In the Good Boy Episode 4, the June 8th episode of JTBC’s weekend drama picked up speed with more action and deeper character moments. The focus this time was split between an intense chase and a few emotional flashbacks that gave more context to the characters’ choices. There was also a glass window worth 3.3 million won that didn’t survive the tension.
In this episode, the team kept trying to catch a suspect called Monkey. Yoon Dong-joo (played by Park Bo-gum), Go Man-sik (Heo Sung-tae), Kim Jong-hyun (Lee Sang-yi), Shin Jae-hong (Tae Won-seok), and Ji Han-na (Kim So-hyun) all worked together. But despite their effort, catching Monkey wasn’t easy. Kim Jong-hyun chased him down until the very end but still lost him.
The drama didn’t just focus on action, though. It gave more background on Ji Han-na’s past and what led her to become a police officer. This added depth to her story and helped viewers understand her more clearly.
She finally got access to the investigation records of her late father, Sergeant Ji Ho-chul. She received them from Chief Hwang Kyung-chul (Seo Hyun-chul). The files said her father died from a gunshot to the head. There was also a note about a possible link to the Russian mafia group called “Black Cat.” Ji Han-na broke down while reading them. Her father’s case had been closed years ago as an unsolved case.
As she looked through the records, memories from her childhood came back. One scene showed her eating hamburgers with her father. She had once asked him to show her a gun, since she was a young shooting athlete at the time. But he had refused. He said real guns were for bad people. She smiled and said she would become a police officer too. Her father had simply smiled and agreed. It was a short, warm scene, but it said a lot.
Later in the episode, Ji Han-na connected a watch from her father’s things to an old hit-and-run case. This pushed her to join the violent crimes unit. Her energy and focus added something new to the team dynamic.
Park Bo-gum’s Punch and a Costly Mistake
The tension didn’t stop there. Yoon Dong-joo had a heated moment with Min Ju-young (Oh Jung-se). During their confrontation, he hit a glass window in anger. The window cracked and then shattered completely. Turns out, the repair cost for the glass was 3.3 million won.
The scene turned slightly humorous after the fact. Go Man-sik looked at Dong-joo and asked why he had caused such a mess right after waking up. Dong-joo replied that he didn’t mean to break it; he just touched it. Man-sik then jokingly held up a fly swatter to Dong-joo’s face and said, “Should I touch your face lightly too?”
Shin Jae-hong showed him the repair bill. It wasn’t cheap. Man-sik told Dong-joo to cover the expense himself. Then Kim Jong-hyun looked over the document and said, “It’s double-laminated. Of course it’s expensive.” Dong-joo shot back, “Do you own a glass shop?” Jong-hyun replied, “Yeah, I’m the son of a glasshouse.” It was a quick moment of dry humor between the team members.
A Quiet Confession Catches Viewers Off Guard
The episode also had a soft, more personal scene. Yoon Dong-joo and Kim Jong-hyun were on a stakeout together. While they were waiting in the car, Dong-joo joked about Jong-hyun coming from a rich family. He asked why someone with so much money would become a police officer. Jong-hyun answered plainly: “It’s a hobby.”
When Dong-joo asked again why he joined the special unit, Jong-hyun’s answer surprised him. “Same reason as you,” he said. “I still like Han-na.” It was a small moment, but it made things more interesting. Now there’s more than one layer of tension on the team.
This episode of Good Boy managed to balance action, humor, and emotion well. Each scene felt connected to the bigger picture. Ji Han-na’s personal history is finally taking shape, and the team’s chemistry is becoming clearer. The long chase for Monkey still continues, but the drama made room to explore what really drives its characters.
