Good Boy Episode 6 Recap in 60 Seconds:
- Surprise kiss shocks Dong-ju
- His health gets more mysterious
- Drug case explodes with big names involved
- Emotional twist: Jeong Mi-ja collapses
- Han-na’s mom = unexpected villain?
In Good Boy Episode 6, Yoon Dong-ju wasn’t expecting a kiss. That’s clear. When Ji Han-na leaned in and kissed him without warning, he fainted. Actually passed out. In episode 6 of JTBC’s weekend drama Good Boy, viewers saw a fun but odd reaction from Yoon Dong-ju, played by Park Bo-gum.
Right after the kiss, he collapsed on the ground. The medical team arrived fast and checked him. When they asked if he could see clearly, he said yes, but kept staring only at Han-na. He looked like a confused puppy. Turns out, he had mild heatstroke. That’s what the doctors said. But when his team asked about it, he claimed he felt dizzy all of a sudden. Ji Han-na, played by Kim So-hyun, brushed it off and told everyone he was just talking nonsense from the heat.
Park Bo-gum’s character isn’t just physically collapsing—he’s emotionally unraveling. The heatstroke, the mood swings, the impulsive decisions—they point toward psychological fatigue. It’s subtle, but it’s there. This writing choice brings realism to a genre that often glamorizes toughness. Viewers may laugh when he fainted post-kiss, but it’s actually a brilliant metaphor for how emotionally unprepared he is for affection.
Still, that moment changed something. The mood between Dong-ju, Han-na, and Kim Jong-hyun (played by Lee Sang-yi) got more intense. It’s clear there’s something going on between the three of them. There’s tension, small glances, and now a surprise kiss. That love triangle is heating up. But this episode wasn’t just about romance. Far from it.
Things Heat Up Around the Drug Case and Yoon Dong-ju’s Health
The rest of the story picked up speed. The team continued digging into the drug case. They focused more on Min Joo-young, a civil servant with way too many secrets. Dong-ju thought Min was using a second phone to hide information. He believed the fake phone was in the parking tower, so he went looking for it.
In a scene that felt too real, he searched through a smelly sewer alley. He thought the other half of a broken phone was in there. Ji Han-na found him collapsed again—this time in a corner. She panicked, but he woke up and acted like nothing had happened. He even joked. But deep down, something wasn’t right. His symptoms were strange. He just didn’t tell anyone.
Later, Dong-ju brushed off questions from Go Man-sik (played by Heo Sung-tae) about his hospital results. He just said it was nothing. But the hospital sent a message later—he actually needs more tests. They said he should get counseling. Clearly, something is going on with his health that he’s hiding from others.
Corruption Unveiled and Dong-ju’s Emotional Breaking Point
Meanwhile, the drug team made progress. They found out that TAE Corporation had bought Cheongil Shipping super cheap. Then, they used it to smuggle drugs into the country, hidden as fish. J9 Security Service, run by Oh Jong-goo (played by Jung Man-sik), handled transport. Min Joo-young, who works in customs, was helping them.
Even worse, TAE Corporation’s owner had ties with Noh Deok-gyu, the mayor of Inseong. That mayor was also being protected by Jo Pan-yeol, the city’s police chief. But at the top of this corrupt chain was Min Joo-young.
There was another twist. Ji Han-na found out that the woman who saw the drug lord called “Devil” was actually the Devil herself. Her name is Kim Yeon-ha (played by Lee Ho-jung). That changed everything. It’s not who they thought.
On the other side, Min Joo-young turned violent. Angry about the investigation, he attacked the mayor. He screamed at him, yanked his tie, threw him down, and even grabbed his mouth in a disturbing way. It showed how dangerous and unstable he is. Then, he said he’d go after Dong-ju next.
As expected, Dong-ju was already suspicious. He got a call from Jeong Mi-ja, but couldn’t reach her. Dong-Ju felt something was off. He rushed to her restaurant. Sadly, she had already collapsed. Paramedics were there, taking her away. On the table, Dong-ju saw something small—a kimbap without cucumbers. That’s how he knew Min Joo-young had been there. Min is known for being a picky eater.
Key Players in the Drug Ring:
-
Min Joo-young (customs officer)
-
TAE Corp (front for smuggling)
-
Noh Deok-gyu (mayor)
-
Jo Pan-yeol (police chief)

The Weight of the Past and a Glimmer of Hope
Dong-ju’s anger reached its peak. Thinking of his past, his mom’s pain, and how Jeong Mi-ja cared for him like family, he snapped. He went to Min Joo-young and punched him. All of these points point to one thing. Dong-ju is not okay. Physically and emotionally, he’s running on fumes. But here’s something light. No matter how many bad guys Dong-ju catches, winning over Han-na’s mom might be harder. That lady is tough. And she wants a rich son-in-law. Dong-ju? He’s broke. He’s got a long way to go.
This episode had a lot going on—romance, danger, secret phones, and a drug cartel. But it also showed a softer, human side. Dong-ju isn’t just a smart investigator. He’s also a guy trying to make sense of his feelings. And maybe, just maybe, dealing with more than he can handle.
Could Dong-ju be suffering from PTSD? Is Han-na hiding something about his health? Is the “Devil” really Kim Yeon-ha—or is that a misdirect? Drop your theories below! Let’s see what happens next. See you in episode 7’s recap.
