seen in a kdrama lol. I was all for it, but lowkey weary about the approach. Will they take it too seriously? Will they beat you over the head with the on the nose financial crisis messaging?Turns out no, it's self aware from the very get, instantly loveable, and actually peppers in the message in a fun way.
I do think this suffers from the typical *not fully thought out* disease that korean stuff falls into more and more lately, stacking up the plot holes and stretching feasibility in exchange for all momentum, but in this case it kinda plays into the concept. Money itself becomes a character equally defined by its complete power and elusiveness.
From the way it wraps up though, I get the sense they wanna push for a second season here. A bunch of stuff is left open and that message is never taken full circle.
Alas. Binged over the course of a day. It's a good quick fix mood booster.

Had more expectations
Honestly, I started this drama because I really like Junho as an actor and Lee Chaemin is also a very good addition to the cast. The plot originally seemed very interesting, a superhero inheriting his powers and learning that all good comes with a price, that we all have to pay something for doing what's good.What initially irked me was the FL, the way she acted and the way she didn't even seem to be in love with the ML. Honestly, I get she was a struggling woman but most of the times she had me wondering if she really loved him or gave a penny over how he felt and if he was happy. She had really unreasonable thinking and acting many times, making ML feel like a clueless puppy that was mostly scared of her rather than in love with her.
The plot holes were also an issue, as despite the plot being very original and promising, the drama felt a bit rushed and halfway done. The biggest example was the final battle of Junho and Chaemin, when the villain had injected all the powers in him and he was apparently "undefeated". The writers spared no second thought but just making him lose only by being tied by some electricity cables.
Other than that, the cast was really good, but everything went down super fast. Would be way better if they gave this show some more episodes.

A TOTAL SNOOZE FEST
i watched it all in 1 sitting and found the entire drama literally pointless it doesn't give you the feeling of joy when watching but just mindlessly lackluster entertaiment as u try not to sleep through the entire thing. Almost all the characters are one dimensional with no character growth,the fight scenes are crafted as these over the top fight for your life kind of things but lack the substance to do so it was like i was watching 2 people fight each other for no reason there were some fights i didn’t even want the ML to win just to spice things up to shake off the feeling of absolute boredom and this K drama truly has the potential for the worst written Villians because they were so useless and non scary i was so confused the entire time. South Korea wants to write Superhero dramas but forget the reason why we love our superheros they are funny charismatic and engaging,literally every superhero in this show could have died without me caring because i didnt connect to a single charcter. Comparing it to another famous superhero Drama MOVING, i think that drama fully made the audience actually like their superheros we saw them as regular human beings but faced with Great power and became absorbed in their lives this drama however failed to do that woefully.Even the supposed ML and FL were boring as a dimlit candle i found myself wondering why i ever decided to watch this show in the first place?But in the end of the day i can't say it's the worst Korean drama in the world and it definitely serves as a background noise to sleeping at most but what the heck give it a try if u will.

Would you sacrifice 30 million won to save a bus full of people?
Another superhero drama this year; however, compared to ‘Twelve’, it’s way, way better. With only 8 episodes, it’s definitely a binge-watch. As it’s about superheroes, you can’t take it too seriously. Yes, it often doesn’t make sense. And yes, the superpower seems useless since Sang Ung needs money in order to use it. But, superheroes don’t make sense in general. So what? If you don’t expect too much from it, it’s quite fun.What makes Sang Ung’s power dramatic is that it does come with a price (literally and metaphorically) - he has to use his own money. That’s where the calculation comes into play, and Sang Ung faces countless difficult choices. Sacrificing his hard-earned money and so giving up on his dreams partially, just to save innocent people, proves his pure heart, making him a true superhero.
The character that intrigued me the most was the mysterious shark loan lady. Was she really a villain? What was her deal? And who was she really?
The ending with people cheering for Sang Ung, giving him their money (even the police!), so that he can defeat Nathan once and for all. That was actually touching. Also, Sang Ung showing Nathan the middle finger - hilarious.
I also liked the going back in time part - it was a better plot choice than Sang Ung miraculously surviving on his own or something like that.
As for Sang Ung's father - he was just the worst. Didn't explain anything, just let Sang Ung roll with his new circumstances. Also, if he's retired now and actually able to save money then idk maybe pay off your debt instead of having Sang Ung deal with it?? Pissed me off...
Overall, it's a decent drama. Definitely not something special, but it's not as bad as people make it out to be. I've seen far worse this year alone.
