Good Boy (2025): When Sportsmanship Meets Hunger for Justice #425

The Korean drama Good Boy (2025) landed right in the middle of my summer break—a time when I was practically living on a steady diet of K-dramas for breakfast, lunch, and dinner. Honestly, I wasn’t planning to watch it at first. Action-comedy? Meh. I don’t usually enjoy watching violence for entertainment. But then, those hilarious YouTube shorts from the early episodes started popping up on my feed, and slowly… I got hooked.

I had just finished Love in the Moonlight (2016), so I was already deep into my Park Bo-gum obsession. And let’s be honest, I am NOT the kind of person who can patiently wait for two episodes per week like a normal viewer. Nope. I watched other shows and circled back to Good Boy when only two episodes were left, so I could binge it properly.

And let me tell you—what a ride.

Plot of Good Boy (2025)

We meet five former Olympic medalists who, after their athletic glory days, have retired from sports and now serve as police officers in Korea:

1. Yoon Dong-ju – Gold-medal middleweight boxer (Park Bo-gum)
2. Ji Han-na – Gold-medal “shooting fairy” (Kim So-hyun)
3. Kim Jong-hyun – Silver-medal fencing legend (Lee Sang-yi)
4. Ko Man-sik – Bronze-medal wrestling champion (Heo Seong-tae)
5. Shin Jae-hong – Bronze-medal discus thrower (Tae Won-seok)

Once celebrated and adored by the nation, this team of champions now lives far from the glamour, struggling with obscurity and disappointment. Dong-ju, in particular, finds it difficult to compromise his values when he sees corruption spreading within the police force. His inability to look the other way eventually lands the group in trouble, and they’re all reassigned to a seemingly meaningless “special investigation team” under Man-sik. But, of course, that’s just the beginning.

Dong-ju’s Backstory

Dong-ju is basically golden retriever energy in human form—bright smile, kind heart—but behind all that sunshine lies a dark, painful past. He grew up with an abusive, alcoholic father and watched his mother suffer under the same violence until he lost both parents. Bullied as a student, Dong-ju eventually found boxing thanks to Man-sik, who became his mentor and guardian angel.

But his tragedies didn’t stop there. He secretly suffers from punch-drunk syndrome, a neurological disorder caused by repeated head trauma. Despite his deteriorating health, he pushed through the pain to compete in the Olympics—and won gold. Later, when he refused his coach’s proposal to switch to MMA, he was slapped with false doping allegations that destroyed his career.

Adding to his guilt, Dong-ju once injured his opponent during a match, leaving the other boxer unable to fight again. Ever since, Dong-ju has been quietly paying his medical bills and caring for his opponent’s elderly mother as if she were his own.

Man-sik, always his protector, eventually guided him into joining the police, and later, the special investigation team.

Han-na’s Backstory

Ji Han-na, nicknamed the “shooting fairy” for her beauty and skill, was once an Olympic darling and a brand ambassador for countless endorsements. But her glittering public life masked a lonely childhood—her father, a cop, died under mysterious circumstances, while her mother drifted from one partner to another, neglecting her entirely.

At work, Han-na faces discrimination and jealousy from colleagues who see her as nothing more than a pretty face from the sports world. She craves the thrill she once had as an athlete, and joining the special team reignites that fire.

She also hides a medical condition that sometimes causes her to collapse—something known only to her closest friends.

Jong-hyun’s Backstory

Kim Jong-hyun comes from a wealthy, influential family—his father an industrialist, his brother a chief prosecutor. Yet despite his silver medal in fencing, he never once earned his family’s approval.

His final fencing match ended in disaster: an ankle fracture that forced him to retire, paired with the trauma of developing a deep fear of sharp objects. His privilege shields him in some ways, but his emotional wounds run deep.

The Special Investigation Team

Man-sik, the middle-aged wrestler turned cop, brings all five Olympians together under the banner of a new “special crime investigation team.” At first, everyone realizes it’s just a PR stunt—meant for namesake, not actual policing. But the team refuses to sit quietly. Against resistance from peers and higher officials, they begin solving real cases, often at great personal cost.

Their investigations eventually lead them to the true mastermind behind Insung City’s corruption: Min Ju-yeong (Oh Jung-se), a seemingly ordinary customs officer with terrifying influence. His empire stretches into money laundering, smuggling, drug distribution, chemical weapons manufacturing, and even murder. His bloodstained money touches every level of society, making him nearly untouchable.

What makes it worse? Min Ju-yeong takes a special interest in Dong-ju. He plays cat-and-mouse games, taunting him, leading him just far enough without ever being caught. Dong-ju and his team give everything they have to bring him down, even when the system is stacked against them.

And that, in essence, is the heart of Good Boy.

The Romance

Dong-ju, Han-na, and Jong-hyun first met at the training academy. Back then, Dong-ju had an obvious crush on Han-na, and though she liked him back, nothing ever came of it. Their dynamic? Classic golden retriever (Dong-ju) and black cat (Han-na).

Jong-hyun, meanwhile, also loved Han-na and even dated her briefly. Eventually they broke up, though his feelings for her never faded.

When the three reunite in the special team, their emotions resurface. Dong-ju begins pursuing Han-na again, though she resists at first. Han-na gently but firmly rejects Jong-hyun’s hopes of reconciliation. Over time, fighting side by side through danger and loss, Dong-ju and Han-na grow closer, while Jong-hyun steps back gracefully.

The romance isn’t the focus of the drama, but it’s beautifully woven in—no over-the-top slow-motion proposals, just a natural unfolding of two people finding their way to each other.

The Bromance

Now listen, I cannot—cannot—wrap up a review of Good Boy without bowing to the bromance between Dong-ju and Jong-hyun. Lee Sang-yi as the second lead has my heart forever (he already stole it in Hometown Cha-Cha-Cha).

From the start, Jong-hyun envied Dong-ju, mostly because of Han-na. But even with that rivalry, he never once betrayed him. Instead, he became the closest thing Dong-ju has to family.

Dong-ju, who has no home, no family, and a secret illness, is shielded by Jong-hyun’s loyalty. He looks out for him, protects him, and even risks his life for him. And Dong-ju, for all his jealousy, cannot stand anyone hurting Jong-hyun. Their friendship is layered, tender, and easily one of the most touching parts of the show.

The OST

One word: addictive.

The soundtrack is the perfect mix of hype, heartbreak, and healing. Standout tracks include:

• “Time Lapse” (Junny & Katseye) – bittersweet and haunting, the song I keep replaying.
• “Get in the Ring” (MAX) – pure adrenaline, practically Dong-ju’s anthem.
• “Your Name” (Collie) – beautifully tied to Min Ju-yeong’s chilling presence.
• “Waterfall” (Park Bo-gum) – because of course, Bo-gum always blesses us with at least one OST track, and it never disappoints.

The music doesn’t just fill the background—it amplifies every emotion, making punches hit harder and quiet moments linger longer.

Some of My Favorite Scenes from the Show

1. Boxer-Cop Entrance – Early on, Dong-ju dons his jaw protector engraved with “justice,” and the boxer-cop is born. That nose-crunch? If you know, you know.
2. The Car Stunt – Dong-ju literally throws himself onto a moving car to stop Min Ju-yeong from fleeing. He ends up in the hospital, only to watch his enemy walk free. Jae-hong scoops him up like a child to stop him from fighting again—it’s both heartbreaking and endearing.
3. The Eating Scenes – Dong-ju and Min Ju-yeong’s shared lunches, with Dong-ju stuffing his face unapologetically. Finally, a K-drama where the lead actually eats!
4. Min Ju-yeong’s Theme – Every time “Your Name” plays, his chilling aura fills the screen. Oh Jung-se’s acting makes you hate him with your whole being.
5. Han-na’s Lesson – Han-na shoots her police chief in his bulletproof vest to teach him a lesson. Kim So-hyun embodies Han-na’s balance of coolness, competence, and hidden warmth flawlessly.

Final Verdict

Overall rating: 8/10.

This was my very first action-genre drama, so I can’t judge the fight choreography too harshly. But yes, sometimes the violence was a bit much for me—I did skip a few scenes. And let’s be real: how do these characters get beaten to a pulp, vomit liters of blood, and show up fine the next morning with only a scratch or two? K-drama magic, I guess.

I also wish the connection between Dong-ju and Min Ju-yeong had been explored more deeply—it could’ve added another layer of complexity to the story. At times, the comedy felt oddly placed, and the plot could have been tighter.

But what really makes Good Boy shine is its cast. Park Bo-gum shows a whole new side of himself as Yoon Dong-ju, and it feels natural, not forced. Kim So-hyun, Lee Sang-yi, and the rest of the team bring their characters to life beautifully.

And of course, I’m still playing Time Lapse on repeat.

That’s all for today. Thanks for stopping by. Check out another blog-review here:
