Welcome to Insung, Where Dreams and Jaws Get Broken
Insung city isn’t your run-of-the-mill metropolis. It’s the place where dreams get crushed harder than your morning coffee beans and fists fly faster than rush hour. Into this crime-ridden chaos comes a new breed of justice warriors: ex-athletes turned police officers. No, they’re not here to win medals anymore. They’re here to clean up the streets — preferably with a punch, a discus, or a broomstick.

TL;DR:
- Ex-athletes form a new police unit in a chaotic city.
- They battle corruption, crime, and past scandals.
- Features a hot-headed boxer, sharp shooter, and strategic fencer.
- Their unconventional methods lead to viral heroics.
- Uncovers a mole within the police force and a sinister coaching plot.
- A blend of action, humor, and emotional depth.
Meet the Medalists with a Badge

Leading this ragtag group of righteous bruisers is YOON DONG-JOO, played with peak charisma by Park Bo-gum. Dong-joo is your classic hot-headed ex-boxer with a heart the size of his biceps. After landing himself in hot water (read: demoted) for smashing corrupt colleagues, he’s back in Insung. Oh, and did we mention the doping scandal that tainted his gold medal? He was cleared, sure. But the court of public opinion isn’t exactly handing out apologies.

Then there’s JI HANNA (Kim So-hyun), a.k.a. the “Shooting Fairy.” She could probably take out a pigeon mid-flight with her air rifle, but instead, she’s stuck pushing paperwork and being the agency’s walking PR campaign. Hanna wants field action, not fans.
Also entering stage left is KIM JONG-HYEON (Lee Sang-yi), an ex-fencer and current clean-up guy for corruption. He got a special promotion after exposing dirty cops, but unsurprisingly, he’s not on anyone’s Christmas card list at the precinct. Oh, and he used to date Hanna, which totally rubs Dong-joo the wrong way. You can feel the bromantic tension boiling over.
Let’s not forget SHIN JAE-HONG (Tae Won-seok), the human discus cannon. His promotion was sabotaged, possibly by the very crusade Jong-hyeon launched. Now he’s stuck managing traffic, but don’t be fooled — this man’s got the strength of ten office chairs.
Finally, we have GO MAN-SHIK (Heo Sung-tae), the Greco-Roman gentle giant. With 14 years in the force and nothing to show for it, he’s the butt of every joke in the office. But he’s about to change that. Maybe. Hopefully.
Case One: Gold Bunny and the Boom Boom Betrayal

Things start off with a literal bang when Dong-joo and Man-shik botch the arrest of a smuggling gang leader known as Golden Bunny. It wasn’t exactly their fault — someone set off an explosion mid-operation. Bunny hops away, and guess who gets the blame? Yup.
But wait, there’s more! A hit-and-run happens under Dong-joo’s watch, and the getaway vehicle looks suspiciously familiar. He suspects it’s tied to Bunny, but nobody listens. Classic rookie move: having common sense.
Jong-hyeon, being Mr. Analytical, digs through footage and discovers that the explosion was orchestrated, reported early, and — plot twist — there’s a mole in the force. It’s giving Mission: Improbable. The dead hit-and-run victim? A customs agent who tipped off Man-shik. Oh snap.
And if things weren’t messy enough, Dong-joo gets lured into a trap by a fake tip. Bunny gang, one. Dong-joo, zip.
Break-Ins, Snake Gangs, and Seriously Bad Timing
Hanna’s subplot gets darker. She delivers the agent’s belongings to the grieving family, only to keep them when she suspects something’s off. That night, goons break into her place hunting for a document. Jong-hyeon hears the struggle over the phone but gets ambushed by a snake gang on his way over. Timing, people. Ever heard of a calendar?
It all erupts into synchronized chaos. Hanna shoots her way out. Dong-joo lands punches like it’s a championship match. Jong-hyeon fights with a broom. Jae-hong? Oh, he hurls a manhole cover like it’s a frisbee. Even Man-shik gets his moment, wrestling another officer just to secure backup. Because apparently, bureaucracy is solved with suplexes now.
Birth of the Misfit Avengers
Their heroics go viral. Suddenly, they’re media darlings. Man-shik seizes the opportunity to pitch a new Special Criminal Investigation Team. Surprisingly, it gets approved — though only for PR stunts.
Everyone joins: Hanna for field work, Dong-joo to tail Hanna like a lovesick Labrador, Jae-hong for that long-overdue promotion. Jong-hyeon? He stays officially solo but remains the secret sauce of competence.
Hanna’s PR rage reaches a boiling point when she “accidentally” shoots the commissioner to demonstrate a faulty vest. What was he expecting, flowers? She resigns. Dong-joo confesses. She shuts him down. All in a day’s heartbreak.
Mole-Hunting With a Side of Hallucinations
The team receives a tip that two of the home invaders are hiding out. En route, Man-shik eats candy laced with hallucinogens — from an evidence box, no less. This results in a safe house bust that looks like an improv sketch gone wrong.
During the chaos, Jong-hyeon freezes from trauma. He nearly gets stabbed but Man-shik takes the blow (with flair). Dong-joo rushes him to the hospital in a shopping cart. That’s right. They carted a bleeding man through city traffic like it was a grocery run.
Truth Comes Crawling Out
Just when things seem hopeless, the hit-and-run culprit turns himself in. Surprise: it’s Dong-joo’s old boxing buddy, LEE GYEONG-IL. He’s clearly being manipulated. Guess who’s pulling the strings? Coach OH JONG-GU, Dong-joo’s shady ex-mentor.
This guy has dirt under every fingernail. He doped Dong-joo, ruined Gyeong-il with painkillers, and runs a shady security firm. Dong-joo puts the puzzle together: Gyeong-il is covering for someone. Likely under duress.
Personal Opinions: Let’s Talk About the Grit, Guts, and Glorious Chaos

There’s a lot going on in these first two episodes. On the surface, it’s a buddy cop drama with a side of sports nostalgia. But underneath? It’s a biting critique of institutional rot, PR over substance, and how society handles fall-from-grace athletes.
Park Bo-gum brings Dong-joo’s rage and vulnerability to life with surprising nuance. Kim So-hyun is equally compelling, flipping between frustration and resolve. The supporting cast? Unmatched in comedic timing and raw emotion.
The pacing is relentless, yet the storytelling doesn’t trip over itself. Each character gets a piece of the spotlight without cluttering the narrative. And the action scenes? Absolutely bonkers in the best way. You haven’t lived until you’ve seen a manhole cover stop a car.
What works best is the emotional backbone. These aren’t just ex-athletes; they’re discarded heroes trying to matter again. Their pain isn’t just physical; it’s deeply tied to a broken system. You want them to win, not just because they’re charming but because they’ve earned it.
Final Verdict: 4.5/5 Stars ✭✭✭✭✮
Good Boy starts off swinging — literally. It packs charm, chaos, and just enough emotional grit to keep you locked in. If the first two episodes are any indication, we’re in for a wild, heartfelt ride. Let’s just hope the next villain isn’t allergic to manhole covers.
