Good Boy- Episodes 9-10

Shipyard Showdowns, Stolen Drugs, and a Bullet with a Name on It

Episode 9 of Good Boy opens with a glimpse into the past, Sao Paulo, 2018, where we finally learn the origin of Jong-hyeon’s fencing injury. He twisted his ankle saving Han-na from a speeding car, and that initial strain led to the devastating eye injury that ended his athletic career. Back then, Jong-hyeon pushed through the pain. Today, that same grit keeps him fighting in a far more dangerous arena.

And he needs every ounce of it.

Ju-yeong launches a full-scale ambush with his goons, and the SCIT team is hit hard. Jae-hong is knocked out early, and the rest scramble to survive. Han-na holds the line with a shotgun (and serious badass energy), but the numbers aren’t in their favor. Baek nearly takes Jong-hyeon out with a blade before Dong-ju barrels in for the save. Still, they’re overwhelmed, and Ju-yeong’s crew gets away with the drugs, ripping the tracker off just to rub it in.

After the dust settles, Jae-hong is hospitalized, and the team fears Han-na’s been taken. But plot twist: she’s clinging to the outside of the truck like an action hero. While Dong-ju and Jong-hyeon scramble to find her, Han-na starts dropping clues; shoes, accessories, anything to mark the way. Eventually, the guys spot tire tracks and a glove with a license plate: 4131. They’re back on the trail.

Knowing there might be a mole at the station, Man-sik brings them to Insung Pawnshop instead of HQ. There, with help from Geum-nam, they track down bald eagle-tattooed Gwang-se, who’s been hiding drugs in stuffed animals and pinky-swears to stay alive. He spills about a new deal: Ju-yeong is working with the Japanese Yakuza, and Golden Bunny’s former turf is now Baek’s playground.

Dong-ju and Jong-hyeon confront Golden Bunny, but the guy’s obviously been scared silent. And when he drops metal teeth, his brother Silver Bunny’s, on the table, it’s clear Ju-yeong is tightening his grip.

Meanwhile, Ju-yeong is brokering a deal with a Japanese businessman. To prove he’s not bluffing, he kills the interpreter mid-meeting. Deal sealed with a bullet.

Unbeknownst to them all, Han-na is hiding among the shipment being smuggled onto a Russian ship. She eavesdrops on Leo and Yeon-ha, picking up clues and shockingly realizes Leo is the man who murdered her father. Her quiet infiltration doesn’t last long. Ju-yeong and Baek catch her snooping and knock her out cold. They find nothing on her (thanks to her earlier toss-the-evidence plan) and lock her in a container with two corpses, planning to dump her in the Pacific.

Before that, she gets a chilling moment with Leo, who confirms it, he killed Ji Ho-cheol. Her father.

But Han-na’s not done yet. She swipes a phone from one of Ju-yeong’s thugs and sends out a desperate, patchy emergency call. SCIT picks it up and races to the Geumpo Shipyard. The ship: Victory. Their mission: save Han-na.

The team infiltrates with Gwang-se’s help, using him as bait to sneak aboard. Dong-ju finds Han-na in the container, while Jong-hyeon fends off the goons. But Baek isn’t far behind, he stabs Jong-hyeon in the gut, and time is running out.

Dong-ju charges deeper into the ship to create a diversion while Jong-hyeon tries to get Han-na out. Just as they make progress, Leo arrives and fires. Jong-hyeon takes a bullet in the shoulder—meant for Han-na—and collapses into the water below.

Han-na is frozen. Shocked. Heartbroken.

The team is in pieces. The ship is crawling with enemies. And our heroes are scattered and wounded.

Good Boy just turned the pressure up to eleven, and with only a few episodes left, it’s clear: not everyone’s getting out clean.

Team Scattered, Lines Crossed, and Dong-ju Strikes Back

Episode 10 of Good Boy picks up in the chaos of the shipyard, Jong-hyeon shot, plunging into the water. Dong-ju doesn’t hesitate. He dives in, drags him out, and the two barely escape with sirens closing in and the gangsters scattering.

Jong-hyeon is rushed to the hospital, and we hit the classic waiting room scene; silent, anxious, the team barely holding it together. He makes it through surgery and ends up in intensive care. He’s alive, but it’ll be a long road back.

Meanwhile, Dong-ju’s still hiding the fact that his neurological condition is worsening. He’s having symptoms, but he's saying nothing because of course he’s not.

Ju-yeong, fresh off another crime spree, tries to reach the Mayor of Insung. The Mayor dodges the call. Bad move. Ju-yeong crashes a high-profile dinner, flips the vibe into nightmare mode, stuffs a wad of cash into the Mayor’s mouth, and forces him to mobilize the Customs department for his next move. Ju-yeong isn’t just flexing power, he’s reminding everyone who’s really in charge.

Back at HQ, things fall apart. Man-sik is blaming himself for putting the team together, feeling like he got greedy and dragged everyone down with him. To make it worse, their entire department is officially disbanded.

Cut to three months later: the gang’s not only split, they’re scattered.

Jong-hyeon is finally discharged from the hospital and learns the bad news. Jae-hong’s back with traffic duty. Man-sik’s stuck mediating domestic disputes. Han-na’s buried in a windowless records room. Dong-ju? He’s mopping floors, literally. He’s also crashing at Man-sik’s place, and we get a flashback to why these two are so tightly bound.

Turns out, Man-sik’s been Dong-ju’s unofficial father figure since day one. He saw a troubled, angry kid and steered him into boxing, giving him purpose and discipline. Every time Dong-ju’s hit the bottom, Man-sik’s been the one pulling him back up.

Meanwhile, Han-na visits Jong-hyeon in the hospital. He opens up about his ankle injury and their past, wondering if things would’ve been different if he’d told her sooner. It’s tender, it’s bittersweet, and it’s very clear he’s still not over her.

Elsewhere, Yeon-ha meets with Ju-yeong, but the power dynamic has flipped. Ju-yeong knows about her sister and threatens to reunite them, as soon as the next batch of Candy hits the streets. Cold. Calculated. Cruel.

Then, in the strangest twist, Ju-yeong invites Dong-ju out for a meal. It starts casual. It gets awkward. And it ends with a veiled warning: stop fighting or you’ll stay a punching bag forever. Dong-ju doesn’t say much, but we already know, he’s not quitting.

Back in the records room, Han-na digs into the "Black Cat" lead she overheard from Leo. It takes her to a smuggling case tied to a figure named Oh Dollar, a Russian Far East legend. Listed in the files as “Smuggle Oh Bong-chan,” the man supposedly died 15 years ago from a gunshot wound to the head. Is this really a cold case or a cover-up?

While Han-na investigates from the shadows, Dong-ju goes full vigilante. He starts hunting down Ju-yeong’s foot soldiers by tracking their signature watches. One by one, he dismantles their operations, shutting down every shady business, warehouse, and laundering front tied to Ju-yeong.

News reports start popping up. The team takes notice. They know who’s behind it.

Dong-ju’s back on the warpath.

He may be suspended, isolated, and running on fumes, but the gloves are off. He’s not waiting for permission. He’s not holding back. And the next target? Already in his sights.

DramaZen's Opinion

Episodes 9 and 10 of Good Boy came swinging with heartbreak, tension, and a much-needed revenge arc and I’m thriving on it.

Episode 9 had me holding my breath (literally) as Jong-hyeon took a bullet and tumbled into the water. Dong-ju’s dive to save him was pure drama gold. Han-na clinging to the truck like a stunt double? Incredible. And then the shipyard chaos? I was on the edge of my seat. The cliffhanger hit hard, especially when Jong-hyeon went down again to protect Han-na. My heart.

Then Episode 10 flipped the switch. The team’s disbanded, everyone’s scattered, and Ju-yeong is out here force-feeding the mayor cash. Dong-ju mopping floors while secretly tracking down Ju-yeong’s men? A vibe. And that dinner scene? So tense, I could barely chew my snacks. The moment the news reports started rolling in and everyone realized Dong-ju was back on the hunt? Chills.

This show just keeps leveling up. The stakes are higher, the villains are nastier, and Dong-ju is finally fighting like he has nothing left to lose. Let’s go.
